OnTimer() x backtesting x Visual Mode

For more than one year I thought (because I swear I have read on some help place) the OnTimer() event would not be triggered when using backtest or optimization at all.

Ok... I use the OnTimer only to write some stuff on the chart.

Then, because of a OnTimer crash error related to API.Color (version 3.01) x Colors (version 3.0) when backtesting, I added a get away code: if(IsBacktesting) return; in the beginning of the event.
And the backtesting speed (as optimization as well) increased a lot.

I think it should be noticed CLEARLY in some place in the Help information that the OnTimer event is always triggered and only the chart drawing is not displayed because of obvious reasons.

-------> Now, I think it should exist a IsVisualMode similar to the IsBacktesting property because if the code does something relevant to the robot you want it to run, but if there is also something being written in the chart, you do not want it to run.
