This indicator allows you to draw higher TF candles in the price window.The period of the high TF candles is set in minutes (1 Hour 60, 4 hours 240, one day 1440 etc.)
The high TF candle is drawn as red or green rectangle. As it is not possible to fill a rectangle with color I just added a series of segments to “fill” the body of the candle.

The Heikin Ashi version is available here: Higher time frame Heikin Ashi candles on a lower time frame chart
