Bankroll management is the big picture of handling your trading money: how much capital to dedicate to trading, how to protect it, how to grow it and when to take money out. Position sizing decides how much to risk on one trade. Bankroll management decides how much money is in the game at all, and how it changes over months and years. The term comes from gambling, but the principles are the same for traders and prediction market participants.

## Step 1: Separate your trading capital

Your trading bankroll should be money you can afford to lose without affecting your rent, bills, emergency savings or retirement. Keep it in a separate account so it is always clear how your trading is doing. Never top it up with money meant for something else after a loss.

| Money | Purpose | Belongs in trading? |
|---|---|---|
| Emergency fund | Several months of expenses | No |
| Retirement savings | Long term investing | No |
| Short term needs | Rent, bills, planned purchases | No |
| Discretionary risk capital | Money you could lose entirely | Yes |

## Step 2: Fund in stages

Start with a portion of your intended capital. Add more only after you have proven, over a meaningful number of trades, that you can follow your plan and produce results in line with expectations. This limits the cost of the learning phase. See [Moving From Paper to Live Trading](https://learn.tradelabsai.com/start-here/paper-to-live-trading/).

## Step 3: Protect the bankroll

- **Risk a small fixed percentage per trade.** See [Position Sizing](https://learn.tradelabsai.com/risk/position-sizing/) and [Fixed Percentage vs Fixed Dollar Risk](https://learn.tradelabsai.com/risk/fixed-percentage-risk/).
- **Set daily, weekly and drawdown limits.** See [Maximum Trade Risk and Daily Loss Limits](https://learn.tradelabsai.com/risk/daily-loss-limit/).
- **Reduce size in drawdowns.** For example, cut risk per trade by half after a 10% drawdown until it is recovered.
- **Stop and review** after a predefined maximum drawdown, such as 20%.

## Step 4: Growing the bankroll

Fixed percentage risk compounds automatically: as the account grows, each position grows. Compounding is powerful over time but depends on keeping drawdowns small. See [Compounding and Geometric vs Arithmetic Returns](https://learn.tradelabsai.com/math/compounding/).

**Example: Compounding a modest edge**
A trader averages +0.25R per trade, risks 1% per trade and makes 200 trades a year. That is roughly +50R, or around 50% of the starting balance in simple terms, though actual compounded results will differ because of the order of wins and losses and costs. Raising risk to 3% would not triple results safely; it would sharply increase the chance of a deep drawdown. See [Risk of Ruin](https://learn.tradelabsai.com/risk/risk-of-ruin/).

## Step 5: Withdrawals

Taking money out is part of bankroll management, especially for traders who rely on trading income. Common approaches:

| Approach | How it works |
|---|---|
| Fixed percentage of profits | Withdraw, say, 30% to 50% of each month's profit |
| High water mark withdrawals | Only withdraw from profits above the previous peak balance |
| Target balance | Withdraw anything above a chosen working balance |
| Scheduled salary | Withdraw a fixed amount monthly, accepting slower growth |

Withdrawing after drawdowns, when the account is below its peak, can lock in losses and reduce your ability to recover. High water mark rules avoid that.

## Bankroll management in prediction markets

For prediction markets, bankroll management means sizing each position as a small fraction of your total betting capital, even when you feel very confident, because a share can go to zero. Kelly based sizing is common in betting circles, but with fractions well below full Kelly because probability estimates are uncertain. See [Kelly Criterion](https://learn.tradelabsai.com/risk/kelly-criterion/) and [Prediction Market Strategies and Risks](https://learn.tradelabsai.com/prediction-markets/prediction-market-strategies/).

## Common mistakes

- **Trading with money you need.**
- **Adding funds after every loss** to "get back to even".
- **Withdrawing everything after a good month,** leaving no buffer.
- **Increasing risk percentage as the account grows,** on top of compounding.

## Frequently asked questions

### What is bankroll management in trading?

The overall management of your trading capital: how much to commit, how to protect it, how to grow it and when to withdraw profits.

### How much money should I use for trading?

Only money you could lose entirely without affecting your essential expenses, savings or retirement.

### When should I withdraw trading profits?

Many traders withdraw a share of profits regularly, often only from gains above their previous peak balance, so that drawdowns are not locked in.
