ROI ...What are the tactics to make ROI as done by mrh +76,233%?

Hi, I am curious to know, if any of you are prepared to answer, as to what sort of trading tactics may generate amazing ROI such as done by mrh +76,233% on ipredict. I hope you can give me an insight. Cheers!

Several traders have observed someone exploiting bugs in the market maker to make hundreds of dollars for no risk. On a couple of occasions where this happened, mrh's subsequently ROI increased dramatically.

When I joined, mrh had a ROI of something around 30-40,000%. I suspect mrh started with a very low deposit, something like $20-50, and made a couple of very lucky (or very insidery) trades, and has just been trading the profits since then. With such a low starting deposit, it doesn't take much of a profit to make a big increase in the ROI.

Thanks for your response Lanthanide. Much appreciated. Cheers!

A $20 deposit would still mean a return of over $15K, which is super-impressive whichever way you slice it. It takes more than dumb luck for that.

Bugs?

Like when a stock hasn't closed after the event but an marker is still repeatedly available?

If you're talking about the bog-standard arbitrage on the bundles, I don't think mrh had any part in that.

OK, so hero to many MRH loses over $300 yesterday but her/his ROI stays at 77,019%!

Is this ROI run by the same calculator that mismanages the 'avg. cost'?

{is there some connection to Treasury prediction calculators???}

He would've made a withdrawal-withdrawals don't affect ROI%, only deposits.
