i tried prosuite 2000 with several quotefeeds, because i was looking to find the best solution for me. here´s what i found out:
1. esginal: the most stable an reliable feed. big advantage is that esignal feed is supported by omega and you dont need an extra connection between feed and prosuite. disadvantages: it´s the most expensive feed and you have symbol restrictions.
2. RT3 with dynastore for TAL (for further information see
www.dynastorelight.com): almost as good as esignal. no symbol restrictions, feed is free if you use a RT3 broker and do enough trades per month. only one-time cost for dynastorelight, which is really worth the money. i compared the feed during the first hour of trading with reutersTerminal quotes - no difference (had radarscreen running with 500 symbols at a time). but if rt3 is down - your ts feed is also gone.
3. quote.com with dynastore for qfeed: advantages: no symbol restrictions, cheapest feed ($92 / month including exchange fees) if you dont have a rt3 broker. disadvantages: big lags (although you have the server selector that shows the current status of all quote.com servers it is not that easy to keep in running constantly), comparison reutersTerminal - qfeed (again radarscreen 500 symbols) showed a delay somewhere around 10-20 secs.
------------------------------------------------------------------------------------
i do a lot of realtime/eod scanning and thats why i have so many symbols connected.
if you can afford it and you dont happen to use a rt3 broker you should use esignal. if you already use rt3, do yourself a favor and buy dynastore for TAL - it´s almost as stable & reliable as esignal but a lot cheaper as you only have one-time costs.
qfeed - do it on your own risk. in the period i used it (for ab 2-3 months) i stopped counting the crashes after the second week....
