I would like to know if the Time & Sales Tape exist also for the Stock Options? ESignal don't have it as long I know, other public source for that,if ti exist? I ask this question, since recently I have meet a problem with ISE and in the futur I would like to have more tools for a discussion about trade priority. I could summarize the fact 1) I was the first in the book at the bid for over 2 hours, every trade have been did at the ask in this lapse of time; 2) Suddenly, some new bigger order arrived at the bid, for an upgrowing volume on the bid; 3) About 15 min later this order is filled before me; I have contacted my brokers for to resolve (with success) the case, but I would like a better protection in the futur against this kind of problem and the T&S with the market could be usefull for my support, it is possible? NOTE: The specialist have mentionned that ISE is fully electronic and not possible this kind of thing (but I was able to see that only because my broker give me information on the last trade (price& vol) for each market and that I was able to do the match, but for the futur do you have a tips for fight this problem?
