Reference: https://okx-demo.ferndocs.com/api/api-reference/trade/place-algo-order ## Authentication - `OK-ACCESS-KEY` header (required) — Your API key. - `OK-ACCESS-SIGN` header (required) — Base64-encoded HMAC-SHA256 signature of the prehash string. - `OK-ACCESS-TIMESTAMP` header (required) — ISO 8601 UTC timestamp, e.g. 2020-12-08T09:08:57.715Z. - `OK-ACCESS-PASSPHRASE` header (required) — The passphrase you set when creating the API key. ## Request ### Body (application/json) This endpoint expects an object. - `instId` (string, required) — Instrument ID, e.g. `BTC-USDT` - `tdMode` (enum, required) — Trade mode Margin mode `cross` `isolated` Non-Margin mode `cash` `spot_isolated` (only applicable to SPOT lead trading) Note: `isolated` is not available in multi-currency margin mode and portfolio margin mode. - Allowed values: `cross`, `isolated`, `cash`, `spot_isolated` - `side` (enum, required) — Order side, `buy` `sell` - Allowed values: `buy`, `sell` - `ordType` (enum, required) — Order type `conditional`: One-way stop order `oco`: One-cancels-the-other order `chase`: chase order, only applicable to FUTURES and SWAP `trigger`: Trigger order `move_order_stop`: Trailing order `twap`: TWAP order `smart_iceberg`: Iceberg order - Allowed values: `conditional`, `oco`, `trigger`, `move_order_stop`, `iceberg`, `twap`, `chase` - `sz` (string, required) — Quantity to buy or sell Either `sz` or `closeFraction` is required. - `ccy` (string, optional) — Margin currency Applicable to all `isolated` `MARGIN` orders and `cross` `MARGIN` orders in `Futures mode`. - `posSide` (enum, optional) — Position side Required in `long/short` mode and only be `long` or `short` - Allowed values: `long`, `short` - `algoClOrdId` (string, optional) — Client-supplied Algo ID A combination of case-sensitive alphanumerics, all numbers, or all letters of up to 32 characters. - `tag` (string, optional) — Order tag A combination of case-sensitive alphanumerics, all numbers, or all letters of up to 16 characters. - `reduceOnly` (boolean, optional) — Whether the order can only reduce the position size. Valid options: `true` or `false`. The default value is `false`. This parameter is only valid in the `FUTRUES`/`SWAP` net mode, and is ignored in the long/short mode. - `tgtCcy` (string, optional) — Order quantity unit setting for `sz` `base_ccy`: Base currency ,`quote_ccy`: Quote currency Only applicable to `SPOT` traded with Market buy `conditional` order Default is `quote_ccy` for buy, `base_ccy` for sell - `tpTriggerPx` (string, optional) — Take-profit trigger price If you fill in this parameter, you should fill in the take-profit order price as well. - `tpTriggerPxType` (enum, optional) — Take-profit trigger price type `last`: last price `index`: index price `mark`: mark price The default is `last` - Allowed values: `last`, `index`, `mark` - `tpOrdPx` (string, optional) — Take-profit order price For condition TP order, if you fill in this parameter, you should fill in the take-profit trigger price as well. For limit TP order, you need to fill in this parameter, but the take-profit trigger price doesn’t need to be filled. If the price is `-1`, take-profit will be executed at the market price. - `slTriggerPx` (string, optional) — Stop-loss trigger price If you fill in this parameter, you should fill in the stop-loss order price. - `slTriggerPxType` (enum, optional) — Stop-loss trigger price type `last`: last price `index`: index price `mark`: mark price The default is `last` - Allowed values: `last`, `index`, `mark` - `slOrdPx` (string, optional) — Stop-loss order price If you fill in this parameter, you should fill in the stop-loss trigger price. If the price is `-1`, stop-loss will be executed at the market price. - `triggerPx` (string, optional) — The price level that activates this algo order. Unit: same as `px` for the instrument. Which price feed is compared depends on `triggerPxType` (default: last trade price). Direction: for a sell stop-loss, trigger must be below orderPx; for a buy stop, above orderPx. Error codes 51046–51049 are returned for direction violations. - `triggerPxType` (enum, optional) — Trigger price type: `last`: triggers when any trade occurs at or beyond `triggerPx` — most responsive but vulnerable to brief price wicks in thin markets. `index`: triggers on the underlying multi-exchange composite index — stable, not affected by OKX-specific wicks. `mark`: triggers on OKX mark price — smoothed and wick-resistant; recommended for derivatives. `last` is the only option available for SPOT instruments. The default is `last`. - Allowed values: `last`, `index`, `mark` - `orderPx` (string, optional) — Price of the order submitted when `triggerPx` is reached. This is separate from `triggerPx` (which determines when the algo activates). Set to `-1` to submit a market order when triggered; set to a specific price to submit a limit order. Not applicable when `advanceOrdType` is `chase` (a chase has no fixed price). - `callbackRatio` (string, optional) — Callback price ratio, e.g. `0.01` represents `1%` Either `callbackRatio` or `callbackSpread` is allowed to be passed. - `callbackSpread` (string, optional) — Callback price variance - `activePx` (string, optional) — Active price The system will only start tracking the market and calculating your trigger price after the activation price is reached. If you don’t set a price, your order will be activated as soon as it’s placed. - `pxVar` (string, optional) — Price variance by percentage, range between [0.0001 ~ 0.01], e.g. `0.01` represents `1%` Take buy orders as an example. When the market price is lower than the limit price, small buy orders will be placed above the best bid price within a certain range. This parameter determines the range by percentage. Either `pxVar` or `pxSpread` is allowed to be passed. - `pxSpread` (string, optional) — Price variance by constant, should be no less then 0 (no upper limit) Take buy orders as an example. When the market price is lower than the limit price, small buy orders will be placed above the best bid price within a certain range. This parameter determines the range by constant. - `szLimit` (string, optional) — Minimum order size per execution. Only applicable to `smart_iceberg` - `pxLimit` (string, optional) — Price limit. Only applicable to `smart_iceberg` - `timeInterval` (string, optional) — Time interval in unit of `second` ake buy orders as an example. When the market price is lower than the limit price, small buy orders will be placed above the best bid price within a certain range based on the time cycle. This parameter represents the time cycle. ## Response ### 200 Successful response - `code` (string, optional) — Result code. `0` means success; any other value is an error code. - `msg` (string, optional) — Error message.
