Thank you for your reaction. I asked OANDA for a reaction and I think they blame MT5 for being unable to test Galileo FX settings for stocks/shares (not CFD's) in MT5 and being unable to trade them. Here's their reaction:
"I received information that it is possible to connect various robots to MT5, but you need to know their specifications. If you need API for the Galileo FX unfortunately, you won’t be able to connect it. Additionally, if the robot is not written in the MT5 language (MQL5), you won't be able to connect it either.
I hope this answers your question."
This is getting almost too complicated for me...
