The problem with tape reading is:
-
you can't tell if someone bought or sold the option (unless it was executed at the bid or ask)
-
you can't tell if the trader owns the stock or is short (buying a huge amount of puts could actually be bullish if it's just a hedge and they're long)
-
you can't tell if it's opening or closing a position (a large buying of puts could be someone closing previously shorted puts)

November 22, 2021Is real time data required for options trading?
