This ProBuilder code snippet is designed to calculate and plot the average gain per unit stake over time for a trading strategy. This metric helps in evaluating the performance consistency of a strategy, irrespective of the stake size used. It’s particularly useful for comparing different strategies or the same strategy across different instruments.

if countofposition > countofposition[1] then
    trades = trades + (countofposition - countofposition[1])
endif

if strategyprofit <> strategyprofit[1] then
    averagegain = strategyprofit/trades
endif

graph averagegain

Explanation of the Code:

• Tracking Trade Count: The code starts by checking if the current number of positions (countofposition) is greater than the number of positions in the previous period (countofposition[1]). If true, it calculates the difference and updates the trades variable. This part is crucial for keeping track of how many new trades were executed.
• Calculating Average Gain: Next, the code checks if the strategy’s profit (strategyprofit) has changed from the previous period. If there is a change, it calculates the average gain by dividing the total strategy profit by the number of trades. This gives the average gain per trade, normalized to the unit stake.
• Plotting the Result: Finally, the average gain is plotted using the graph function. This visual representation helps in analyzing the performance trend of the strategy over time.

This snippet is a straightforward yet powerful tool for assessing the effectiveness of trading strategies, making it easier to identify stable and potentially profitable approaches.
