Definition 
The total profit or loss generated from your long trades over a specified period.

Formula
Return $ on Long = Sum of (Profit or Loss on Long Trades)

Example
Imagine you have the following trade history for a week, with the side indicated:

• Trade 1: Profit of $100 (Long)
• Trade 2: Loss of $50 (Short)
• Trade 3: Profit of $80 (Long)
• Trade 4: Profit of $30 (Short)
• Trade 5: Loss of $75 (Long)

Your Return $ on Long would be: $100 + $80 – $75 = $105

• Strategy Refinement: Can indicate if adjustments are needed to your long trading strategies.

Considerations

• Overall Context: It’s important to compare this to your “Return $ on Short” to get a complete picture of performance by trade direction.
