Re: [amibroker] Why does it take so long to apply edits?

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Dennis,

If you are "applying" the code - it is for the first time executed
with ALL bars, regardless of QuickAFL and SetBarsRequired settings.

Now *if* your formula is complex and uses looping and you are using
for example tick database with hundreds of thousands of bars
it may take a while. Usually it is non-issue as people are not using such complex formulas.
(1 second is *very* long for execution under normal circumstances.
My formulas usually execute well below 0.1 sec).

You may wrap your code into

if( Status("action")==actionIndicator)
{
...
}

and this will prevent this effect.

Best regards,
