The above is my latest go at trying to get this thing to work I'm just glad I don't rely on this for a living.

Right; so you have changed the OrderSend call, now attempting with "3" as stoploss instead of slippage. A mistake I guess in some re-write or experimentation? Maybe revert back the OrderSend arguments to how they are in your first posting?
