====================== Chuck ; How far back in years does Esignal- Hyperfeed go on options data/charts; & what do you get for $ 5-10k per month??? Searched your link & am aware only of your 5 day charts.
I still use RealTick version 7.6 which uses ComStock data. I have also used RealTick version 7.7 which uses data from other than Comstock. I have found RealTick 7.7 to be faster than 7.6; However, the Comstock data has far more depth of fundamental data covering several years. I am very sad to see RealTick dropping Comstock for a cheaper data source.
