Eric,
point is that if you are in the Daily timeframe you want the MA14_Weekly array to be expanded to the daily timeframe.
This is why I added in the second Email:
Buy=Cross(Close,TimeFrameExpand( MA14_Daily, inDaily )) AND Close > TimeFrameExpand( MA14_Weekly, inWeekly );
Here you see I also expand the MA14_Daily. If you are inside the daily timeframe it will not change your array. However if you are in the hourly timeframe both the MA14_Weekly and the MA14_Daily will be expanded to the hourly timeframe,
rgds, Ed

why do we need to use timeframeexpand()? Does ma14_weekly already have
weekly data?
Thank you
