Help with EA order trigger

Hello,

I have been testing this EA for the BAT system(by Team Aphid) coded by fukinagashi and have noticed that buy orders seem to trigger when the ASK price hits the upper BAT indicator line. My understanding of the BAT system is that long entries are taken when the BID price hits the upper BAT line.

I have tried looking at the coding of the EA to determine what triggers the buy order and at what level but I can't quite figure it out.

I would greatly appreciate it if someone could take a look at it and advise how the EA determines when to send a buy order and how to modify it so that it enters long only when the BID price hits the upper BAT line.

Thanks,

CFII
