Hey @Ameebha_D ,

To place a buy order above the market price, you can use the triggerPrice parameter. In this case, the trigger price should be lower than the price you specify.

Also, please ensure that the orderType in the payload is set to STOP_LOSS instead of SL.

Below is a sample payload for placing an order above the market:
{
“dhanClientId”: “xxxx”,
“transactionType”: “BUY”,
“exchangeSegment”: “MCX_COMM”,
“productType”: “MARGIN”,
“orderType”: “STOP_LOSS”,
“validity”: “DAY”,
“securityId”: “472783”,
“quantity”: 1,
“price”: xxxx,
“triggerPrice”: xxx
}

You may test this request structure in our sandbox as well Dhan API
