$SPX Insider selling Part 2 before and after EU open

Ok, So I made some changes to the script and now trackingthe ALGO behaviour before and after European open. So far, my study sugest, large sell volume is getting distributed before the US market open. EU open did not change the ALGo even though DAX was down more than 3% and there was an announcement about the virus that should have affected the ALGO. So my conclusion is large volume is getting distributed that must have activated ALGO Sell slice routine and since computer programs are binary, they can only follow one instructions.

Note: All of the above is my conjecture based on pure behaviour of the price action and clues form my scripts.
