Quote from InvestVision:
I am planning to buy the historical intraday data from this vendor given at this link below.
Has anybody used intraday data from this vendor , any input /experiences are appreciated .
disktrading has intra-day data from 1997 for ES for example, whereas IQ Feed has from 2005 only and esignal only from 2007.
Still, disktrading.com is extremely cheap compared to others. Why ? Is the data quality not reliable ?
