The MT5 EA build through the SQXbusiness couldn't publish to MQL5 website. It show "Same as main chart" is not a symbol.
The MT5 EA are using multiple subcharts and SymbolSelect is the part caused the problem.
Temporary solve for me is comment out the SymbolSelect in the file internal/extend/Code/MetaTrader5/mt5Parameters.inc
I did this because the subchart I'm using is the same symbol but different timeframe. So, commenting out the SymbolSelect doesn't cause me any troubles. I know this method make me to edit file that I shouldn't edit on but I don't have other workaround for me to build and publish yet.
Thanks
