Backtesting......... !!

What has been changed in the last few updates??
ALL my coded cBots, new and old (3.0) return the message (below) when I try and backtest any (even slightly) altered algo's.
BT Log: Crashed in OnStart with NotSupportedException: Chart operations are not supported in optimization
Starting to have one too many issues with memory usage as well.... absolutely strangles the CPU.......

Thanks Panagiotis..... My apologies.. It was text that displays on the Chart. I'm sure this is a new phenomenon, my code has contained txt print commands for over 7 months.
Another error that is new coming up is the one below....
BT Log: Crashed in OnStart with ArgumentException: Incorrect parameters count. Parameter name: parameterValues
I seached the Ctrader site for a fix for both... very little info on error codes, statements, maybe something that can be added.
Thanks in advance Panagiotis

Hi Symposium,
This error comes up when you have a custom indicator and you pass the wrong number of parameters to the constructor. Can you please check your code?
Best Regards,

Hi Symposium,
As the message indicates, you are probably using chart operations in the cBot e.g. drawing objects on charts. These operations are not supported in optimization.
