So I may be able to help. I had this set up for a few days with no help and could hardly get it to place a trade let alone any profitable ones.
I now have it running and making 40%+ in its first day.
The key things you need:
A fast VPS - mines a 4 core, 16gb RAM from VULTR. This is located in London (important).
A fast quotes feed - I use the WesternPips Trade Manager 3.7 and its own LMAX source. As LMAX are based in London it means I have very low latency on my quotes (around 2ms)
A RAW broker account - My current demo account is with EightCap (same as FCFF)
I have attached a screenshot of my settings for GBPUSD. More can be provided.
