Description
Renko chart is very powerful on trend analysis as renko chart filters noise. However, you can not see the detailed price movement inside each traditional renko brick. This indicator will plot renko chart on top of traditional chart. Therefore you will see the detailed price movement inside the renko brick. When price moves very fast, the renko brick is small, then price moves slow, the renko brick becomes big.
This indicator works best on small tick chart, range chart as well as small time frame of time chart.
Any question or suggestions, leave comments below.

Hello,
i prefer renko charts too. But i use them in another way.
http://fxpro.ctrader.com/c/MsJdn
http://fxpro.ctrader.com/c/SsJdn
i use the swings as Supply and demand areas. look picture. I use the supply and demand indicator by afhacker from algodeveloper.com (he is listet in ctdn).
My problem is i missuse his indicator. in candlestick chart i cannot see the zones. have to draw them manually. maybe you have an idear how to display only the turn arrounds?

afhacker did not post his code on the website, it's difficult to know how his indicator works. If you can find the source code for supply and demand, I may able to figure out and potentially integrate it with this indicator for better visualization.
Also, try range chart and tick chart, they are not time based.
