difference between using the: if(bInit == false){} & nState

[waynecd]

Hi,

Is there a difference between using the: if(bInit == false){}
vs using the if (nState == BARSTATE_ALLBARS) { }
as I understand it both are limited to "the bars are being loaded by the script".
Thank you for any help.

Yes there is. See my reply and example posted in this thread

Thanks Alex,

I'll study your sample script. I am trying to reduce eSignal lag by programming more efficiently and eliminating redundant/unnecessary calculations.

It seems that BARSTATE_ALLBARS may be more efficient since it doesn't compound at each refresh. (not sure I know what that implies yet but it will likely be more clear once I study your example.

Thanks again.

Hi Alex,

1. Does a study initialized in the bInit routine compound when the chart is refreshed via Ctrl+OK or only if it has a sum statement like the "Counter++" statement in your example?

2. When if ever is it appropriate to initilize a study (built-in or custom) within the "if(getBarState()==BARSTATE_ALLBARS){" statement as opposed to the bInit routine?

3. Do you have a link to tutorial 5 (Accessing Chart Data). It is referenced at the end of Tutorial 4?

Thanks Alex, help from the forums make a huge difference.

Again review the post I linked in my previous reply

To my knowledge Tutorial 5 does not exist. As a matter of fact I believe that the reference you mention was removed from a subsequent revision of Tutorial 4
