Re: [amibroker] HELP !!! problem with multiple time frames...

[Evo1 <Evo1@xxxxxxxxxxx>]

Hi Tomasz,

Unfortunately, it does not fix the problem : the result is still inaccurate.
Please, take for instance the stock Tektronix (TEK, market : SP 500) and you will be able to check it by yourself.

Thanks in advance for your help,
Regards,

Hello,

 

There is no bug in AB.

The problem is in the formula.

You should type your condition INSIDE "inWeekly" part.

 

TimeFrameSet( inWeekly );

BwiH = ( (BBandTop( Avg, 20 ,2 )- BBandBot( Avg, 20 , 2 )) / MA( Avg, 20 ) )*100;
LLVBwiH = Ref(LLV(BwiH, 120),-1) ;

NivH = BwiH < LLVBwiH;

TimeFrameRestore();

NivH = TimeFrameExpand( NivH , inWeekly );

Hi Graham,

First of all, thank you for your help, it is very kind of you.
As regards the Multiple Time Frame function  (see code below), I do think there is a bug in Amibroker.

For instance, let's take the security Tektronix (ticker : TEK - market : SP 500) and let's display 2 charts (weekly and daily) :

1) On the weekly chart, the last time the condition were true it occurred on 11/18/2005. The most important thing is that this condition is true during 1 week (i.e. 1 bar).

2) BUT WHEN displaying a daily chart,  the condition is true during 3 weeks !!! (it spans from the previous bar to the bar after...).
In all, we have 9 arrows !!! (I used the "plotshapes").

Your help would be greatly appreciated,
Regards,
Evo1


==== Code ===============================

TimeFrameSet( inWeekly );

BwiH = ( (BBandTop( Avg, 20 ,2 )- BBandBot( Avg, 20 , 2 )) / MA( Avg, 20 ) )*100;
LLVBwiH = Ref(LLV(BwiH, 120),-1) ;

TimeFrameRestore();

NivH = TimeFrameExpand( BwiH , inWeekly ) <= TimeFrameExpand( LLVBwiH , inWeekly ) ;
