OCO Orders

Stop-loss + target bracket pairs, and adjusting a position via the option chain.

Stop-loss + target pairs — SL and TP legs that cancel each other once one fires.

hasOCO

Whether the broker supports OCO (One Cancels Other) orders. false disables target/take-profit order placement entirely — everything on this page becomes unreachable from the chart's own UI.

bool get hasOCO => true;

placeOCOOrder / modifyOCOOrder / cancelOCOOrder

void placeOCOOrder(String params);
void modifyOCOOrder(String params);
void cancelOCOOrder(String groupId);
void groupAdjustOrders(String params);

placeOCOOrder/modifyOCOOrder params:

{
  "side": "buy", "productType": "normal", "stopPrice": 2350.0, "stopQty": 10,
  "symID": "RELIANCE", "targetPrice": 2450.0, "targetQty": 10,
  "targetTriggerPrice": 2440.0, "groupId": "OCO001"
}

Field	Type	Accepted values
`side`	`String`	required; `"buy"` / `"sell"`, case-insensitive
`productType`	`String`	required; `"normal"` or `"intraday"` — top-level, not nested per leg; both legs of one pair always protect the same position
`stopPrice`	`double`	required; stop-loss leg price
`stopQty`	`int`	required; stop-loss leg quantity
`symID`	`String`	required; the symbol
`targetPrice`	`double`	required; target leg price
`targetQty`	`int`	required; target leg quantity
`targetTriggerPrice`	`double`	required; target leg trigger price
`groupId`	`String`	optional on `placeOCOOrder`; required on `modifyOCOOrder`

cancelOCOOrder's groupId is the plain string, no leg data needed.

groupAdjustOrders params — simultaneously exit held legs and add new ones from the option chain:

{
  "exit": [
    { "action": "Buy", "id": "NIFTY2560023000PE", "ordType": "market", "price": 120.5, "quantity": 50 }
  ],
  "add": [
    { "action": "Sell", "id": "NIFTY2560024000CE", "ordType": "limit", "price": 85.0, "quantity": 50 }
  ]
}

Field	Type	Accepted values
`exit[].action` / `add[].action`	`String`	required; `"Buy"` / `"Sell"`
`exit[].ordType` / `add[].ordType`	`String`	required; `"market"` / `"limit"` — a smaller set than `placeOrder`'s `orderType`, no stop variants
`id`	`String`	required; the option contract's symbol id
`price`	`double`	required; leg price
`quantity`	`int`	required; leg quantity

exit — exit legs for currently-held positions (action inverted from the position side, e.g. a long position exits with "Sell"). add — new entry legs selected from the option chain.

ocoOrdersStreamer

Pending trigger pairs only — SL+TP legs not yet real orders. Once a leg fires, the broker reports it on ordersStreamer instead, as a plain order.

Stream<String> get ocoOrdersStreamer;

Must be a broadcast stream.

  {
    "groupId": "OCO001", "symID": "RELIANCE", "name": "Reliance Industries",
    "exchange": "NSE",   "side": "sell",       "productType": "normal",

  }
]

Field	Type	Accepted values
`groupId`	`String`	required; the pair's own identifier
`symID`	`String`	required; the symbol
`name`	`String`	optional; display name — note the key is `name`, not `displayName`; falls back to `symID` if omitted
`exchange`	`String`	required; exchange identifier
`side`	`String`	required; `"buy"` / `"sell"`, case-insensitive
`productType`	`String`	required; `"normal"` or `"intraday"` — top-level, shared by both legs
`stopLoss` / `target`	`object`	required; one `OCOLeg` each (see below) — both always populated; there's no unpaired form

OCOLeg shape (used for both stopLoss and target):

Field	Type	Accepted values
`type`	`String`	required; `"stoploss"` or `"limit"` — lowercase, same values as `Orders`' `type`/`orderType`
`side`	`String`	required; `"buy"` / `"sell"`
`triggerPrice`	`double`	required; leg trigger price
`qty`	`int`	required; leg quantity
`price`	`double`	required; leg price
`fillQty`	`int`	required; quantity filled so far, `0` if none
