Help Using Commentary for Debugging [SOLVED]

Hi. I'm still new to MultiCharts and EasyLanguage. I tried searching for an answer and didn't find one. Here's the situation.

I'm trying to use Commentary for debugging bar by bar, something I don't think the print statement can easily do (tell me if I'm wrong with that, though). So, here's my code:

Code: Select all

variables: 	Close_GT_Yes_High( false ), 

			Close_GT_Open( false ), 

			Low_GT_Yes_Low( false ),

			BuyTrigger(false), 

			TriggerBarHigh(0),

			TriggerBuyPrice(0);



Close_GT_Yes_High = Close > high[1];

Close_GT_Open = Close > Open;

Low_GT_Yes_Low = Low > Low[1];



{Debugging Code}

If CheckCommentary Then Begin

	Commentary("Section 01: After Initial varible assignment / inspection", newline);

	Commentary("Current Bar Number: ", Currentbar, newline);

	Commentary("Close_GT_Yes_High: ", Close_GT_Yes_High, newline);

	Commentary("Close_GT_Open: ", Close_GT_Open, newline);

	Commentary("Low_GT_Yes_Low: ", Low_GT_Yes_Low, newline);

	Commentary("Section 01: End", newline, newline);

End;

This works great, except the commentary window displays the expected commentary statement 4 distinct times, and several statements have different values for the same bar number when that shouldn't be the case. See the attached screenshot.

Any idea why the commentary statements are shown more than once?

Thanks for your help.

Hello dwitkin,

It looks like you have IOG enabled for your signal.
Calculation on historical data. IOG enabled. Bar Magnifier disabled.
The script is calculated four times on OHLC of the bar...Source:How Signals are Calculated
That is why you have four expert commentary outputs.

You can add a condition to perform expert commentary calculation only on bar close:

Code: Select all

if barstatus=2 then begin

Here is the adjusted code:

Code: Select all

[ProcessMouseEvents=true]

variables:    Close_GT_Yes_High( false ),

         Close_GT_Open( false ),

         Low_GT_Yes_Low( false ),

         BuyTrigger(false),

         TriggerBarHigh(0),

         TriggerBuyPrice(0);



Close_GT_Yes_High = Close > high[1];

Close_GT_Open = Close > Open;

Low_GT_Yes_Low = Low > Low[1];



{Debugging Code}

If CheckCommentary Then Begin

if barstatus=2 then begin

Commentary("Section 01: After Initial varible assignment / inspection", newline);

Commentary("Current Bar Number: ", Currentbar, newline);

Commentary("Close_GT_Yes_High: ", Close_GT_Yes_High, newline);

Commentary("Close_GT_Open: ", Close_GT_Open, newline);

Commentary("Low_GT_Yes_Low: ", Low_GT_Yes_Low, newline);

Commentary("Section 01: End", newline, newline);

end;

end;
