QC has serious limitations...
QC is an extremely difficult system to use for the average trader (I'm comparing it to competitors products with respect to coding, flexibility and ability to live trade) Given reasonable investigation the data it uses for backtesting is questionable (they cut you off if you look at too much data) and most importantly it only allows you to back test and live trade on a small list of underlyings: good for Bitcoin and fx (I assume but don't know) but NOT for equities and listed securities and most futures.
