a trading model that I'm very interested in but never have really gotten into it too much is tape reading. What is the best way to learn this? I took about a week of downloading tick data. Everytime there is a trade, change in bid, bid size, ask, or ask size is recorded. I have done this with the OpenTick data feed and the (much better) Genesis data feed. However, I must say I ain't gotta clue what is going on. I know that the Trade comes after the change in the bid like for example if 500 shares are bought on the bid you'll see (5)20.20 * 20.25(10) (10)20.19 * 20.25(10) ---> s 500 @ 20.20 but, I can't put together ANYTHING. I dont know if it is the data I'm getting (I've heard the genesis data feed is good) or what, but I find it nearly impossible to sort through the data and come up with a story of what happened? Would watching any particular stocks be helpful? do I want to watch news stock? is there a certain type of stock that is easier for tape reading? is there is certain # of avg daily volume that you'd like your tape reading stock to have? just looking for some help thx
