Hi Steve,

1) I want to display on a daily chart the lowest level of the weekly bandwidth (over 120 periods). On the  weekly chart, it corresponds to the green candle (see screenshot below)
Its code is :

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

2) In order to check the sync on the daily chart, I use the following code :

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 );

In the screenshot, you can clearly see that the result is false : the green arrows (daily chart) are not in sync with the green candle (weekly chart).
You can check it by yourself : in my example, I used Tektronix, ticker TEK, market SP 500.

Thanks for your valuable help
Regards,

Sorry Evo, guess I misunderstood...

 

Looks like your trouble may be use of Ref() function? I think it will shift the array by one bar in both timeframes, removing a week's worth of data in one case but only a day's worth in the other, causing loss of sync. You could try using Ref( ...,-5 ), but then there are the 4-day weeks...   Or you could try expanding the weekly bars before operating on them....    What exactly are you looking to do?
