Can you help me to check this issue.
I build XAUUSD in SQX131 and export HST & FXT to correct MT4 folder well I confirm.
After that I use proxy setting disconnect MT4 like your step

But, it always show the error "read-only can't open[5]" in attachment
Status changed from New to Fixed
But it only happen in XAUUSD, others FX can backtesting well. Even read-only.
