Symbol: BTCUSDT_PERP_BINANCE Study: ECIVwapV1.5 First, this appears to be isolated to my Historical chart on BTCUSDT_PERP_BINANCE. I have multiple intraday charts running the same ECIVwapV1.5 study in the same BTCUSDT_PERP_BINANCE chartbook and all are working correctly. For reference, All of my other CME/NYMEX/COMEX historical charts are fine display the ECIVwap1.5 study correctly. I have never had an issue displaying this chart/study before. Tonight I ran the recent update to take advantage of the recent fix to "The Z-Order of the windows also may not have been restored correctly when reopening a Chartbook or switching between loaded Chartbooks"--- big thank you for fixing this. I attempted months ago to explain this issue, but I think I was unsuccessful in getting my point across- it was tough to explain. Back to my ECIVwap issue. Following the update tonight, my Historical Chart with Yearly ECIVwap is skewed and unusable and I have included a screenshot. I have double checked all settings associated with crypto charts- Auto set from data feed to NO. I have tried "Delete Data and Download" and this does not work. I tried rebuilding the chart from scratch, but this does not fix the issue. I was able to add the standard Volume Weighted Average Price study to a historical BTCUSDT_PERP_BINANCE chart successfully. But this standard Vwap study lacks the extension features that ECIVwapV1.5 offers and I require. What can I do to fix my ECIVwapV1.5 study on my historical chart? Thank you for all your help |

We are not sure about this. We will have to look over the source code of the study to try to understand it.

We converted some of the data types to double from integers and floats. And this is what we see after the changes: https://www.sierrachart.com/image.php?Image=1787121562329.png There is more to do but this seems like it is working properly.
