How Much Should I Risk per Trade

Short answer

Size every position from the stop, not from leverage: position size = (account × risk %) ÷ stop distance %. Risking 1% of a 1,000 USDT account with a 4% stop gives a 250 USDT position. Leverage changes the margin locked, not the loss at the stop, as long as your liquidation price sits beyond the stop.

Key facts

Formula	Size = Account × Risk% ÷ Stop distance%
Example	1,000 × 1% ÷ 4% = 250 USDT
Same risk, 2% stop	500 USDT position, same 10 USDT loss
10 losses at 1% risk (compounded)	about −9.6% of account
10 losses at 5% risk (compounded)	about −40% of account

Why start from the stop instead of leverage?

Decide where the idea is wrong first. That is your stop. The distance from entry to stop, multiplied by size, is what you lose if you are wrong. Leverage only decides how much margin the exchange locks, so it is the last choice, not the first.

Initial margin = notional ÷ leverage. So the same 250 USDT position locks less margin at 10x than at 5x. The loss at a 4% stop is still 10 USDT in both cases, because profit and loss depend on size and price change, not leverage. Before placing the trade, check that the liquidation price the exchange shows is further away than your stop.

How do I calculate position size?

Position size = (account × risk %) ÷ stop distance %. With 1,000 USDT, 1% risk and a 4% stop: 10 ÷ 0.04 = 250 USDT. With a tighter 2% stop the same risk allows 500 USDT. The loss at the stop is 10 USDT either way.

Stop distance % = |entry − stop| ÷ entry. The 250 USDT result is notional (position value), not margin. To enter it as a coin quantity, divide 250 by your entry price. Then round down to the exchange's quantity step so you never exceed your risk.

What are R-multiples and why use them?

If you risk 10 USDT and make 20, that is +2R. If the stop hits, that is −1R. R makes trades of different sizes comparable and shows whether winners pay for losers. Logging each closed trade in R, rather than in USDT, lets you compare results across account sizes and over time.

How bad can a losing streak get?

Even a method with a real edge can lose many times in a row. Ten straight losses at 1% risk cost about 9.6% of the account. At 5% risk they cost about 40%. Sizing decides whether you are still trading when the bad run ends. Keep total open risk capped too: add up the planned stop loss on every open position, because several positions can lose at the same time.

How do fees and funding fit into position size?

Fees and funding are part of the loss when a stop is hit. Add the round-trip fee and expected funding for the planned holding time to the stop distance before sizing. On short holding times this changes little. On trades held for days it can matter.

In practice, use (stop distance % + round-trip fee % + expected funding %) as the denominator. A larger denominator gives a smaller position, so the total loss at the stop stays at your chosen risk. Check your fee tier and the current funding rate on the contract's info page before sizing.

FAQ

What risk percentage should I use?

There is no single correct number, and this article does not recommend one. Many risk-aware traders use 0.5–2% per trade. Smaller percentages make a long losing streak easier to survive, as the 1% and 5% examples show. The right number depends on your goals and tolerance.

Does high leverage mean high risk?

Risk is set by size and stop distance. Leverage mainly changes margin use and liquidation distance. Higher leverage puts liquidation closer to entry, so a bad move can close the position before your stop. The CFTC's customer advisories on digital asset risks are a useful official read on this.

Can I lose more than 1R?

Yes. A stop-market order becomes a market order once triggered and fills at the best available price, which is not guaranteed. Gaps and slippage can fill it beyond the stop level, so real losses can exceed 1R.
