Trading Software for Position Sizing


Market System Analyzer (MSA) is a software application for traders that simulates trading with position sizing. The software is designed to increase returns while limiting risk in existing trading systems and methods. MSA can be used to evaluate trading systems or methods, explore different position sizing options, optimize trade sizes, and perform position sizing calculations on a trade by trade basis.

Position sizing is a money management method for determining the number of shares or contracts to trade. It's an effective risk management strategy that can be used to increase returns, reduce or control risk, improve the risk/return ratio, and smooth the equity curve, among other goals. Market System Analyzer (MSA) is designed to make it easy to apply any one of 15 position sizing methods. In addition, the optimization feature of MSA combined with its Monte Carlo analyzer can help find the position sizing settings that meet specific trading objectives.


In MSA, the position sizing method is chosen from the Position Sizing command of the Analysis menu:

The number of shares or contracts for an upcoming trade can be calculated by entering the current value of account equity and, if applicable, the trade risk, entry price, and average true range (ATR). The number of shares/contracts will be determined from the position sizing method and options currently in effect.
