Choose "Trade" permissions only (never enable "Withdraw"). Write down the API Key, Secret Key, and Passphrase. Pro tip: Use a dedicated IP whitelist to block unauthorized access. This alone prevents 70% of account takeovers. **āš ļø Risk Alert:** Never share your Secret Key in plain text. A single screenshot can cost your entire portfolio. Always encrypt it in a password manager. - **Step 2: šŸ”„ Master the REST Endpoint for Futures** The correct endpoint is `https://www.okx.com/api/v5/trade/order`. Don't use deprecated V4 endpointsā€”they lack margin modes and position management. Always set the header `Content-Type: application/json`. **āš ļø Risk Alert:** Wrong endpoint = 404 errors or wrong instrument IDs. Always test with a tiny amount first. I've seen traders lose $500 in fees debugging broken endpoints. - **Step 3: šŸ”„ Set the Instrument ID (InstId) Correctly** For BTC-USDT futures, use `"instId":"BTC-USDT-SWAP"`. A common mistake? Using "BTC-USDT" (spot) or "BTC-USD-SWAP" (inverse). Cross-check with the `/api/v5/public/instruments?instType=SWAP` endpoint. **āš ļø Risk Alert:** Wrong instId places orders on the wrong market or fails entirely. Always validate the list to avoid zero-liquidity instruments. - **Step 4: šŸ”„ Configure Margin Mode and Leverage** Always set `"tdMode":"cross"` (cross-margin) or `"isolated"` (isolated). For leverage, call `/api/v5/account/set-leverage` separately. Default leverage is 1x; leaving it empty leads to unexpected liquidations. **Risk Alert:** If you donā€™t set leverage, OKX uses account-level defaults which may be 20x. That 5x trade just became a death spiral. - **Step 5: šŸ”„ Order Type: Market vs. Limit vs. Post-Only** For starters, use `"ordType":"market"` for speed, or `"limit"` with a price. Pro tip: Add `"px":"0"` for market orders to avoid price slippage. Post-only orders (`"ordType":"post_only"`) save fees but require specific price ranges. **Risk Alert:** Market orders during low liquidity can cause 5% slippage. Always check the order book depth via API before executing. - **Step 6: šŸ”„ Size and Time-in-Force** Set `"sz":"0.01"` (for BTC) or appropriate contract size. Use `"tgtCcy":"base_ccy"` for size in coin terms. Time-in-force: `"tdMode":"cash"` for immediate-or-cancel, `"gtc"` for good-till-cancel. **Risk Alert:** Wrong size units can open a 100x position when you meant 1x. Always use limit orders for size control. - **Step 7: šŸ”„ Sign Your Order Request** Generate a timestamp, signature (`HMAC-SHA256` with your Secret Key), and passphrase. The format is: `timestamp + su + method + requestPath + body`. Use ISO 8601 timestamps like `2026-05-15T12:00:00.000Z`. Test with the `/api/v5/trade/order-algo` endpoint first for dry runs. **Risk Alert:** Timestamp skew >30 seconds leads to signature errors. Sync your system clock with NTP servers before every session. - **Step 8: šŸ”„ Deploy and Monitor with Safety Limits** Use the API response's `"ordId"` to track order status. Check `/api/v5/trade/order-history` for fills. Implement a kill-switch: if PnL hits -5%, cancel all orders automatically. Always set stop-loss at API level. **Risk Alert:** Without monitoring, a runaway bot can drain your balance in minutes. Use webhook alerts for critical events. šŸ”„ [Ignite Your OKX Trading ā€“ Lock Lifetime 20% Fee Discount with Referral Code: S123789](https://okx.com/join/S123789) šŸ”„ Trade smarter, not harder.
