i had one year pack of viratech ( which soon goin2 expire ) so experimenting with 3 months subscription of market-data-provider ( 3k for 3 months ) so far its ok considering its low cost ( though l2trade forewarned me about its bad service lets see)
Though this is not the proper forum for the discussion on the data providers, but I think you need to be beware of market data provider as Alex has also mentioned in his post. The service is pathetic and worked only 50% of the time for me.
