A graphical representation of the change in value of a trading account over a time period. An equity curve with a consistently positive slope would generally indicate that the trading strategies of the account are profitable, while a negative slope would indicate that the account is in the red.
Since it presents performance data in graphical form, an equity curve is ideal for providing a quick analysis of how a strategy has performed. Also, multiple equity curves can be used to assess various trading strategies in terms of performance and risk.
