I was using viratech data it was fantastic, I did not know what the difficulty was on fetching data. I came across ISTOCKSYSTEMS, it was fairly cheap. The thoughts of saving moved my mind. I subscribed to istock & bought with that the best mental disturbances and torture I could have with the discount.
Very poor product, 100% not worth the price. Too demanding on your PC, takes lots of time to load. Regularly meets with server problems. Just 2 days back was there a problem with their server and data feed stopped.
They promised changes months back and that month is approaching at snails pace. My experience, pay a price but still chose the best, buy peace of mind with anything you buy, may it be data, shares or for that matter even your shoes.
