How it works
Money management cannot turn a losing strategy into a winning one, but it decides how long you survive and how much a bad day costs. Risking a fixed percentage of the balance means stakes shrink after losses and grow only after gains.
Losing streaks are normal even with a decent win rate. The streak probability shows how often a day of trading will contain enough consecutive losses to hit your daily stop.
Formulas
- Stake = balance × risk per trade
- Losing trades until the daily stop = daily stop ÷ risk per trade
- Losses to halve the balance = ln(0.5) ÷ ln(1 − risk per trade)
- Expected result per day = trades × stake × (win rate × payout − (1 − win rate))
Example
With a $500 balance and 2% risk per trade, each stake is $10. A 10% daily stop-loss ($50) is reached after 5 losses in a row, and it takes 35 consecutive losses to lose half of the balance.
Rules that protect your balance
- 1Risk a small, fixed share of your balance per trade; 1–2% is a common ceiling.
- 2Set a daily stop-loss and stop trading for the day when you hit it.
- 3Never raise your stake to win back losses.
- 4Withdraw profits regularly instead of letting the balance grow at risk.
- 5Keep a journal of every trade so you know your real win rate.
Frequently asked questions
How much should I invest per binary options trade?
A common rule is no more than 1–2% of your balance per trade. With 500 in the account, that is 5 to 10 per trade.
What is a good daily stop-loss?
Many traders stop for the day after losing 5–10% of the balance. The point is to stop before frustration leads to bigger stakes.
Can money management make binary options profitable?
No. It controls risk and how long your balance lasts, but only a win rate above break-even can make the expected result positive.
