To study market behaviour. Trying to figure out when buying pressure came, before or after release. There is a consistent print streak of the least possible amount of upticks following each other
There were periods of increasing amounts of trades but I see no dead or lull periods at all between RTH close and Globex close.
%% MOST likely; not much of an impact on large samples+ long term results[ Edit=or even a lot of short term trade$+ didnt vote after looking @ your chart,thanks]. In other words NVDA = less than 5% of QQQ\and 3.15% of QLD; so >95% and > 97% not much pressure off that NVDA. Another big possibility + you may have consider this up/trending bull market/ that would be common pattern. Front month NQ is a 56%% buy short on barchart.com/ 40% buy yesterday; helpful even though i never let those ratings control my trades on invest$
