IB is not tick by tick but if you use IB then you can use IB data feed to Sierra or Ensign or Quotetracker with IB data. With backfill it is now really not that much different from a regular on demand feed. All are very reasonably priced with excellent service (i.e. the OPPOSITE of my eSignal experience). I use Sierra and QT. Ensign customiseability looks nice and I know the service is good but the individual data storage time untit configurations put me off.
If you don't use IB then Asian markets are difficult and expensive. As far as I am aware CQG does not carry Asian markets (maybe SGX?). Its basically S&P comstock, Reuters or BBG. DTNIQ carries the SGX. You could also look at Nextview or Quotepower. Futuresource is now part of Esignal. Esignal never worked properly for Asian markets anyway, no tick chart for HSI, excruciating lags in T&S, data completely corrupted for another market. I dumped them. If the product actually worked properly, was reasonably priced and 'blame the customer' strategy for customer service was addressed it would be a useful product.
