Money Management
NAV evolution with different money management formulas applied.
The results are based on the last 106 trades generated by my system..
I got the idea to test different money management rules from some discussions I've read through most of the FX forums around; and it's all about knowing when to increase the risk per trade, lot sizes etc;
One of the things that made me choose Oanda as my broker is that it allows a flexible position sizing, you can trade any number of units from 1 unit to 25 mil. Taking advantage of that I've tested various formulas and this is what I've come up with.
The darker line is the evolution of NAV, when the next trades size is determined by adding/subtracting half of the "%" increase in NAV of the last trade. I followed -~chaffcombe's model but scale it down to a trade by trade, rather than day by day.
The pink line on the chart is a "classical" MM model, that increases the lot sizes when the account grows, according with my systems stop/loss requirements I started with risking 0.5% per/trade and increasing the risk by another 0.5% when the account has gotten to a predetermined level.... (on second thought this is not exactly classical).
The yellow line is the results of increasing the percentage risked per trade by half of the previous trades gain/loss as % NAV, also this started by risking 0.5% on the first trade;
For example if the last trade made 1.5% NAV in profit's, the next trades risk will be 0.5%+ 0.5*1.5%= 1.25% ...it is a rather aggressive model, and still under tests.
Risking the same fixed percentage on every trade proved to be the method that helped the less with compounding so i did not put it on the chart, nor considered to use it myself.
