cdcaveman: what types of trading does this kind of detail make a difference, scalping? I trade options and i don't even day trade them
Yes, scalping or daytrading short time frames, when you often make 100 trades during RTH. If you look at user forums of some charting packages, like SierraChart or (probably) Ninja Trader, you will see mostly everyone talking about tick charts, number bars, tpo volume profile, bid volume / ask volume analysis, delta divergence, etc.
If you only trade option spreads then you don't really need tick data and all that staff, unless you are looking to improve legging-in into the wings of your condors, butterflies, and the like.
