Have been using Esignal - compared to IB i can't say i've seen 20sec delays.... but on the other hand, now have IRD to compare it too....
Esignal euro feed has no volume in the charts, either minute or tick charts. My tick charts have no historical info at startup approx 30min before market open... and get no historical tick data for maybe 30 mins after the market opens, some time later you can then refresh the chart and the previous days tick data appears.
The time and sales shows how bad things really are..... (ps in the quote window you don't get bid or ask size either :eek: nope, not even level 1). You can notice trades going off in IB TWS and nothing in the esignal T&S or delayed a sec or two.... compared to IRD it's completely ridiculous... eSignal that is. Have emailed Esignal but no reply.
IRD seems pretty good - early days yet.... they currently offer Hong Kong equities only now, are looking into the HK futures apparently... that's on top of scads of other euro and more exchanges.
IRd also replied to an email with info on tick charts - a new version due soon will offer user defined tick charts like 21 tick bar charts etc.
ps remember seeing someone mention they don't supply data to US customers......it's realtick software so maybe the cost is too much lower

.... not that it's cheap.
