Equity curve: 5 trades, from 10000.00.
Final Balance
$11800.00
Peak Balance
$11800.00
Max Drawdown
3.51%
How is this calculated?
Balance updates by adding each trade's net P&L to the previous balance.
Max Drawdown = largest peak-to-trough decline ÷ peak balance.

What is an equity curve?
An equity curve plots account value across a sequence of trades — a line that climbs with wins, dips with losses, and reveals the shape of the journey, not just the destination. Two strategies can end at the same final balance with wildly different paths: one steady and gentle, the other a series of deep, gut-wrenching drawdowns. The curve makes that difference visible, along with the length of losing streaks and how quickly the account recovers. It is the single most honest picture of what holding a strategy would actually feel like.
Key concepts
Equity
The running account balance after each trade.
Peak
The highest equity reached so far, used to measure drawdown.
Drawdown
The decline from a peak before a new peak is made.
A worked example with real numbers
- 1
List the sequential results
Ten trades in order: +$100, −$50, +$80, −$40, −$60, +$120, −$30, +$90, −$20, +$70.
- 2
Accumulate the balance
Starting at $1,000, the running equity becomes 1,100, 1,050, 1,130, 1,090, 1,030, 1,150, 1,120, 1,210, 1,190, 1,260.
- 3
Plot it
The line rises to a peak at trade 8 before a small dip — a smooth climb with shallow pullbacks, ending at $1,260.
- 4
Read what the shape says
The worst drawdown is $80 from 1,130 to 1,050, about 7%. The curve shows a tolerable path, not just the +26% final result.

Mistakes traders make
✗ Judging a strategy by its final balance and skipping the path
✓Two strategies can end at the same number with wildly different drawdowns. The curve tells you whether you could have held on.
✗ Ignoring long flat stretches or a single spike that carries the result
✓A curve flat for months and then one lucky run is fragile. Steady compounding is far more trustworthy.
✗ Scaling the chart to hide drawdowns
✓A zoomed-out axis makes deep dips look trivial. Read the axis and the actual percentage before trusting the shape.
When this tool fits — and when it does not
Use it when
- ✓After every batch of closed trades, to see the path of your account.
- ✓When comparing strategies with the same return but different risk paths.
- ✓Before committing more capital, to confirm the drawdowns are survivable for you.
Skip it when
- ✗Reading a curve after five trades — it is still mostly noise.
- ✗Extrapolating a steep early climb as the future pace.
- ✗Using the curve alone without the trade-by-trade data behind it.
Practical tips that actually help
Plot the equity, not just the P&L bars
The running total exposes streaks and recovery lengths that a list of individual results hides.
Mark your own rule changes on the curve
Know where you modified the strategy. A bend that follows a change is a clue about cause and effect.
Watch the drawdown-to-gain ratio
A healthy curve climbs with shallow dips; one that needs a 40% drawdown to gain 20% is a warning regardless of the final number.

Frequently asked questions
Why look at the curve instead of the final balance?▾
Two strategies can end at the same balance with very different paths — one smooth, one with deep drawdowns. The path determines whether you could actually hold on.
What does a healthy equity curve look like?▾
There is no single ideal shape, but the signs of a robust curve are controlled drawdowns, recovery after losses, and growth that is roughly steady rather than driven by one or two lucky trades.
What should I watch for on an equity curve?▾
Look for long flat stretches or deep troughs, a curve that only rises because of a single outlier trade, and drawdowns that keep getting bigger — these often signal fragility that a headline return hides.
How is an equity curve different from a price chart?▾
A price chart shows an asset's market price over time. An equity curve shows your account balance after each trade, so it reflects your strategy's decisions and results, not the underlying market.
Can I build an equity curve from a backtest?▾
Yes, and you should. Plot the backtest's cumulative P&L, not just the final total, so you can see the drawdowns and losing streaks you would have had to live through to reach that result.
