ctrader sample bot multiple instances

cTrader has inbuilt cBot 'Sample RSI cBot'.  I also added SL TP to code.

If I run multiple instances of this cBot (same symbol, different timeframes), it shows same Label 'SampleRSI' for all positions opened through different cBot instances.

This creates problem because bot can't differentiate which open position need to be closed.

How can I add new parameter 'Instance_Name' to cBot?  It will allow me to write different values in Instance_Name parameter for each cBot instance, to differentiate open positions.

I am not expert in coding, so please update it in the below code.  Thanks
