Multi Time Frame Renko charts
cross over of the lower time frame (box size) is the signal for buy/sell.
Selection between the ATR and traditional box size is done by user. If you go by the traditional box size you have to select the box size manually. So change some based on the price of the Currency (you can begin by 1/10 of the currency price).
Tips:
It can be used for scalping or a confirmation along with your setup.
in case of selection of the traditional box size, set the chart's time frame less than 1D.
