Traditionally, I opened an Excel file with VBA, with the help of which applications were placed and removed in 2008-2012. I still use it to get OHLC slices at 10:40 and 12:00. And just now I noticed that in the Closing column there are closing prices (the last before the evening auction) on the last day when it was used for trading: 07/11/2012. And in the By Current column. are the prices yesterday at the time of closing the file after 12:00 (this is how the scripts work). An interesting comparison is obtained, after all, more than 10 years have passed.
The remaining columns are not so interesting, since these are the positions of systems and the shares of instruments that have long lost their relevance.
