hey damo.... to do that most likely would involve the use of ms excel..... the high and low are the same but open and close heikin uses are different than standard open close data values supplied to us..... and of course those standard data values is all meta has to work with unless we supply more.... you could create an expert but experts can't create candlesticks.... you could however use excel to calculate the heikin values and then use that modified data to create a true hiekin chart..... are you handy with excel..... might be a good thought to put on the wish list..... that being 5 vacant but user definable columns in the metastock data sheet, where we are allowed to select which columns to plot..... the more i think of it the more applications come to mind......h
