Subject: [amibroker] Confusing Behaviour...!!!
> Hi,
>
> I'm trying to get some code to run as fast as possible. As such I've
> been studying the 'Display Chart Timing' option under preferences>misc.
>
> I've noticed some behaviour that I can't explain. I hope others may be
> able to.
>
> Firstly I notice that when my chart requires 10,000+ bars I start to
> notice latency in AmiBroker, despite running a very fast PC. I assume
> that is normal at that number of bars...?
>
> So here's the problem...
>
> Under normal circumstances my code requires 297 previous bars.
>
> However, If I add the following lines, the number of previous bars
> required increases by 5,000 for each instance. So after these three
> lines of code I am now needing 15,297 pervious bars.
>
> H1=SelectedValue(TimeFrameGetPrice( "H", inDaily, -1 ));
> L1=SelectedValue(TimeFrameGetPrice( "L", inDaily, -1 ));
> C1=SelectedValue(TimeFrameGetPrice( "C", inDaily, -1 ));
>
> Even stranger, when I add the following line of code into the main
> body of code,
>
> test=((BarCount - 1) - LastValue(TroughBars(L, 0.05,10)));
>
> It adds 500 bars to my previous bars required (total new 797).
>
> However if I call a function and simply return the following,
>
> return ((BarCount - 1) - LastValue(TroughBars(L, 0.05,10)));
>
> It now requires 5,000 previous bars instead of the 500 outside of the
> function (total now 5,297).
>
> Can anyone explain this behaviour...?
>
> Many Thanks
