stop loss on btst futures

I buy futures and sell them the next day. How would i go about and put a sl on theses orders? Do i have to use after market order?

If you are placing an order before 4.00 PM and 9.15 AM, it has to be an AMO.
You can use the regular order type if you are placing the Stoploss order during market trading hours.

Can I be used for futures as well? When I click on my position the only option i get is to exit

Obviously you can place an stoploss in futures.
