Risk Management in Trading: Position Sizing and the 1% Rule

Updated 10 min read Fix Pips

In short

Risk management in trading is the set of rules that cap your loss before you enter: risk per trade (usually 0.5–1% of the account), a stop loss beyond the point where the idea stops working, and a position size calculated from the stop distance. Formula: size = risk amount ÷ (stop in points × point value per lot).

Risk management: sizing a position from the stop Long: entry, a stop 25 points below and a take profit 50 points above. On the right, the math: €100 risk on a €10,000 account at 1%, size = €100 ÷ (25 × €1) = 4 lots of GER40. Risk = distance from entry to stop × position size take profit entry stop risk: 25 pts = 1R target: 50 pts = 2R GER40 position size 1. Risk in money: €10,000 × 1% = €100 2. Stop in points: 25 pts 3.

Risk management: sizing a position from the stop

What is risk management in simple terms?

Risk management is the answer to "how much will I lose if I'm wrong?", asked before you enter. Chart analysis decides where to get in. Risk management decides whether your account survives the mistakes that analysis will make.

It comes down to three decisions:

  1. Risk per trade — what percentage of the account you are willing to lose on a single trade.
  2. Stop loss — the level at which the idea is considered wrong.
  3. Position size — how many lots to trade so that the stop costs exactly the planned amount.

The order matters. The chart sets the stop, your rules set the risk, and math sets the size. Never the other way around.

How much should you risk per trade?

Our guideline is 0.5–1% of the account per trade and no more than 1% in total per day. Why so little? Because losing streaks are inevitable. At 1% risk, five stops in a row is −5%: unpleasant, but recoverable. At 5% risk, the same streak eats almost a quarter of the account, and you need to make about 30% just to get back to where you started.

In one of our posts (in Russian) we explained why "5% a day" isn't a strategy: hitting it forces you into trades with oversized risk, and one bad week wipes out a month of work. Realistic guidelines are daily risk of up to 1%, measuring success in percent rather than dollars, and treating a profit as a signal to stop, not to double your size.

You can and should vary risk within that range. A trade that meets every rule with a safe stop gets full risk. An aggressive entry, a countertrend trade or a news day gets half or a third.

Where should you put your stop loss?

The stop goes where your idea stops being right. Not at a "round 20 points", and not at an amount you don't mind losing. We use three options:

Stop placement Where Pros Cons
Beyond HTF invalidation Beyond the 4h or 1h zone the idea comes from Most reliable; rarely taken out by noise Wide stop means smaller size and lower R
Beyond the sweep extreme Beyond the high or low that swept liquidity before the entry A balance of reliability and size Risk of a resweep, a second run on the same level
Beyond LTF invalidation Beyond the 3m–5m structure Tight stop, high R High chance of getting stopped out; only with reduced size

The rule we follow: the less protected the stop, the smaller the risk per trade. You can see it in our reports in lines like "took 0.5 risk because the stop isn't fully safe". One more thing: don't place the stop exactly beyond an obvious high or low. That is where liquidity sits, and the market loves to sweep it. Add a buffer for the spread.

How do you calculate position size?

The formula in words:

  1. Risk amount = account balance × risk percentage.
  2. Stop cost per lot = stop distance in points × point value for 1 lot.
  3. Position size = risk amount ÷ stop cost per lot, rounded down to the lot step.

Point value depends on the instrument and the broker. For GER40, many CFD brokers and prop firms set 1 lot = €1 per point, but you will also see contracts at €5, €10 and €25 per point. Always check the instrument specification. If your account is in dollars, convert the point value at the current EUR/USD rate.

Position size example for GER40

Say you go long from a test of a 1h BISI, with the stop beyond the low that tested the zone, 25 points away. Account €10,000, risk 1%:

  • risk amount: €10,000 × 1% = €100;
  • stop cost per lot: 25 pts × €1 = €25;
  • position size: €100 ÷ €25 = 4 lots.

If price hits the stop, you lose €100 plus spread and commission. If it reaches the take profit 50 points away, you make €200, or 2R.

Account Risk Risk amount Stop Size at €1 per point
€10,000 1% €100 25 pts 4 lots
€10,000 0.5% €50 25 pts 2 lots
€10,000 1% €100 40 pts 2.5 lots
€25,000 1% €250 18 pts 13.8 lots (13.89 → round down)
€100,000 (prop) 0.5% €500 30 pts 16.6 lots (16.67 → round down)

Look at the third row: a wider stop means a smaller size, while the risk in money stays the same. That is exactly how it should work.

The same calculation on DAX futures shows why CFDs or micro contracts are easier for beginners. A standard FDAX is €25 per point, a Mini-DAX (FDXM) is €5, and a Micro-DAX (FDXS) is €1. For €100 of risk and a 25-point stop you would need 0.8 FDXM contracts, which isn't possible, but 4 FDXS contracts fit the risk exactly.

Position size calculator

So you don't have to do the math by hand before every trade, we are building a risk calculator for GER40, NAS100 and JP225: enter your account size, risk percentage and stop in points, and get the position size. Until it launches, keep the formula above in your notes and run the numbers before you click the button.

What is R and why measure trades in R?

R is the size of your risk on a trade. A stop is −1R; a take profit two stops away is +2R. Measuring in R removes account size from your stats and lets you compare trades with each other: +2R on a €5,000 account and +2R on a €100,000 account are equally good trades.

Your risk-to-reward ratio determines what percentage of winning trades you need to avoid losing money:

Target Breakeven win rate (before commissions)
1R 50%
1.5R 40%
2R 33%
3R 25%

A high R isn't a goal in itself. The farther the target, the less often it gets hit. We more often take partial profits at the first liquidity and move the rest to breakeven.

How we manage risk at Fix Pips

Our working rules:

  • risk per trade from 0.3% to 1%, depending on how good the stop is and the context;
  • a position can be built in parts, and the total risk never exceeds the plan;
  • after the first target the position is partly closed or moved to breakeven;
  • against a higher-timeframe zone — reduced risk only, or no trade;
  • stops are published just like winners, including trades that broke the rules.

After price held below the Asian session low, a new 15-minute structure formed. The first position was 1% from the 0.5 level, the second 0.5% from a test of the zone and a deeper OTE retracement. The risk was split in advance: the aggressive entry got the smaller size.

The most expensive mistakes aren't in calculating size but in managing the trade. Here is one worth remembering:

Two positions after a test of a 4h SIBI and an SMT on the 30-minute fractal. The first was closed in profit on the hourly fractal, about 2R. The second was held for a test of a weekly inefficiency worth 2.3R and got stopped out. The author's review: idealizing the position; take profit at the first zones.

Trade in the journal (RU)

The difference between taking profit and getting stopped out: 0.3R of extra profit versus a full R of loss. Decisions like that only show up in a trading journal: record not only the result of a trade, but also where you could have closed it by your rules.

How do you scale into a position?

We often enter with two or three positions instead of one: the first from the 0.5 level or the first touch of the zone, the second after lower-timeframe confirmation or from a deeper retracement. There is one rule: the combined risk of all parts never exceeds the trade's risk. If the plan is 1%, that means, for example, 0.5% + 0.5% or 0.7% + 0.3%, not 1% each.

Scaling in lowers the cost of being wrong: if the first part gets stopped out, the second is never opened, and the loss is less than a full R. Scaling out works the same way: take partial profits at the first liquidity and move the rest to breakeven.

Risk management on a prop firm account

Prop firms have their own limits, and they are stricter than they look. Typically that is a daily drawdown of about 5% and a maximum drawdown of about 10% of the starting balance; the exact numbers depend on the firm. That is why our rules for prop accounts are:

  • risk per trade of 0.25–0.5% until the account is in profit;
  • a daily limit of two stops, after which trading is done for the day;
  • no trades ahead of major news if the firm's rules restrict them;
  • after passing the challenge, don't raise risk right away — build a cushion of a few percent first.

A prop account shows very quickly whether a trader has risk management. The good news: if you follow the rules in this article, the firm's limits almost never become a problem.

Common risk management mistakes

  • Size first, stop second. A stop fitted to the size you want isn't where the idea breaks.
  • Moving the stop. If price has reached your stop, the idea didn't work. Moving the stop turns −1R into −3R.
  • Revenge trading after a loss. Doubling risk after a loss is the fastest way to blow an account.
  • Ignoring spread and commission. On tight stops they can eat 10–20% of your risk.
  • Forgetting the point value. The same "1 lot" can cost 25 times more with a different broker.
  • Holding for the perfect target. The first liquidity in the direction of the move is a sensible place to take profit.

Risk management is step seven in our trading learning plan, but you need to apply it from your very first demo trade.

FAQ

How much of my account should I risk per trade?

We recommend 0.5–1% per trade and no more than 1% in total per day. On prop firm accounts it often makes sense to start at 0.25–0.5%: drawdown limits are strict, and a run of five losers in a row is normal even for a system that works.

Where should I put my stop loss?

Beyond the point where your idea is invalidated, the level that, once broken, means the trade scenario no longer makes sense. Usually that is the extreme you entered from or the edge of the higher-timeframe zone. Don't size the stop by an amount you are 'fine losing': place the stop off the chart first, then size the position to it.

How do you calculate risk in trading?

Multiply your account balance by your risk percentage: that is the amount you are prepared to lose. Divide it by the stop in points multiplied by the point value for one lot. The result is your position size. Round down to your broker's lot step.

Is there a position size calculator for GER40?

We are building a risk calculator for GER40, NAS100 and JP225 in the site's tools section. Until it launches, use the formula in this article and always check the point value against your broker's contract specification.

What risk-to-reward ratio do I need?

It depends on your win rate. At 1:2, you break even at roughly 33% winning trades; at 1:1, at 50%, before commissions. We more often take the first target at 1.5–2R than hold a trade for 4–5R.
