Bars == NULL

[oferr]

Hi,
I develpoed a small indicator that works fine.

At the indicator I am checking if (Bars==NULL) before doing any operations on Bars.x

Now, I am trying to develop a strategy based on this indicator.
I see that when the strategy is calling the indicator I always get Bars==NULL (I see it by debugging print at the output widow)

Can you help please why does it happen?

thanks,

Not sure I follow. Bars != null, *always* true in OnBarUpdate().

Hi Dierk,

The indicator I wrote works fine (Bars != NULL)

At the indicator's Init:

Print("my indicator: before");
if (Bars==NULL) return;
Print("my indicator: after");

and I do see "my indicator: before" and "my indicator: after" at the output window.


But...
I wrote a simple strategy and wanted to use this indicator.
At the strategy Init - I wrote: Add(my_indicator);
And I activated the strategy.
Looking at the output window I see:
"my indicator: before"
but I don't see "my indicator: After"

I asumme that Bars==NULL is the reason.

When the strategy is calling the "onBarUpdate" of the indicator, any attempt to read from "Bars" fail.

any idea?

Thanks.

You should not access "Bars" property in the Initialize method. Please redesign your logic accordingly.
