# Stop Loss using Conditional Algo Orders with Binance USD-M APIs & WebSockets

Binance USD-M Algo conditionals are one way to implement stop losses, trailing stops, and explicit conditional take-profit. This guide walks through request shapes, [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) context lookup, and private stream reconciliation. Ordinary fixed TP should use regular LIMIT orders instead.

Before building Binance request objects, verify the current SDK method names, request types, required fields, and Binance USD-M Algo rules from the installed package and docs.

## Default Scope

- Runtime: Node.js LTS
- Recommended language: TypeScript
- Package: [binance](https://siebly.io/sdk/binance/javascript/tutorial)
- Product: Binance USD-M Futures
- Implement execution for when [EXECUTION_MODE](https://siebly.io/reference/glossary#execution-mode)=DEMO, TESTNET, or LIVE is enabled and all gates pass, but keep that path disabled by default.
- [EXECUTION_MODE](https://siebly.io/reference/glossary#execution-mode)=DRY_RUN_PRIVATE is the default local mode for bounded USD-M conditional algo order request candidates.
- Credentials: scoped API keys from environment variables only

## Implementation Phases

### 1. Verify the current Algo surface

Before coding, inspect the installed package declarations and source for the USD-M client, Algo methods, request types, response types, user-data update types, and order ID utilities.

- Expected methods include submitNewAlgoOrder(...), getOpenAlgoOrders(...), and cancelAlgoOrder(...).
- Expected types include FuturesNewAlgoOrderParams, FuturesAlgoConditionalOrderTypes, FuturesAlgoOrderResponse, and formatted futures Algo user-data update payloads.
- Record the latest installed package version as metadata plus the exact types checked in the project README.

### 2. Pick the right order path

For USD-M exits, do not assume every TP/SL belongs on the Algo Service. Check whether the current task belongs on regular order methods or the futures Algo path.

- Use [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) for USD-M Algo conditionals.
- Treat [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) as a Binance custom order ID. Generate it with the same SDK order ID utilities as newClientOrderId, preferably generateNewOrderId(...) or client.generateNewOrderId(), and satisfy the same prefix, length, and character checks.
- Keep regular order newClientOrderId handling separate from Algo clientAlgoId handling.
- Fixed TP and DCA use regular LIMIT orders. A DCA LIMIT may fill immediately at limit-or-better or rest at the submitted limit price; both are normal LIMIT behavior. Do not add maker-only, post-only, mark-price, quote-freshness, marketability, or forced-maker gates unless explicitly configured.
- Track active Algo exits separately from regular open orders before deciding whether an exit already exists.

### 3. Build valid conditional requests

[EXECUTION_MODE](https://siebly.io/reference/glossary#execution-mode)=DRY_RUN_PRIVATE is the default local mode for sanitized USD-M conditional algo order request objects. Validate the quantized price, quantity, notional, positionSide, and field combinations before any [EXECUTION_MODE](https://siebly.io/reference/glossary#execution-mode)=DEMO, TESTNET, or LIVE submission path can call Binance.

- For an explicit conditional take-profit, verify and use the current valid Algo type such as TAKE_PROFIT.
- Do not use Algo TAKE_PROFIT for the default fixed TP slot in the position manager.
- For a close-position stop-market, use STOP_MARKET with closePosition=true and omit quantity and reduceOnly.
- Do not use strategy-language values such as TAKE_PROFIT_LIMIT unless current Binance docs and package types explicitly support them.

### 4. Validate mutually exclusive fields

The costliest mistakes here are field mixes that compile but Binance rejects. Add local validation before building the final request.

- Reject closePosition=true with quantity.
- Reject closePosition=true with reduceOnly unless current docs say the combination is valid.
- Omit undefined optional fields under strict TypeScript settings.
- Keep workingType and priceProtect explicit when the strategy depends on trigger semantics.

### 5. Use trusted state before replacing exits

Private user-data events are the normal way to keep local [account state](https://siebly.io/reference/glossary#accountstate) current. Use REST hydration only for startup, reconnect, scoped recovery, missing prerequisites, unknown outcomes, or conflicting evidence before creating, replacing, or cleaning up exits.

- Use getOpenAlgoOrders(...) during startup, reconnect, and scoped recovery reconciliation; do not call it just because a healthy private user-data event arrived.
- When private ALGO_UPDATE and matching position or account-state evidence have been ingested, plan from the private-stream account state without REST hydration.
- Classify app-owned Algo orders from [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) context lookup plus persisted metadata.
- Only open app-owned orders and pending confirmations should block new submissions for a logical slot. Historical cancelled, expired, rejected, and filled orders are metadata.
- For the default manager, [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) follows the [custom order ID](https://siebly.io/reference/glossary#custom-order-id) rule: keep product, symbol, role, side, step, order kind, lifecycle, generation, recovery state, and other strategy state out of the ID text.
- If scoped open Algo hydration reports an active order while recent history has an older terminal row for the same clientAlgoId, keep the active state and avoid replacement.

### 6. Process private updates once

Formatted user-data events should update local state from typed fields, not from whole-object JSON serialization.

- Prefer formattedUserDataMessage for private state processing.
- For formatted ALGO_UPDATE, read clientAlgoId, symbol, positionSide, orderType, and status from algoOrder.*, not from root fields.
- If formattedMessage is also inspected, derive and test a stable dedupe key before mutating order state.
- If an Algo update arrives while reconciliation, buffered replay, planning, or submission is active, defer it to the active workflow instead of starting a competing planner.
- A user-data-triggered Algo replan should update from trusted private user-data state before planning. Use REST reconciliation only when startup, reconnect, sync-required, exception, rejection, unknown-state, or conflicting-state evidence makes local state untrusted. If a deferred work item contains only already-applied user-data events and no buffered events remain, skip the duplicate replan.
- Redact user-data [wsKey values](https://siebly.io/reference/glossary#ws-key) because they may contain listen-key-like material.

## Dry-run request path

Module names can vary; keep this verified request-object flow intact.

- Load symbol, side, positionSide, quantity, trigger, price, and risk settings from config.
- Create USDMClient with strict optional-field and logging options verified from the installed package.
- During startup, reconnect, or scoped recovery, hydrate exchange filters and open Algo orders before first planning from untrusted local state.
- Build request objects in dry-run and validate field combinations locally.
- Log sanitized request summaries with clientAlgoId, role, symbol, side, and reason.
- Enable DEMO, TESTNET, or LIVE submission only after explicit configuration, scoped credentials, and reviewed code.
- After an accepted DEMO, TESTNET, or LIVE request, record pending confirmation state before waiting for private stream confirmation.

## Request validation

The guide gives the shape to verify. The installed package types and Binance docs remain the authority for exact literals and field rules.

- Validate tick size, step size, quantity, and notional from hydrated USD-M filters.
- Reject strategy-language order types that are not present in the current Algo type union.
- Reject closePosition=true with quantity or reduceOnly unless current docs say otherwise.
- Use [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) for Algo conditionals and apply the same SDK generation, prefix, length, and character checks used for newClientOrderId.

## User-data handling

Algo updates should reconcile existing state, not start a second overlapping planning pass.

- Classify formatted ALGO_UPDATE from eventType plus algoOrder.clientAlgoId, algoOrder.symbol, algoOrder.positionSide, algoOrder.orderType, and algoOrder.algoStatus.
- Choose formattedUserDataMessage or formattedMessage for private state processing; do not process both.
- After reconnect, enter recoveryRequired for the affected product, hydrate open Algo orders again, replay buffered events, then resume order mutations only when state is coherent.

## Request examples

These examples intentionally use variables rather than a hardcoded symbol. Verify the current package types before copying them into EXECUTION_MODE=DRY_RUN_PRIVATE, DEMO, TESTNET, or LIVE code.

### Explicit conditional take-profit

Use this only when conditional TP behavior is required. Ordinary fixed TP belongs on regular LIMIT orders. Set useReduceOnly only after the current docs and package types validate reduceOnly for the account mode; otherwise omit it.

```ts
await usdm.submitNewAlgoOrder({
  algoType: 'CONDITIONAL',
  symbol,
  side: exitSide,
  positionSide,
  type: 'TAKE_PROFIT',
  timeInForce: 'GTC',
  quantity,
  price: takeProfitPrice,
  triggerPrice: takeProfitTriggerPrice,
  workingType: 'MARK_PRICE',
  priceProtect: 'true',
  ...(useReduceOnly ? { reduceOnly: 'true' } : {}),
  clientAlgoId,
});
```

### Close-position stop-market

For close-position stops, omit quantity and reduceOnly.

```ts
await usdm.submitNewAlgoOrder({
  algoType: 'CONDITIONAL',
  symbol,
  side: exitSide,
  positionSide,
  type: 'STOP_MARKET',
  triggerPrice: stopTriggerPrice,
  workingType: 'MARK_PRICE',
  priceProtect: 'true',
  closePosition: 'true',
  clientAlgoId,
});
```

### Reject these locally

These are examples of request shapes that should be blocked before a DEMO, TESTNET, or LIVE submission.

```ts
// Invalid for the current USD-M Algo Service:
type: 'TAKE_PROFIT_LIMIT'

// Invalid close-position combination:
{
  closePosition: 'true',
  quantity,
  reduceOnly: 'true',
}
```

## Private user-data lifecycle

Use private stream events for account state, not for readiness shortcuts. A transport event can tell you the socket changed; it cannot prove local order state is safe to act on.

Choose one user-data processing path. If you handle formattedUserDataMessage, do not also process the same user-data payload from formattedMessage unless you add an explicit dedupe key. Do not infer stream failure from quiet private account-event traffic while the SDK transport is healthy; use SDK reconnecting, reconnected, and exception events for stream-health decisions.

| Event | Meaning | Readiness | State use |
| --- | --- | --- | --- |
| open | The WebSocket transport opened. | Useful for transport health only. | Do not update account or order state from this event. |
| response | A command or subscription response was received. | Use for public subscription acknowledgements when applicable. | Rarely enough for listen-key stream state by itself. |
| formattedUserDataMessage | A formatted private account, order, fill, balance, position, or Algo event. | Not a readiness gate. | Preferred dedicated path for private state updates. |
| formattedMessage | A formatted message across public and private streams. | Useful for public streams and broad logging. | Use this or formattedUserDataMessage for private events, not both. |
| reconnecting | The SDK is reconnecting the socket. | Pause downstream live actions and keep buffering where possible. | Mark affected state not ready; do not plan from it until reconnect recovery finishes. |
| reconnected | The socket transport reconnected. | Require scoped resync before management resumes. | Mark local state stale until reconciliation finishes. |
| exception | The socket or listener reported an error. | Enter recoveryRequired for the affected product scope. | Log a sanitized summary and reconcile before acting. |

## Fixture Cases

| Name | Purpose | Expected result |
| --- | --- | --- |
| Valid explicit conditional take-profit | Proves the project builds the current take-profit Algo request shape. | The request uses TAKE_PROFIT, quantity, price, triggerPrice, clientAlgoId, and only account-mode-valid optional reduceOnly fields. |
| Valid close-position stop-market | Proves close-position stops avoid invalid field mixes. | The request uses STOP_MARKET, triggerPrice, closePosition=true, and omits quantity and reduceOnly. |
| Invalid strategy-language take-profit type | Proves stale order type names are caught locally. | TAKE_PROFIT_LIMIT is rejected before Binance can return an invalid order type error. |
| Invalid close-position field mix | Proves mutually exclusive fields are validated before submission. | closePosition=true with quantity or reduceOnly is rejected locally. |
| Scoped open Algo hydration | Proves startup, reconnect, or scoped recovery reconciliation sees existing app-owned exits. | Existing app-owned TP/SL Algo orders prevent duplicates unless replacement is explicitly required. |
| Scoped open Algo hydration with stale terminal history | Proves older terminal Algo history does not hide a currently open app-owned exit. | Current open Algo state wins, and the planner emits no duplicate replacement for that clientAlgoId. |
| Algo update during active workflow | Proves Algo confirmations do not start a competing planner during reconciliation, replay, planning, or submission. | The update is deferred until the active workflow can replay trusted private state, or run scoped recovery if trust is unresolved, then planning sees current open Algo state. |
| Algo user-data update | Proves private Algo updates reconcile app-owned state once. | The update is classified from typed fields and does not double-apply through two event handlers. |

## Invariants

- [EXECUTION_MODE](https://siebly.io/reference/glossary#execution-mode)=DRY_RUN_PRIVATE is the default local mode for sanitized USD-M conditional algo order request objects.
- USD-M Algo conditionals use clientAlgoId, not newClientOrderId.
- Simple-manager [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) values follow the [custom order ID](https://siebly.io/reference/glossary#custom-order-id) rule; lifecycle/generation IDs are not the default.
- Limit take-profit and close-position stop-market requests must use the current package types and Binance field rules.
- closePosition=true must not be mixed with quantity or reduceOnly unless current docs explicitly allow it.
- At startup, reconnect, or scoped recovery, Algo open orders are hydrated separately from regular open orders on Binance.
- Private user-data events are processed once and redacted before logging.

Requirements:
- If the Node.js project uses environment variables or creates .env.example, make .env loading automatic for every normal local entrypoint before config parsing. Prefer Node.js built-in --env-file/--env-file-if-exists in package scripts when supported by the project runtime; otherwise use process.loadEnvFile, dotenv/config, or the repo-local env loader. Document that real process environment variables override .env. Ensure all variables in the .env.example are commented clearly with their purpose and accepted values, and that the README references the .env.example and documents .env loading and precedence.
- Order-capable execution mode contract: implement one environment variable, EXECUTION_MODE, with exactly these values: PUBLIC, READ_ONLY_PRIVATE, DRY_RUN_PRIVATE, DEMO, TESTNET, LIVE. Set the default for order-capable local runs and .env.example to EXECUTION_MODE=DRY_RUN_PRIVATE. PUBLIC uses no API keys and cannot create private clients, account readers, [order intents](https://siebly.io/reference/glossary#order-intent), or exchange write requests. READ_ONLY_PRIVATE may use read-only credentials for balances, orders, fills, native positions, or local position-derivation inputs, but cannot place, amend, cancel, borrow, transfer, lever, or otherwise mutate exchange state. DRY_RUN_PRIVATE may use private state and must build the exact place/amend/cancel request objects that DEMO, TESTNET, or LIVE would send, but the submitter records them without calling exchange mutation endpoints. DEMO and TESTNET are write-capable only when the selected exchange supports those non-production venues; if unsupported, they must fail closed with a clear configuration error and must never silently route to production. DEMO may call place/amend/cancel endpoints only against the selected exchange's demo or sandbox environment, and TESTNET may call them only against the selected exchange's testnet environment. LIVE is the only mode that may call production exchange place/amend/cancel endpoints. The finished order-capable project must include the LIVE execution path for the selected exchange and supported DEMO/TESTNET paths where those venues exist; do not leave LIVE submission as a TODO.
- Verify USDMClient, submitNewAlgoOrder(...), getOpenAlgoOrders(...), cancelAlgoOrder(...), FuturesNewAlgoOrderParams, FuturesAlgoConditionalOrderTypes, FuturesAlgoOrderResponse, formatted futures Algo user-data update types, clientAlgoId, getOrderIdPrefix(...), generateNewOrderId(...), and closeAll(...) from the installed package before coding.
- Use variables for symbol, side, positionSide, quantity, prices, triggers, and clientAlgoId. Do not hardcode a trading symbol.
- Treat [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) as a Binance custom order ID. Generate it with the same SDK order ID utilities as newClientOrderId, preferably generateNewOrderId(...) or client.generateNewOrderId(), and satisfy the same prefix, length, and character checks.
- For the simple position manager, [clientAlgoId](https://siebly.io/reference/glossary#custom-order-id) follows the [custom order ID](https://siebly.io/reference/glossary#custom-order-id) rule: keep product, symbol, role, side, step, order kind, lifecycle, generation, recovery state, and other strategy state out of the ID text.
- For ordinary fixed take-profit, use regular submitNewOrder LIMIT with newClientOrderId. For explicit conditional take-profit, verify and use the current valid Algo type such as TAKE_PROFIT. Do not invent TAKE_PROFIT_LIMIT unless current package types and Binance docs support it.
- For close-position stop-market, use STOP_MARKET with closePosition=true and omit quantity and reduceOnly unless current docs say otherwise.
- Hydrate open Algo orders during startup, reconnect, or scoped recovery before planning replacement exits from an untrusted local state. During healthy private-stream operation, update local account state from user-data events and continue without REST hydration. Only open app-owned Algo orders and pending confirmations should block custom clientAlgoId reuse.
- Do not let older terminal Algo history overwrite current open app-owned Algo state or pending confirmation state for the same clientAlgoId.
- If an Algo user-data update arrives while reconciliation, buffered replay, planning, or submission is active, defer it to the active workflow. Idle user-data replans should update from trusted private user-data state before planning. Use REST reconciliation only when startup, reconnect, sync-required, exception, rejection, unknown-state, or conflicting-state evidence makes local state untrusted. If a deferred work item contains only already-applied user-data events and no buffered events remain, skip the duplicate replan.
- Process private user-data updates once. Prefer formattedUserDataMessage, or dedupe explicitly if formattedMessage also sees private events. For formatted ALGO_UPDATE, verify and read algoOrder.clientAlgoId, algoOrder.symbol, algoOrder.positionSide, algoOrder.orderType, and algoOrder.algoStatus; do not read root clientAlgoId.
- Redact user-data [wsKey values](https://siebly.io/reference/glossary#ws-key), listen keys, signatures, API keys, signed URLs, request bodies, and order-intent context before logging.
- Add fixtures for valid explicit conditional take-profit, valid close-position stop-market, default fixed TP rejected from the Algo path, invalid conditional take-profit type, invalid closePosition field mix, scoped open Algo hydration, duplicate clientAlgoId, precision/filter failures, and formatted ALGO_UPDATE field paths.
- Add a fixture where scoped open Algo hydration reports an active app-owned exit but recent history has an older terminal row for the same clientAlgoId.
- Add a fixture where an Algo update arrives during active reconciliation and is deferred before planning.

Acceptance criteria:
- [EXECUTION_MODE](https://siebly.io/reference/glossary#execution-mode)=DRY_RUN_PRIVATE is the default execution mode, where the implementation builds and logs sanitized request objects equivalent to the DEMO, TESTNET, or LIVE submission payloads without submitting to the exchange.
- EXECUTION_MODE is documented as the only execution-mode switch, with allowed values PUBLIC, READ_ONLY_PRIVATE, DRY_RUN_PRIVATE, DEMO, TESTNET, LIVE. Tests or fixtures prove PUBLIC and READ_ONLY_PRIVATE cannot build or submit exchange writes, DRY_RUN_PRIVATE builds the final request objects without calling exchange mutation endpoints, DEMO and TESTNET refuse unsupported exchange venues and can write only to the selected non-production venue, and LIVE is the only mode that can call production exchange mutation endpoints.
- Invalid field combinations are rejected locally before Binance can reject them.
- Startup/reconnect/scoped recovery hydration reconciles open Algo orders before replacement planning from untrusted local state, and healthy user-data updates can update trusted state without REST.
- Current open Algo state wins over older terminal history for the same app-owned clientAlgoId.
- Algo user-data-triggered planning never forces REST reconciliation while private state remains trusted; it uses scoped REST only when trust is unresolved.
- Formatted ALGO_UPDATE confirms app-owned Algo state through algoOrder.clientAlgoId and enters scoped recovery if that required path is missing.
- Private user-data events do not double-apply through both formattedUserDataMessage and formattedMessage.

Recursive completion workflow:
1. Before implementation, save this exact prompt in docs/AI_PROMPT.md (or docs/SPEC.md when that is the project standard) and write docs/PLAN.md with phases, invariants, tests or fixtures, docs to update, and acceptance gates.
2. Review docs/PLAN.md for missing workflows, unsafe assumptions, product/exchange-specific leakage, unclear state ownership, confirmation or recovery gaps, missing tests, and incomplete docs. Update docs/PLAN.md and repeat until one full review pass finds no actionable changes.
3. Implement one plan phase at a time. After each phase, review changed code, tests, fixtures, docs, generated artifacts, and runtime workflows against docs/PLAN.md and this prompt. Fix gaps and repeat until that phase has no actionable changes before starting the next phase.
4. After all phases, run a full-depth project review across every workflow, lifecycle, state transition, error path, and artifact. This is not a shallow summary pass. Fix every actionable gap and repeat until a full pass finds no further changes, then record the final review outcome in docs/PLAN.md.
