Quote from JB3:
If there is profit to be made, of course I would lease it. But that all depends on what type of strategy is used, the liquidity it can handle, and of course profitability. The client would probably want to see some records to make sure everything works. Backtest is usually not preferred because any joker can produce profitability on fitted data, and I would also be weary of how the system handles the mechanics of trading...if there is fast data or sudden spikes, how does the system handle it...and what failsafes are put into place. Like the Knight Capital fiasco, the last thing we need is to have execution errors or order problems (loops)...and sudden drain the whole account because of some code bugs.
I would not be interested in any third party sites like C2. Why would I give another middle man some cut of the profit that provide no services that is necessary to make money?
