The 1% Rule: How to Manage Risk in Swing Trades
The 1% rule is a key risk management strategy for swing traders, where a trader aims to limit each loss to 1% of their portfolio's value. This simple, but nevertheless...
Risk management is the part of swing trading that decides whether you are still trading next year. It is also the part that gets the least attention, because it is arithmetic rather than a pattern.
The framework is short: decide the most you will lose on a trade, place the stop where the idea is actually wrong, and let the distance between entry and stop determine the size. Everything else is discipline.
Fix the risk before the size
The order matters. Most people decide how much to buy and then look for a stop that fits their comfort. The professional order is the reverse: the stop is set by the structure of the chart, and the size is whatever makes that stop equal a predetermined fraction of the account.
The fraction is the 1% rule in its common form - risk one percent of the account per trade - and the reason it is a percentage rather than a dollar figure is that it scales as the account changes. Our archive covers it in The 1% Rule.
Position size is a division
Once risk per trade and stop distance are fixed, size is not a judgement call. It is the risk divided by the distance from entry to stop, expressed in whatever unit you are trading. Nothing about the setup changes the arithmetic.
This is what makes a wide-stop trade automatically smaller and a tight-stop trade larger, which is the correct behaviour and the opposite of what feels natural. Our archive covers the mechanics in Managing Risk Through Stops and Position Sizing and Position Sizing Based on Volatility.
Stops go where the idea is wrong
A stop placed at a round number because it is a round number, or at the maximum loss you can tolerate, is not a stop - it is a hope with a number attached. The stop belongs at the level that would tell you the premise of the trade has failed: below the swing low you bought against, back inside the range you thought had broken.
That level is set by the market, not by you, and the size then has to accommodate it. If the resulting position is too small to be worth trading, the trade is too wide for the account, and the answer is to skip it rather than to move the stop.
Think in R, not in dollars
The useful unit for reviewing a strategy is the multiple of the risk taken, usually called R. A trade that risks one percent and makes two is +2R regardless of account size, which makes results comparable across periods and across instruments.
This reframes the question from win rate to expectancy. A strategy that wins a third of the time at 3R is profitable; one that wins two thirds of the time at 0.5R is not. Win rate on its own says almost nothing.
Drawdown is the real constraint
Losses compound against you asymmetrically. A drawdown of ten percent needs about eleven percent to recover; a drawdown of fifty percent needs a hundred. That asymmetry, not any single trade, is what ends accounts.
It also sets a practical limit on how many positions you hold at once. Ten positions each risking one percent is a ten percent loss if the market moves against all of them together, which correlated positions do. Position count is a risk decision, not a diversification decision.

Questions
How much should I risk per swing trade?
The common framework is one percent of the account. The figure matters less than applying the same one consistently and sizing from it.
How do I calculate position size?
Risk per trade divided by the distance from entry to stop. Fix the stop from the chart first, then let that distance determine the size.
Where should I put my stop loss?
Where the premise of the trade is proven wrong - below the level the setup depends on - not at the maximum loss you find tolerable.
How many positions should I hold at once?
Few enough that the combined risk if they all move against you together is survivable. Correlated positions behave like one larger position.
What is a good win rate?
It is not meaningful on its own. What matters is expectancy: average win size times win rate against average loss size times loss rate.
