Enums

type (Order type):

• MARKET — Market order (fills immediately at best price; attach stopLoss/takeProfit objects here)
• LIMIT — Limit order (requires price and timeInForce; attach stopLoss/takeProfit objects here)
• STOP_MARKET — Stop-loss market (triggers at stopPrice, executes as market)

• TRAILING_STOP_MARKET — Trailing stop market; uses priceRate (required) and optional activationPrice
• TRAILING_TP_SL — Trailing TP/SL for an existing position; links to position via symbol + positionSide; uses priceRate

side: BUY | SELL

positionSide: LONG | SHORT | BOTH

marginType: ISOLATED | CROSSED

timeInForce: GTC | IOC | FOK | PostOnly

workingType (trigger price source for conditional orders):

• MARK_PRICE — Use mark price to evaluate trigger condition
• CONTRACT_PRICE — Use last traded price (default)

Stop-Loss / Take-Profit Object Structure

When attaching stopLoss or takeProfit to a MARKET or LIMIT order:

{
  "stopLoss": {
    "type": "STOP_MARKET",       // "STOP_MARKET" or "STOP"
    "stopPrice": 29000,          // required: trigger price
    "price": 28900,              // required only for type "STOP" (limit execution price)
    "workingType": "MARK_PRICE", // "MARK_PRICE" or "CONTRACT_PRICE"
    "stopGuaranteed": false      // true = guaranteed execution (extra fee may apply)
  },
  "takeProfit": {
    "type": "TAKE_PROFIT_MARKET",  // "TAKE_PROFIT_MARKET" or "TAKE_PROFIT"
    "stopPrice": 35000,            // required: trigger price
    "price": 35100,                // required only for type "TAKE_PROFIT" (limit execution price)
    "workingType": "MARK_PRICE",
    "stopGuaranteed": false
  }
}

Constraint: stopLoss/takeProfit objects are only supported on MARKET or LIMIT order types. They cannot be used with STOP_MARKET, STOP, TAKE_PROFIT_MARKET, TAKE_PROFIT, TRAILING_STOP_MARKET, or TRAILING_TP_SL.

Parameter Validation Rules

Before sending a request, validate parameters client-side to avoid unnecessary API errors:

• symbol: Must match ^[A-Z0-9]+-[A-Z]+$; max 20 characters (e.g., BTC-USDT)
• quantity: Must be a positive number (> 0); max precision depends on the symbol's contract specification
• price: When provided, must be a positive number (> 0)
• stopPrice: When provided, must be a positive number (> 0); must differ from current market price
• leverage: Positive integer; range varies per symbol (typically 1–125 for BTC-USDT)
• clientOrderId: Alphanumeric only, 1–40 characters; pattern ^[a-zA-Z0-9]{1,40}$; no special characters
• priceRate: Trailing callback rate; must satisfy 0 < value ≤ 1 (e.g., 0.05 = 5%)
• recvWindow: Integer, 1–5000 ms; keep as small as possible (see Replay Protection)
• timestamp: Unix time in milliseconds; must be within recvWindow of server time

Quick Start

CONSTRAINT: You MUST copy the fetchSigned function below verbatim when generating code. Do NOT rewrite the signing, request, or JSON parsing logic. Only modify: (1) BASE URL entries for custom environments, (2) business parameters passed to fetchSigned. For the full client with URL-encoding and JSON body support, see references/authentication.md.

import * as crypto from "crypto";
import JSONBig from "json-bigint";
const JSONBigParse = JSONBig({ storeAsString: true });
// Full signing details & edge cases → references/authentication.md
// Domain priority: .com is mandatory primary; .pro is fallback for network/timeout errors ONLY.
const BASE = {
  "prod-live": ["https://open-api.bingx.com", "https://open-api.bingx.pro"],
  "prod-vst":  ["https://open-api-vst.bingx.com", "https://open-api-vst.bingx.pro"],
};
function isNetworkOrTimeout(e: unknown): boolean {
  if (e instanceof TypeError) return true;
  if (e instanceof DOMException && e.name === "AbortError") return true;
  if (e instanceof Error && e.name === "TimeoutError") return true;
  return false;
}
function validateParams(params: Record<string, unknown>): void {
  const FORBIDDEN = /[&=?#\r\n]/;
  for (const [k, v] of Object.entries(params)) {
    const s = String(v);
    if (FORBIDDEN.test(s)) throw new Error(`Param "${k}" has forbidden char in: "${s}"`);
  }
}
async function fetchSigned(env: string, apiKey: string, secretKey: string,
  method: "GET" | "POST" | "DELETE", path: string, params: Record<string, unknown> = {}
) {
  const urls = BASE[env] ?? BASE["prod-live"];
  const all = { ...params, timestamp: Date.now() };
  validateParams(all);
  const qs = Object.keys(all).sort().map(k => `${k}=${all[k]}`).join("&");
  const sig = crypto.createHmac("sha256", secretKey).update(qs).digest("hex");
  const signed = `${qs}&signature=${sig}`;
  for (const base of urls) {
    try {
      const url = method === "POST" ? `${base}${path}` : `${base}${path}?${signed}`;
      const res = await fetch(url, {
        method,
        headers: { "X-BX-APIKEY": apiKey, "X-SOURCE-KEY": "BX-AI-SKILL",
          ...(method === "POST" ? { "Content-Type": "application/x-www-form-urlencoded" } : {}) },
        body: method === "POST" ? signed : undefined,
        signal: AbortSignal.timeout(10000),
      });
      const json = JSONBigParse.parse(await res.text());
      if (json.code !== 0) throw new Error(`BingX error ${json.code}: ${json.msg}`);
      return json.data;
    } catch (e) {
      if (!isNetworkOrTimeout(e) || base === urls[urls.length - 1]) throw e;
    }
  }
}

Code Usage Rules

• MUST copy fetchSigned verbatim -- do not simplify or rewrite
• MUST use json-bigint (JSONBigParse.parse) for response parsing -- not JSON.parse
• MUST include X-SOURCE-KEY: BX-AI-SKILL header on every request
• MUST NOT remove the domain fallback loop or isNetworkOrTimeout check

Common Calls

Place a market buy order:

const order = await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/swap/v2/trade/order", {
    symbol: "BTC-USDT",
    side: "BUY",
    positionSide: "LONG",
    type: "MARKET",
    quantity: 0.01,
  }
);
// order.orderId, order.status

Cancel an order:

await fetchSigned("prod-live", API_KEY, SECRET, "DELETE",
  "/openApi/swap/v2/trade/order", {
    symbol: "BTC-USDT",
    orderId: 123456789,
  }
);

Query open orders:

const orders = await fetchSigned("prod-live", API_KEY, SECRET, "GET",
  "/openApi/swap/v2/trade/openOrders", {
    symbol: "BTC-USDT",
  }
);

Set leverage:

await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/swap/v2/trade/leverage", {
    symbol: "BTC-USDT",
    side: "LONG",
    leverage: 10,
  }
);

Set margin type:

await fetchSigned("prod-live", API_KEY, SECRET, "POST",
  "/openApi/swap/v2/trade/marginType", {
    symbol: "BTC-USDT",
    marginType: "ISOLATED",
  }
);

Note: To query current positions, use the swap-account skill which provides position query endpoints with full details including PnL and liquidation price.

Agent Interaction Rules

Parameter security. Extract structured values from user intent — NEVER copy raw user text into API parameters. Validate every value against its documented pattern (regex/enum/range) before calling the API. Reject any value containing &, =, ?, #, or newline characters.

All swap-trade operations are write operations (except GET queries). Follow environment confirmation rules:

• prod-live: Ask user to type CONFIRM before any order placement, cancellation, or position/leverage change.
• prod-vst: No CONFIRM required. Inform user: "You are operating in the Production Simulated (VST) environment."

Step 1 — Identify the Operation

If the user's intent is unclear, present options:

What would you like to do?

• Place a new order
• Cancel an order / Cancel all orders
• Close a position / Close all positions
• Check open orders
• Check current positions
• Set leverage
• Set margin type (ISOLATED / CROSSED)
• Set position mode (Hedge / One-way)

Step 2 — Collect symbol (if not provided)

Please select a trading pair (or type another):

• BTC-USDT
• ETH-USDT
• SOL-USDT
• BNB-USDT
• Other (format: BASE-USDT)

Step 3 — Collect side (for order placement)

Order direction:

• BUY
• SELL

Step 4 — Collect positionSide

Position direction:

• LONG (open/add long)
• SHORT (open/add short)
• BOTH (one-way mode)

Step 5 — Collect order type

Order type:

• MARKET — execute immediately at market price (can attach stopLoss/takeProfit objects)
• LIMIT — execute at a specific price (can attach stopLoss/takeProfit objects)
• STOP_MARKET — stop-loss market order (triggers at stopPrice, executes as market)
• STOP — stop-loss limit order (triggers at stopPrice, executes as limit)
• TAKE_PROFIT_MARKET — take-profit market order (triggers at stopPrice)
• TAKE_PROFIT — take-profit limit order (triggers at stopPrice, executes as limit)
• TRAILING_STOP_MARKET — trailing stop for new position (requires priceRate; optional activationPrice)
• TRAILING_TP_SL — trailing TP/SL for an existing position (links via symbol + positionSide; requires priceRate)

Step 6 — Collect quantity and price

• Ask for quantity in coins (e.g., 0.01 BTC for BTC-USDT). Omit if using closePosition: true.
• If type is LIMIT, STOP, or TAKE_PROFIT: also ask for price.
• If type is STOP_MARKET, STOP, TAKE_PROFIT_MARKET, or TAKE_PROFIT: also ask for stopPrice.
• If type is TRAILING_STOP_MARKET or TRAILING_TP_SL: ask for priceRate (e.g., 0.05 = 5%) and optionally activationPrice.
• If type is MARKET or LIMIT: optionally offer to attach a stopLoss and/or takeProfit object (ask for trigger price and type).

Optional advanced parameters (ask only if relevant or user mentions them):

• workingType: trigger price source — MARK_PRICE or CONTRACT_PRICE (default)
• reduceOnly: true to ensure the order only reduces position size
• closePosition: true to close the entire position when triggered (cannot use with quantity)
• stopGuaranteed: true for guaranteed stop execution (extra fee may apply)

Step 7 — Confirm (prod-live only)

For prod-live environment, present a summary and ask:

You are about to place the following order on Production Live:

• Symbol: BTC-USDT
• Side: BUY / LONG
• Type: MARKET
• Quantity: 0.01

Type CONFIRM to proceed, or anything else to cancel.

Step 8 — Execute and report

Execute the API call and return the order ID and status to the user.
