Quote from AAAintheBeltway:
I did this same research a few years back and, as far as i can recall, that was the hangup. With QCharts, I can blow up a chart across three monitors, go from 5 minute to 60 minute or daily bars with one click and have the entire contract's history. Trying to store a database on your computer or fiddling around with a download were not going to cut it for me.
Now I see that both Sierra Charts and Linnsoft R/T use alternative data feeds for historical backfill. Linn charges $15 a month for it, and sierra throws it in with their upgraded package. I suppose that is what ninja offers with its data service. If it is now as seamless as ESig or QCharts, it is hard to justify paying ESig's high fees.
Ah, thank you for sharing your insights.
I've sunk a lot of time into javascript so I could program my own efs and backtest the strategies into semi-mechanical systems, but at some point I recognize it's just a matter of re-educating myself in order to get the same result while dropping costs to 1/15th of what I'm paying now. $15 is nothing!
