Arina, I guess you need Limit entry with signal like "level X is broken".
You can try with ZZ at the moment or describe new signal.
Stop-limit orders will not be implemented to the EA, sorry. They are supported by MT5 only and very hard to understand and use.
If I remember correctly, in the early stages of CP, we used to use pending order and then moved to stop orders with current live set.
CP is capable of pending orders. May plz check.
