hi, whroeder1,

im not multipair testing.

just using same EA for different pairs.

So for example - EA closes correctly orders for GBPJPY, but it doesnt close for EURUSD. It closes correctly for GBPAUD.

so what can be the root for error?

code below does not "fix" to any pair..

MarketInfo(OrderSymbol()
