If you only learn one thing about trading, make it this: risk management is the difference between traders who last years and traders who blow up in their first month. You can survive a mediocre strategy with great risk management. You cannot survive a great strategy with terrible risk management.
Your #1 job: don’t lose money
This sounds backwards, but your primary job as a trader isn’t to make money — it’s to not lose it. Profits come as a byproduct of surviving long enough for your edge to play out. Protect your capital first; the gains follow.
The 1-2% rule
Never risk more than 1-2% of your total account on a single trade. If your account is $1,000, your maximum loss on any one trade is $10-$20.
This feels overly cautious until you see the math. Here’s why it matters:
- At 2% risk per trade, you’d need to lose 35 trades in a row to be down 50%.
- At 10% risk per trade, you’d only need to lose 7 in a row for the same damage.
Losing streaks happen to everyone. The 1-2% rule is what lets you survive them without emotional or financial ruin.
Position sizing: the formula
Your position size comes from three inputs: account balance, risk percentage, and the distance from entry to stop loss:
Position Size = (Account × Risk%) ÷ (Entry − Stop Loss distance)
Example: a $10,000 account risking 1% ($100), with a stop 2% away from entry → position size of $100 ÷ 0.02 = $5,000 of notional exposure. We go deeper in our dedicated position sizing guide.
Risk-reward: let the math work for you
Never take a trade where the reward is smaller than your risk. Aim for at least 1:2 — risking $10 to make $20. At a 1:2 ratio you can be wrong on half your trades and still profit. At 1:3, you can be wrong 60% of the time and still come out ahead. Let the math carry you.
Drawdown limits
Set hard rules for when to stop and reassess:
- Pause after losing 5% in a single day.
- Pause after 10% in a week.
- Pause after 15-20% in a month.
These forced breaks prevent emotional decisions when you’re most likely to make them.
A few hard rules
- Use isolated margin, not cross, until you fully understand the difference.
- Place stops beyond key technical levels, not at arbitrary tight distances that get hunted.
- Cap yourself at 2-3 high-quality trades per day. Discipline beats activity.
