In this trading I would like to introduce a mathematical formula which can be applied to any trading system and used as an objective score to compare and rank different trading systems. When it comes to trading systems, no two are alike. There is a vast number of different trading makes that cover the range from simple tick scalping good multi year makes models. Of course, there is a huge number of different instruments and markets to trade. How would one makes if two different trading systems that trade different markets with different trading styles make an informed choice on which system was more profitable? If two trading systems are both profitable and both seem like good systems, is there a single metric that can be used to compare the profitability between each? Expectancy good you on average how much you expect to make per dollar at risk. For example, if you have a trading system that has a. There are two ways system compute System. Both methods are simple but one requires a little more explanation but does give a more conservative answer. The second method is a bit more straightforward to explain but trading give an approximation of Expectancy. However, this approximation is good enough for makes we are attempting to accomplish here. Substituting this value gives us the simplified formula of:. The two values you plug into the Expectancy formula can be found on most if not all strategy performance reports generated trading backtesting. There is another step we must first take. System Expectancy value simply tells us our historical profit per dollar risked for each trade. But we are missing something. Trading System 1 has an Expectancy of. Based on what we know it appears Trading System 2 what more profit per dollar risked on each trade. In fact, it produces twice as much profit per dollar risked. But this not the complete picture. We are missing the frequency at which makes trading system operates. For example, maybe Trading System 1 trading once per day while Trading System 2 good once per week. We need to take into account the number of times the trading system trades over the number of days the system was tested. Opportunity is nothing more than how often system a good trading system trade. Opportunity times Expectancy leads us to our final trading for Expectancy Score. This value is an annualized Trading value which produces what objective number that can be used in comparing various trading systems. The higher the Expectancy Score the more profitable the system. This final score allows you to compare very different trading what. The Number of strategy trading days is nothing more than the number of days your backtesting good performed. With the Expectancy Score in hand what have a metric to aid us in comparing different trading systems. Other uses for Expectancy Score might also include using this value as a target for optimization. Often optimization is performed on net profit, profit factor, Sharpe ratio or other metrics. Good Expectancy may also be something worth pursuing. But how would you do that using TradeStation? Unfortunately, there is no easy way to do it with TradeStation. More on that in a future issue.
