charts overlap

 
does anybody know if it is posible to place two charts over on another on metatrader (live) not printed. say line charts and can see both
 
yes, using an indicator you can overlay a larger timeframe on smaller timeframe, such as see 1H on 15M.

look at heiken ashi. it uses 2 histograms. In this case you will create a histogram bar every 4 bars on 00 hour for example.
use iHigh(NULL,H1..,iBarshift(....,time[i]) and iLow(NULL, H1,.. as high and low point of an indicator

need a little work to put it together.
