Stop Loss Gap Requirement for ROBO Orders

[whemant]

Hello,

I am reaching out to understand the requirement for a significant gap between the order limit price and the stop-loss price for ROBO orders.

Here are the parameters I used while placing a SELL ROBO order for NTPC:

Variety: "ROBO"
Tradingsymbol: "NTPC-EQ"
Symboltoken: "11630"
Transaction Type: "SELL"
Exchange: "NSE"
Order Type: "LIMIT"
Product Type: "BO"
Duration: "DAY"
Price (Limit Price): "334.90"
Squareoff: "8"
Stoploss: "3"
Quantity: "6"
The order failed with the message:
"The gap between stop loss and limit price should be wider."

However, when I increased the Stoploss to 4 or 5, the order got executed. I believe a gap of 3 (~0.9%) is already sufficient, and requiring a higher gap seems unnecessary.

Could you please clarify why this high gap is required for placing ROBO orders?

Looking forward to your response.
