The image I uploaded is NOT a correct representation of 5.23.25 SPX price action and if you compared it to CBOE data it most certainly would NOT match. It should be pretty straight forward if you compare the image uploaded in my 1st post to the image uploaded in my 2nd post (revised chart 2nd image). You will see the 5.23.25 spx_cgi daily candle (1st image) is mis-representing price action as a doji with and opening price of 5840. Here in my response, I have uploaded the (revised) spx_cgi chart being displayed on sierra with the 5.23.25 daily candle showing a gap lower with a 5781 opening price. The latter image included in this response post is represented correctly and thus would match CBOE historical data. So yes, it has since been revised. The method you used of comparing CBOE historical data to the revised chart would not provide you with an accurate description of what is persisting to happen during live trading. The chart is not left displaying mispriced data it gets revised. While this revision is expected/appreciated, the questions I presented were in reference to the root cause of the data malfunction, if it is preventable by the user's settings, or if it is a data feed issue from the supplier. Furthermore, these discrepancies are happening during market hours, not post market just to be clear. And just to revisit the 5.13 instance both daily and intraday charts were affected. Friday 5.23.25 the intraday smaller time frame charts were correct, and the daily chart was malfunctioning. I took the liberty of listing the chartbook windows and described my computers specs in order to examine the possibility this is being caused by user overloading the platform. If what you see in terms of specs and chartbook descriptions is acceptable, can you please advise on what is going on here with the candles mispricing the index repeatedly during live trading.
