Changes in OI:
1) $NVDA 130c 7/11 now 80,000 OI. Likely a stock replacement type of trade.
2) Always consider the changes in OI.... or lack thereof. Someone asked me to checkout the $BBAI 7c July calls yesterday. Left it on the watchlist to observe the OI today. We do have a moderate change of +5,400, but after a session of over 12,700 volume I think I might want to see more than that. The numbers line up in a manner in which its possible that the volume was a round trip, but the contracts being assumed by another trader and held through the close.
3) $HD 330p 9/19 open interest increases after yesterday's opening flow. The increase in OI does not = someone bought a put. There are simply just this many more existing contracts out there. They can be opened long or short. In this instance leaning a 'sell to open' put.
4) Tracked this $AMZN flow since early August 2024. They took profits yesterday. 41.60 -> 70.93
