The Watchlist's Day Chart for CME Group Inc. (CME) is only displaying about half a day's worth of activity on 2020-08-12. Clicking on the chart reveals there was trading activities all day long.

Some quote history are not adjusted of splits.
see : https://finance.yahoo.com/chart/GIGM
The split occurred on 16 Dec 2015.

Whereas, for example the AAPL curve is corrected of splits.

The data you post is great! Thank you! Less speculative negative "news" and less negativity all around would be nice. Were here to invest not lose money on pessimism and hatred for one reason or another.

Someone is having a laugh. The UK stock prices didn't drop to zero Monday & Tuesday, so why is it showing that on all the UK stock charts!?!

The recent stock split of BAM-A.TO (Brookfield Asset Management Inc.) is not properly reflected in historical pricing on the charts.

fix gold chart shows zero as the low three times in march!!!

Please note that the daily data on Yahoo Finance chart for SPY on Thursday 9/5/19 is incorrect. The corrrect daily data range for that date is as follows:

Open - 296.79
High - 298.83
Low - 296,64 (*** Not 294.0 as shown on the chart)
Close - 297.62

StockCharts has corrected this error, but it still remains on Yahoo.

This error causes a significant false chart pattern used as reference for hundreds of traders.

The Yahoo data source for this chart is incorrect and needs correction!

The previous day close proce reported on the 1 month chart is off by one day. Consistently.

Please fix it. Thank you so much.

Please review your 2/7/2019 to 3/7/2019, 5 min Chart of HSI HK which has a huge price mistake to 0 point and affected all indicator caculations!

Your Trending Tickers, Most Active, Stocks: Gainers / Losers are rather useless, too much penny and junk stocks that have no real usefulness. Too bad because these could be very useful indicator categories. What you need to do with these categories is limit the results displayed to stocks trading over $10 and with average volume of at least 200,000 shares.

As of Sat 4/6/19, graphs were not updated to Fri 4/5/14

when I open full screen chart for 6 month view when the market is open, the chart price and the current price are not the same. The chart price does not update the today's price. This problem occurred few times before and the Yahoo specialist doesn't seem to know what is going on.

Your moving average indicator doesn't work. The moving average line is different for different timeframes. A moving average is constant irrespective of the period of time during which it's being calculated. This is an enormous, and frankly, extremely ignorant error.
