Multileg Option order execution

Hello So I want to start vertical spread and I was wondering how people execute this Order on entry and Exit?

I had incident in past when I tried to close my 2 leg on closing with 2 limit order and my short option did not closed and next day need to take big loss as market move against me

is market order is only way to go and accept slippage? or we have any other option?

try SENSIBULL

they are only creating 2 limit or market order. if I am not wrong which you can do with basket order on kite
