Consolidated Audit Trail (CAT) Error days 

Thank you to /u/Region-Formal who has first found this

In this monthly CAT update there is a very strange options spike going from approximately 1-5M errors per day to more than 1Billion error rates per day, on 7th of June 2024. Whether this is related to some sort of extreme options activity,  I am not sure. but these seem to coincide with large volatility days for certain stocks, for example GME. More digging is required to understand why.

CAT error rates from a gsheet - as always open in incognito mode , and do so at your own risk, just a general online safety practice: https://docs.google.com/spreadsheets/d/1qJJiwrN9MI-21A0b3ngICCk-93JAmuHs9D87HjJ4ALo/edit?pli=1&gid=1195590281#gid=1195590281

• Its also the day when gamestop was halted a whopping 17 times: and DFV streamed
  •  DFV stream and halts during live stream https://www.youtube.com/watch?v=U1prSyyIco0 , where he was late on purpose, price tanked and halted, and it halted during the live stream as well : https://www.reddit.com/r/Superstonk/comments/1dap8mm/dfvs_4d_chess_move_expose_the_manipulated_price/
  • and then it was halted when the scheduled stream was about to begin: https://www.reddit.com/r/Superstonk/comments/1daf576/they_halted_when_they_thought_he_was_streaming/
  • Relevant Halts Post. https://www.reddit.com/r/Superstonk/comments/1damer4/gamestop_gme_halted_17_times_june_7_2024/

this is far too many "coincidences for one day": 1000x error rates spike in options, record halts for a security for one day relative to previous days, weeks etc. more digging required. page will update as more resources are found

my attempt to start putting them all together: https://www.reddit.com/r/Superstonk/comments/1dl040z/ape_historian_it_appears_crazy_cat_day_errors/
