Thanks for the reply Richard,
I can confirm that the correct EAs are running on the correct charts and time-frames, on separate copies of MT5, both are demo accounts running on the same server, the mT5s are running simultaneously on the same VPS.
After re-filtering FX Blue and checking the MT5 demo accounts this morning, five or six EAs for USDJPY are showing no losses in one demo account, but show losses in the other.
