Dear sir

I trade by using Renko chart in MT4. It is generated by drawing candles in offline chart.
All of indicators can be applied normally in this Renko chart ( is is commercially bought from Ovo).

But this one was not drawn properly. There is only blank window under main chart.

I tried to explore and modified some things, but it didn't work.

Please point me out the causes of this problem.

Thank you.
