Unfilled order replacement question

I have some question about unfilled order replacement.(entry order)

1-Does it work if the intended entry order is a stop order,rather than a limitorder
? sometimes a stop order has reached trigger price but not triggered at IB as the market bounces back a bit immediately.

2--Can unfilled order replacement be used in SA mode?

3--In AA mode,if the entry stop order is not filled,will the exit order be placed?

Thanks

Hello joyjoy,

1. It should work for all the orders provided that the price (bid or ask, depending on the order) has touched the order level, but it has not yet been even partially filled.
2. It is a general setting for both AA and SA modes.
3. In AA mode, if this order goes through in MC"s internal engine, it would be possible to place an exit, regardless of whether the order was filled by broker.
