Is there a video somewhere of the actual talk?

The "Hello World" sample algorithm on Quantopian gets a 4000% return if it operates on AAPL for a year. It makes trades each minute using a "3 day volume-weighted-average-price." I find it hard to believe this algorithm would perform so well in the real world.

How much of an impact would factors like latency in a real world environment have on this algorithm?

Thanks for the tip. Looks like they have a 10k minimum balance.

If you decided to use an algorithm for real-world investing, what brokers would you recommend that have good APIs?

True, but Amazon probably makes close to a billion in annual revenue in CA, I feel like that must account for some kind of taxable "presence."

I wasn't aware anyone actually declared their Amazon purchases at tax time.

With 2 day shipping through the prime service, they pretty much emulate a local retailer. The prices are awesome but I can see how their tax advantages give them an unfair advantage on local competition.

clever advertising if that's the case
