I am planning to buy the historical intraday data from this vendor given at this link below. http://disktrading.is99.com/disktrading/ Has anybody used intraday data from this vendor , any input /experiences are appreciated . thanks
I was looking through cheap historical data sources and saw this. Looks really cheap compared to other databanks like tickdata.com. Can anyone please share their experience about the reliability/correctness of this data. Thanks a lot.
No, but another option is to subscribe to IQ Feed and rip historical 1-minute data from their stream using QCollector. They also have tick data for the last 30 days.
How much backhistory is present in IQ Feed ? I am specifically looking for 1 min or even 5 min will do. I don't need tickdata as of now.
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 ?
