Cheaper will never be better
Success of a strategy depends on the quality of data.
If the data quality is not good, then how can the back-test results.
Some say I’m just starting, so will go with cheaper, once get good strategy will move to good one.
But with cheaper, he never going to get good strategy, so never move to good.
The cycle continues…
It seems amifeed has backfill for 90 days, which is okay for intraday data, but for EOD, I will require at least a few years. Do you know what I can do about this?
