i have just ditched e-signal. i trade futures and just couldnt put up with it any more - it started to cost me money in terms of missed opportunity. when it does work, the feed is fast and accurate though. couldnt comment on stocks - most seem to think its ok.
real tick. never used it, but i know people who have and they dont seem that impressed.
im currently using iqfeed (
www.iqfeed.net) it seems rock solid so far. for trading us index futures, you are looking at around $80-$90 including exchange feeds, but you also need a chart application like
www.sierrachart.com , quotetracker.com, metastock, tradestation etc. the best is probably
www.ensignsoftware.com
www.prophetx.com looks very good, and costs around the $200 mark with data i think. you must cotact them to get a quote. its also from the dtn data plant (like the iqfeed) so should be rock solid. i will take a trial next week.
take a look at the reviews on elitetrader.
