An equity curve is the graph showing how much your trading or investment account increases or decreases over time.
Monitor Performance: It can help you monitor performance as its curve goes up or falls down. A smooth upward curve means consistent profits. A jagged or downward curve highlights volatility or losses, showing where things might be going wrong.
Manages Risk: By spotting big dips (called drawdowns), you can see when your account took a hit. This can help you tweak your strategy, like adding stop-losses or reducing trade sizes.
Guides Decisions: Other traders base their decisions to raise or decrease their trade sizes by taking cues from equity curves. If the curve shifts up, it might mean increasing one's exposure; otherwise, the curve is dipping down below the average line and hence a time to draw in.
An equity curve serves as a performance report for any trading or investment strategy and helps you understand what's working, identify risks, and make better decisions to keep your account growing steadily.
