As I explained in other threads, I am not a computer science nor a math major, so I don't have enough of a background to make use of complicated money management formulas. I can only understand things like "invest x% on this system and y% on this other system", but I cannot grasp sharpe ratios, profit ratios... I get lost in all those ratios given by tradestation reports. If anyone has simple ideas for money management - something like "money management for dummies" - please let me know. It would be appreciated and it would help me reason about this new concept that I am starting to understand only after incurring financial ruin repeatedly. I have built about 20 different systems (in some cases, it's the same system, but traded on a different security) on excel, coding them in VBA, which is a great accomplishment for me, and they all work. However, these systems don't have a very high win ratio - they only win about 60% of the time, and they do win a bit more than they lose. As you can see, I am talking in simple terms and not giving out exact formulas, because I can't handle them. What happened to me with these systems is that in the past year, twice, I doubled my money (trading the systems on futures, which makes it much easier) each month for about 3 months, bringing it from a few thousands to about 25k. Then suddenly, in less than one month, I lost it all. Now that I am starting for the third time, which money management advice am I giving myself? I've been thinking really hard, not just based on the tradestation tests but even more on what I saw in practice, which systems work best, and accordingly which systems I should trade more. Once again, I'd rather do this without using any complicated formulas, but only a simple ratio (with percentages) of how much to invest on each system. With the little capital I had, both times I started with the systems that required the least margin. I got lucky, but they were too correlated. Now I am starting with just the one future that has the least drawdown (no formula to gather the drawdown, but an overall estimate I am making). If I ever get up again to a capital of 20 thousand dollars, I am planning to increase the investment to 4 contracts for this future that seems to have the best performance. At the same time, I will also trade the other futures, to provide some diversification. So far my money management consists of the attached excel sheet. I know I sound very illiterate, but if anyone feels like it, let me know any simple advice on money management. Beware, even the Kelly criterion is too complicated for me. I tried it, I understand it, but it is complicated because it involves the use of other formulas (the probability of success of my systems, which I don't even know for sure)... basically it all gets too complicated and makes too many assumptions. I know I sound ignorant or even stupid but I'd like to hear simple sentences like "invest more on the system that has the highest percentage of wins", or "invest ONLY on the system that has the highest percentage of wins", or "invest equally on all systems", or "invest ALL on the system that gives you the highest return". One thing I did understand is that it is not sure that the system that makes more money or even the system that has the highest percentage of wins, is the system that I should start with or invest the most in. I also realize that a major concept is the concept of maximum drawdown (whether it is an exact number from a formula, or a rough estimate I am making).
