Real money, invested with algorithms

Some other commenters have hinted at this but... I feel sad whenever people build this kind of stuff. It&#x27;s probably a very well built product (or will be) and is better than the alternatives out there, but the unfortunate fact is that anything that enables and encourages active trading in modern financial markets is setting 99% of their customers up for failure. And the 1% that are actually on to something will quickly move off the platform onto their own, or will end up losing whatever they make when their strategy loses whatever alpha it has and they can&#x27;t admit it (I&#x27;ve seen this happen, but never the former, actually).<p>Trading is hard. I run a proprietary trading firm with modern technology infrastructure and we have a lot of trading experience. You really have very little chance of success unless you&#x27;re doing this full time, and even then it will take years before you have enough experience to build a sustainable income.

Congratulations to the quantopian team.<p>Trading on real data is very different from simulated trading on historic data. There are a lot of leaky abstractions and assumptions that happen during simulations that cause problems once you put real money to work. In the past, here on HN, I have criticized quantopian several times because no one has actually used quantopian to trade real money. This is no longer true.<p>It will take a lot of time and a lot more capital to figure out all the holes, but they are finally on the right track and I am glad they have 20 people already trading. That is 20 sets of eyes balls to look for lack of fidelity in the simulations.<p>Personally I am interested to see how good their transaction cost model is when trading hundreds to thousands of shares at a clip.

Sweet. This is perfect for those of us who still have some money we didn&#x27;t put into MtGox left to lose!

I&#x27;d love to have a go at this but I haven&#x27;t a clue where to even start. Any tips as to where I should start reading?

Stick with value investing (or index investing if you don&#x27;t have the skill&#x2F;discipline&#x2F;time for it).

I&#x27;ve really enjoyed playing with Quantopian, and I think that I will continue to play with it as an educational tool. However my algorithms so far have been very good at losing an awful lot of money, so I think I will be sticking with simulations for now :)

This is quite interesting. I had just built a predictive rebalancing bot to trade on MtGox a few hours before it collapsed. I was rebalancing every 60 seconds and making lots of trades. I only got a couple of hours of run time before it stopped working :(<p>Here&#x27;s the bot I built: <a href="https://github.com/pontifier/rebalancer" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pontifier&#x2F;rebalancer</a><p>Quantopian looks interesting, and hopefully the exchanges it trades on won&#x27;t disappear.

It seems the natural next step would be to allow non-algorithm writers to invest in algorithms (or a bundle of algorithms), with some fee going to either or both Quantopian or the writer of the algorithm(s). Any chance that&#x27;s on the roadmap, and if so, when can I expect to be able to crowdsource my investing?

Can anyone in the know tell me why traders are not interested more in sports betting? Seems like you have a lot more people betting with heart then brain which should result in a profit if you employ all your fancy algorithms no?

I&#x27;ve always found <a href="https://www.quantconnect.com/" rel="nofollow">https:&#x2F;&#x2F;www.quantconnect.com&#x2F;</a> more interesting. They&#x27;re just not as good as Quantopian at generating some buzz.

For those interested in doing some algo testing I found this site quite interesting: <a href="http://systematicinvestor.wordpress.com/" rel="nofollow">http:&#x2F;&#x2F;systematicinvestor.wordpress.com&#x2F;</a>

The only issue that I have with that is that they require an IB account. That has a min of $10k. Thats not exactly easy to come by.

For the next week my comments on Hacker News -- except this one -- will attempt to garner as many points as possible by exploiting various HN tendencies.<p>Feel free to upvote this comment if you think this is cool btw :)
