Your computer can do the trading for you without any emotional problems. A split test makes it possible to find out if something is really better than other solutions, because after a while you might get confused otherwise. Even when I did the the opposite of what I wanted to do, it also was a loss most of the time. So I started to learn automated trading. There is actually a way to gain real trading experience with thousands of trades, but in a fraction of the time you would need otherwise.
And trading errors can become very costly. But as a human, you get tired. You get a headache from time to time and sometimes you might get sick or bored. If you know how to use the two fundamental trading laws, you can greatly improve your odds for better trading results. Using several small accounts doesn’t mean that you can’t trade big accounts, but it means that my trading capital is not deposited on one broker account. Finding the right trading risk setting is the main challenge for your system. You don’t need to learn all the possible functions that our programming solution provides. In fact, it is only a tiny fraction necessary to get results. So that will save you a lot of time. Actually, there is nothing that will work all the time because no indicator is able to predict the future based on past events. I would suggest to start with forex trading.
You can always decide to try something else later at some point in time. I started to build some small and simple examples with just a few lines of code. Those examples could do only one thing, like calculating the profit or the loss for a trading account. If you improve weak things, you could probably expect mediocre results for a lot of work. But if you improve the things that already are good, you could expect excellent results with a lot less effort. Do you know how your trading system works? If not, you should probably stop trading it. I do know my own results. In real trading they are promising. But if you can expect the same results, that depends on your account type, leverage, trading costs and so on. I always encourage my course members to start with a demo account and trade that for at least three months afterwards. The next best thing would be to use a socalled cent account.
