However, many market traders believe that theyre doing a sufficient job of position sizing by simply having a stop loss in effect. While this can tell them when to get out of a stock exchange position, and will, with a maximum loss, figure out how much capital theyre risking, it doesn't answer the problem of how much or how many units they can buy. While it is easy, the formula Im about to offer you is very strong.
A stop loss size is the difference between your entry price and your stoploss worth. If your market entry price was one dollar, and your stop-loss price was ninety cents , your stop size would be 10 cents . Now, the quantity of shares is the same as your maximum loss divided by your stop size. As you know, the number of shares you can buy is set by your maximum loss and the dimensions of your stop. By simply shrinking your stop size, that is by setting a tighter stop loss, you can increase the dollar price of the position you open. This rule would constrain the greenback value of a position to be less than a set proportion of your complete currency trading float.
The p.c. that you decide on will rely upon the sort of system you are trading, the dimensions of your float, and your private toleration for risk. Test your system to discover which of the variables best suit you, recollecting always that position sizing is the most serious part of any system design. Once youve tested your system, and enhanced your rules, you'll be well on the way to changing into a successful Forex trader .
