During back testing everything works fine. No error messages and all trades show up normally.

When I let it run in my IG Markets Demo account that’s when the system was stopped with this error message. It seemed random because I also had many trades that were executed normally.

Some systems were stopped after a few minutes or a few hours and some not at all so far.

I  set up 21 Algos in my demo account using 7 FX pairs (EURUSD, GBPUSD, AUDUSD, NZDUSD, USDCHF, USDCAD, EURGBP) and 3 timeframes (10m, 15m 30m). So it’s 21 times the same system.

The systems are made for Forex (non JPY pairs). You wouldn’t be able to get any trades on DAX or DJI).
