Can you elaborate? When I compare tradestation data to IQFeed it's usually identical.

I understand, however not everything is a result of speculation as such....depending on how you define this of course. I give you kudos for what you are doing, I just feel that you need to be very clear in what is included, and ultimately it is next to impossible to tell the reasons for the trades.....but maybe this is not the point.....

eg; speculators are trading in nat gas, and the hedging type market makers decide to hedge/spread in the crude market, and the heating oil market.
eg; a long term holder of an equity (say a bank stock) always sells calls against their holdings every two months, and either rolls these calls or sells them against their holdings each time. the market makers generally buy these calls and to hedge in their books sell the underlying stock.
eg; a client requires an average price swap over the period of a week in a particular instrument as part of a portfolio, and sometimes the averaging of portfolios - depending on the exchange reporting requirements - see these prices be executed at close to but not exactly within the market, in order to report the entire portfolio at the one time.

unfiltered data means u will be able to see bad ticks outside the bid/ask spread hititng less than 1 second. filtered means getting rid of the bad ticks. some platforms have unfiltered data some have not. the worst of having an unfiltered data is it freezes the computer because too many data flowing into the computer.

so it sounds like filtered is a good thing.

Thanks for the explanation.

I am still unsure as to how these trades happen. I think trades should not be allowed if they don't go through the order book.

I also have become doubtful about this ! Could trades actually occur without going through the order book ? Is it possible ?
