Hello!

Client contacted me and we managed to solve the problem. But let me explain here for the others if needed.

This indicator have prefix and suffix in inputs. Usually you can just add than in inputs, for this case instead of EURUSD pair is named EURUSDp, so you need to add suffix "p". If broker have multiple EURUSD pair names there may be the problem. You can still use this indicator in other broker demo accounts cause this indicator have multiple activations.
