I see. So best option, like you suggested, is to define them within a function so they are defined every new asset traded. Thanks

Fair enough. I have MQL4/MT4 on the brain. During backtests, entries are marked regardless of the trade outcome. A minor inconvenience but one that can be lived with/worked around easily enough.

Any ideas on the above log file entry? Or how to access the trade pool? Or should I start a new thread (or two) before this one spirals out of control?

Cheers,
