I found the pattern described below. I would like to know if anybody else can see it. It is visible in the NYSE historical data (January 2019 - September 2021) for NKE (Nike). In over 63% of cases, HighTradePrice achieved between 15:36:00 and 15:41:59 increases by at least a factor of 0.00095682334649 compared to HighTradePrice achieved between 15:06:00 and 15:11:59 on the same day. HighTradePrice is defined as "Price of the highest trade".
