Most traders spend hours on entries and seconds on the question that decides whether they survive: how much of the account goes at risk on each trade? This guide answers it with plain math, not rules of thumb.
The short answer
For most retail traders, 0.5% to 1% of the account per trade is the range where normal losing streaks stay survivable. 2% is the upper limit for experienced traders with a tested strategy. 5% or more per trade turns an ordinary bad month into an account-ending one.
The reason is losing streaks, and they are longer than most people expect.
Losing streaks are normal, even for good strategies
We analyzed 20,000 simulations of 239 trades, matching the parameters of our 12-year swing test, based on the observed 50% performance rate of our swing engine during testing. Trading carries a high risk of loss; past results do not guarantee future results.
- The typical longest losing streak was 7 trades in a row.
- In 1 run out of 10, the longest streak reached 10 in a row.
- In about 37% of runs there was at least one streak of 8 or more.
At a 40% performance rate, which is common for trend strategies targeting larger winners, the typical longest streak of losses was 9, with 1 in 10 runs reaching 13. Trading carries a high risk of loss; past results do not guarantee future results.
So a streak of 8 to 10 losses is not bad luck. It is something you should plan for.
What a losing streak does to your account
Here is the drop from 8 and 10 losses in a row, with risk taken as a percentage of the current balance:
| Risk per trade | 8 losses in a row | 10 losses in a row |
|---|---|---|
| 0.5% | -3.9% | -4.9% |
| 1% | -7.7% | -9.6% |
| 2% | -14.9% | -18.3% |
| 3% | -21.6% | -26.3% |
| 5% | -33.7% | -40.1% |
At 1%, ten straight losses cost under 10%. At 5%, the same streak removes 40% of the account, and you then need a 67% gain just to get back to where you started.
The recovery problem
Losses and gains are not symmetrical:
- Lose 10%, you need +11% to recover.
- Lose 20%, you need +25%.
- Lose 40%, you need +67%.
- Lose 50%, you need +100%.
Small risk keeps you in the zone where recovery is realistic.
How to choose your own number
- Know your strategy's worst drawdown in R. R is one unit of risk. Our swing engine's worst drawdown in its 12-year test was -8.1R. At 1% risk that is roughly an 8% drop; at 2% it is about 16%.
- Decide the drop you can live with without changing your plan. Be honest. Many traders abandon a good strategy at -15%.
- Divide. Acceptable drop ÷ worst drawdown in R, then halve it for safety, because the future can be worse than the test. Example: 15% ÷ 8.1R ≈ 1.85%; halved ≈ 0.9% per trade.
- Cap total open risk. Several open trades in correlated pairs (EUR/USD and GBP/USD, for example) act like one bigger trade. We cap total open risk at 3% across all VIP swing signals.
Turning a percentage into a lot size
Position size = (account × risk %) ÷ (stop distance in pips × pip value per lot).
Example: $5,000 account, 1% risk = $50. Stop of 40 pips on EUR/USD, where one standard lot is worth about $10 a pip: $50 ÷ (40 × $10) = 0.125 lots, so about 0.12 lots.

Frequently asked questions
Is the 2% rule safe?
It is the upper end. With a 50% performance rate, a sequence of 10 losses at 2% risk results in a drawdown of approximately 18%. Trading carries a high risk of loss; past results do not guarantee future results. Beginners are usually better served by 0.5% to 1%.
Should I risk more after a winning streak?
Not as a rule. Keep risk as a fixed percentage of your current balance. Your position size then grows with the account on its own, and shrinks during drawdowns.
Does a higher win rate let me risk more?
A bit, but streaks still happen. Even at 60% winners, streaks of 6 or more are common over a few hundred trades.
What risk do TebotechSignals VIP swing signals suggest?
Each VIP swing signal carries a suggested risk between 0.25% and 1.5%, set by our risk optimizer so total open risk stays at or under 3%.
