Bankroll Charts

Last updated:

Bankroll charts plot your balance or cumulative profit over time, one point per settled bet or per day. The finance world calls the same chart an equity curve, and the reading rules carry over. Trackers draw the line two ways, as the bankroll itself or as cumulative profit from zero; the two move identically, one being the other shifted by the opening balance.

What the Line Shows

The chart is a cumulative sum: each winning bet pushes the line up by stake × (odds − 1), each losing bet pulls it down by the full stake. Over enough bets the slope of the line approximates the Yield — a steady rise at a constant angle means consistent edge, a flat or drifting line means the results are noise. The slope is the least interesting part of the chart — the shape carries the story.

Pending bets stay off the line: counting an unsettled bet as either a win or a loss inflates or deflates the chart until the result lands.

Drawdowns

The distance from a peak to the following trough is the drawdown. It is the number every bettor underweights: the line can fall 40% from its high while the overall record still ends green. Drawdowns define bankroll requirements — a strategy that needs to survive a 40% dip demands a larger bankroll than one that dips 10%, regardless of identical Return on Investment. Reading the chart’s valleys tells you what stake sizing and bankroll you can actually sustain — the same risk picture the Sharpe Ratio compresses into one number.

Recovery is asymmetric. The recovery factor equals the drawdown divided by one minus the drawdown, expressed as a fraction:

Recovery factor = drawdown / (1 − drawdown)

A line down 25% needs a 33.3% climb to return to its peak, a line down 50% needs a 100% climb. Plotting the distance from the running peak instead of the line itself produces an underwater curve that isolates the valleys from the overall drift.

Two companion numbers come off the same chart: the maximum drawdown, the deepest valley in the whole record, and the recovery time, how long the line took to climb back to the previous peak. A record that repeatedly spends months below its high is fragile even when profitable; a record that bounces back quickly can absorb deeper dips.

The odds you bet determine how deep the valleys run. According to Pinnacle’s simulations, over 1,000 even-money bets with a 4% edge a 20-unit drawdown from the starting bankroll appeared at some point in 17.4% of runs, while only 2.8% of runs finished 20 units or more in the red — a mid-record dip says nothing about where the record ends. Move the same stake and edge to odds 5.0 and the chance of touching a 20-unit drawdown rises to just under 60%. Over 1,000 bets with a 10% edge, returns vary with a standard deviation of 2.5% at odds 1.67 against 6.5% at odds 5.0, at the same +100 units expected profit. Favorite bettors see shallow dips and quick recoveries; longshot bettors see deeper, more frequent ones.

What the Shape Reveals

  • A line that climbs steadily with shallow dips describes low-variance betting at short prices
  • A line that staggers — long flat stretches, sudden spikes — describes longshot betting where results arrive in bursts
  • A staircase of short climbs and sharp drops signals staking that chases losses, the signature of Martingale-style recovery
  • A cliff — steady growth followed by a collapse — describes a system that worked until one long losing streak overran it
  • A line that climbs then falls back is either over-staking after wins or a record that was never real in the first place
  • A line too smooth for its own odds is itself suspicious: at even odds a 55% win rate still produces runs, so a perfectly straight rise implies a manufactured record

The same ending balance can hide three very different records:

  • a smooth climb
  • a wild swing
  • a slow bleed-then-recover

The chart is the only place where these three records look different. On a short record the shape proves nothing — a genuine 4% edge at even odds still ends one 100-bet run in three in the red — so give the line hundreds of bets before trusting its form.

Charts and Staking

Flat staking produces a chart that mirrors your edge directly: each result moves the line by the same stake, and the angle of the climb is the edge. Percentage-of-bankroll staking compounds the curve — a loss shrinks the next stake, a win enlarges it — so the line curves upward as the bankroll grows and the two records of identical bets look different. Comparing charts only works when the stakes were scaled the same way.

Percentage staking also slows recovery: after a losing stretch the smaller bankroll bets smaller stakes, so climbing back to the previous peak takes proportionally longer than it would with flat stakes. Plotting a compounding record in logarithmic scale keeps the angle readable as the bankroll grows, and the slope again tracks the edge. Kelly staking sits at the aggressive end of the spectrum — the higher the stake fraction, the steeper and more jagged the line.

Bankroll Charts in Tools

Few trackers surface a true bankroll curve, and they disagree on what the line shows:

  • BettingTracker draws a bankroll evolution curve on the dashboard and updates it automatically as matches settle; its Expert tier adds a Monte Carlo bankroll simulator over 1,000 trajectories and a staking plan tool that runs strategies against your real history instead of theoretical curves.
  • Bet Analytix plots capital growth curves per bankroll among its 50+ stats, so each betting fund can be charted on its own line.
  • Bet Metrics Lab Tracker runs your logged bets through staking strategies and outputs a projected bankroll curve with max drawdown for each, turning the chart from a record readout into a strategy comparison.
