Super Order jumped, price not triggered

I create a position by clicking BUY at Limit Order.(Not a super order)

  1. My understanding is that this order is sent to exchange the moment I hit BUY and when the limit price is hit , the order is executed.
    Now I have a have a position open and want to place a Stop Loss Order.
  2. Is the Super Order only way to place Stop Loss Order ?
  3. Is the Super Order only on Dhan Server and sent to exchange when the trigger price is hit ? (one side or both as the case may be)
    If yes, I think there should be an option to place a normal stop loss order with trigger and limit price.

If separate stoploss orders can be placed for same position(others brokers have it) , that is great feature.
Separate Super Orders for same position also can be helpful ( Different stop losses). Once placed, the Super order quantity can’t be changed. Why ? Let the user decide the quantity. Software/App should show and restrict maximum qty.

My Super order was jumped when there was a sudden price change. This can happen but the chances of failure are less for a normal Stop Loss order than software/app based.
Please correct me if I am wrong.
One more suggestion is to display the LTP on closed orders page too.
