It would be very interesting to see the chart of actual trading next to a similar chart generated by the Quantopian backtester.

Very impressed with the product btw. Good work.

That's a great question, I've been working up a more detailed analysis of implementation shortfall (and thinking about ways to make this automated) - but your question prompted me to post a quick comparison here that you can look at for some current results: https://www.quantopian.com/posts/live-results-vs-backtest-re...

Full disclosure, I work for Quantopian and I wrote this strategy.
