I have been thinking a lot about the fact that the absolute fastest, most powerful computer on the planet for trading is the human mind. The only problem with it, is that it is infected with the "emotion" virus that makes it not quite as good as it should be for trading. You could try and build a system and let a normal computer trade it, but it's all but impossible to really build a self adapting, logically thinking system on a PC. So how can we use the most powerful computer and bypass or eliminate the emotion virus? Two thoughts come to mind. The first one would be to find a true sociopath (person completely devoid of emotion) and teach them to trade your account. The problem with this is that they are very rare and usually end up as serial killers. The second thought is the main one I have been thinking about. If you have 2 traders with a similar system of manual trading and both are profitable but not great due to emotional mistakes...would they trade better if they traded each other's accounts instead of their own? By trading someone else's account it could reduce your emotional stress b/c it's not your money and thereby allow better smarter trades. The issue I see with this is if one trader makes his buddy 50% in a month and his buddy only makes 10% there could be some friction. Either way it is an interesting hypothesis I think.
