Dear Imraan Sir,
I am able to fetch Renko chart. There is issue in high and low data values. Please see high and low value difference issues can be fixed. Candles data on Dhan Renko charts is correct and data of low is almost different then the one fetched through python code. Kindly do the needful.

Hi @Ganesh_Verma ,

Which instrument is the code referring to?

3

Options chart BAJFINANCE 24 APR 8900 CALL. Sir may be I am wrong in symbol name Brick size is 5 points. In renko green candle open and low used to be equal, close and high is used to be equal. In renko red candle open and high used to be equal, close and low used to be equal. Please see Brick Color is Green. High low and close values are equal. In case of red candle formed after a green candle i.e, .loc[-3] green candle high and close = .loc[-2] red candle open and high. Kindly check first four candles data only. 10:37 candle is red but low is not equals to close and 10:53 which is again red candle and low is not equal to close.

In renko candlesticks, 209 with timestamp 12:40 high= 395 and low =395 and close = 395 candle formed is green. It is not possible sir, in case of green candle it has to be open = low= 390 and high = close = 395 then it is a renko candle. All green candles have open = low, high = close. High=close=low all equal is not possible in renko green candle. When a red candle formed followed by a green candle ie .iloc[-2] its open = low and red candle ie .iloc[-1] its open = high all used to be of same value. Please check screenshot you had shared a green is marked by you. If you match the low=365 value on renko chart and the candle 226 timestamp. 12:37 low = 370 value fetched through python code. There is a differnce in value between chart and what fetched through code. Also see red candle value in case of red candle open = high, low=close, where as code fetched opn = high, low < close which is not possible in red renko candle. Hekinashi chart is also not fetching proper candle data specially during market hours. You can call me at 9356787469 sir to further elaborate you on this.
