Equity Curve
Also known as: equity chart, account curve
What is it?
An equity curve is a chart that plots the value of a trading account over time. Instead of giving you just a single final profit number, it shows the whole journey, every rise from winning trades and every dip from losing ones, so you can see the path the account actually took. Reading the curve from left to right tells the story of the strategy: long smooth climbs, sharp spikes, sudden drops, and the drawdowns where the account fell below a previous high. The shape of an equity curve often reveals more about a strategy than its headline return does.
Two strategies can both finish a year up 30%, but one might rise in a steady, gentle slope while the other doubles and then nearly halves before recovering. The end number is identical, yet the second would be far harder, and far more stressful, to actually hold through. A smooth, consistent curve with shallow dips is generally easier to trade than a jagged one with violent swings, because you are less likely to abandon it in fear at the worst moment. What an equity curve cannot do is predict the future.
It is a record of what has already happened, whether from live trading or a backtest, and a strong-looking past curve does not guarantee a similar future one. Markets change, past performance does not guarantee future results, there is no risk-free strategy, and your capital remains at risk.
Why it matters: The shape of the curve - smooth versus jagged, steady versus spiky - tells you far more about a strategy's character than its headline return.
The equity curve reveals the lived experience of a strategy that a single return figure hides.
Real-world example
Two strategies end the year up 30%, but one curve rises steadily while the other doubles then halves - very different to trade.
How SignalBots handles it
SignalBots plots equity curves on performance pages so a feed's path - not just its total - is visible, with a /risk-warning link.
Pro tip
Favour smoother, more consistent equity curves over spiky ones with the same return; they are far easier to hold through.
Common pitfalls
Judging a strategy by its end point and ignoring a violent curve you could never have stayed invested in.
Frequently asked questions
What makes a good equity curve?
Consistency. A steady upward slope with shallow drawdowns is easier to trade than a spiky curve with the same end return. Past curves are historical and do not guarantee future ones.
Why not just look at the final return?
Because the final number hides the journey. A violent curve that swung deeply down before recovering can be impossible to hold through in real life, even if it ended at the same profit as a calmer one.
Does a smooth past curve mean smooth future trading?
No. The curve records what already happened. Market conditions can change, producing a rougher future path. A smooth history is reassuring context, not a forecast, and your capital is at risk.
What do the dips in an equity curve represent?
They are drawdowns, periods where the account fell below an earlier high before recovering. Their depth and how long they lasted show how much pain the strategy historically demanded from a trader.
Is a backtested equity curve as reliable as a live one?
Usually less so. A backtested curve depends on assumptions about costs and fills that may not hold live. A live or forward-tested curve reflects real conditions, though neither guarantees future results.
Trading involves substantial risk of loss. Historical and backtested results do not guarantee future performance. Read the full risk warning.
