How Much Should You Risk Per Trade?
Here's the thing nobody tells beginners: most trading accounts don't die from bad predictions. They die from bad sizing. You can be right more often than wrong and still go broke if your losers are huge and your winners are small. The one lever you fully control isn't the market — it's how much you put at risk on each trade.
The short answer: 1–2%, and beginners should start at 1%
Professional risk management usually means risking a fixed 1–2% of your account per trade. When I started journaling my own trades, I set mine at 1% — and that single decision did more for my account than any indicator ever has.
Why a percentage instead of a fixed amount? Because a percentage automatically shrinks your risk when you're losing (protecting you in drawdowns) and grows it as you win (compounding). It's a built-in safety system that requires zero willpower.
Turning risk % into a position size
Your risk budget and your stop-loss together decide how big the trade should be:
Example: a $5,000 account risking 1% has a $50 budget. Entry at $20.00 with a stop at $19.00 means $1.00 of risk per share — so the position is 50 shares. If the stop gets hit, you lose exactly $50. No surprises, no blown account.
You can do this by hand, or use the free position-size calculator I built — it does stocks, crypto and forex.
The drawdown table that changed my mind
Losses are asymmetric — a loss needs a bigger gain to recover:
| If you lose… | You need this to get back to even |
|---|---|
| 10% | +11% |
| 20% | +25% |
| 50% | +100% |
| 70% | +233% |
Lose half your account and you have to double what's left just to break even. This is the entire argument for small, fixed risk: it keeps you out of the hole that's nearly impossible to climb out of.
What I actually do
- Risk is fixed at 1% — decided before the trade, never during.
- Position size always comes from the formula, never from a feeling.
- Every trade gets logged with its result in R (profit ÷ initial risk), so wins and losses are comparable.
- No trade below 1:1 reward-to-risk — at 1:2, a 33% win rate breaks even; at 1:3, just 25%.
I built my whole journaling system around this — the free calculators are here, and the full workbook version is coming to the shop soon.
