This fellow posted his tool on the IB TWS forum, freelance tools. It's on IB's website under freelance too. http://www.tradingsoftwarelab.com/jtwsdump/ No tick data saved but all the bar sizes you could want. Try emailing him for help. curt
Thanks guys I will look at Sierra and Ensign next week. jTWS Dump looks interesting too - cost is 79 Euro. whitster, it's good that you pointed out that IB data is not true tick. I was aware of that (and didn't they recently tweak the number of ms between aggregations?). Does TradeStation provide you with the bid/ask data you mentioned?
Can you please explain what you mean by "effective" tick data? I'm trying to figure out if I can use my IB data feed to get reliable tick charts.
