Quote from: Sacha on June 01, 2026, 01:57:27 AMYou are right about the problem. Even using yfinance gives the wrong output.
We are investigating it.

Thank you for reporting about the problem. We hope to fix it soon.

I really appreciate your attention to this matter.

Would be great if you can keep us posted.

Donno if yfinance api guys have any support team ...If so you may connect with them and get this sorted

Till then we can use other sources in the list.

Check out 20th April 2026 candle of SBI (NSE) in Stockalyze and Yahoo finance and all other platform.

https://share.stockalyze.com/u36z6v




Stockalyze is showing wrong candle data .I m not sure why this is happening becasue I have other tools using same yahoo finance API and giving correct data.



Scanning , backtesting and all analysis will be wrong if the data is skewed

From yesterday its showing correct data , but many many previous candles have been printed with wrong OHLC data in ITC and all other stocks in stockalyze

Quote from: Sacha on May 28, 2026, 02:20:46 AMNo. It wasn't showing in yahoo finance, please check the image I had sent.
Anyways, as of now the data is available in the yahoo finance and so also in Stockalyze.

In my stockalyze its showing same wrong data. Many candles are showing wrong data .

Check 1st Jan 2026 long candle . 29th april OHLC data of ITC  ....all its wrong data in stockalyze but correct in yahoo finance , TV, and all other platforms

May be the python library that is used to fetch the data is enriching wrong data. I checked across Log and percentage and all other formats .Mostly all presenting wrong info in stockalyze .






I checked in motivewave desktop app now which also fetches from Yahoo finance API. Motive wave is showing correct data.


Please please have a look at this .


This needs to be investigated

Super Awesome and Thanks a ton for this :-)

Quote from: Sacha on May 27, 2026, 02:41:32 PMStockalyze uses data as is from the data provider. If the chosen data provider doesn't have the data Stockalyze cannot do anything about it. I just checked Yahoo finance also doesn't show the candle for 27 May. See the attached image.

27th may data is showing correct in yahoo finance website and showing wrong data in APi fetched quotes. [screenshot in link]

API fetched quotes are showing wrong data overall in many dates for ITC...Yes Stockalyze cannot do anything about it ...It was a general query. Because this can result in wrong backtesting data and wrong trades.
