This isn't a Quantopian alternative, Quantopian let you write real code and automatically trade based on it. It also let you trade buckets of stocks, not just one.

This is just a very basic strategy backtester, there are plenty like it, you can find them if you Google "technical backtester" and some of the brokers (e.g. TD Ameritrade) even let you do such backtests in their platforms (e.g. Thinkscript, though that's a tad more Quantopian-like than this tool).

If you want a _real_ Quantopian alternative, look at QuantConnect [0]. Interestingly, it's .NET based and you can write C#, F#, Python or whatever you want.

And the trading engine is open-source [1] and you can run it yourself.

Hence the comments on adding a lot more stuff.

I know it's not Quantopian right now but quantopian also started with a simple backtester which they then expanded quite well. I figured if there's enough interest, I'll just add on top of that idea and create something similar where you can backtest both with code and with just the UI.
