Enter your account size, entry price, and stop-loss to instantly calculate the correct position size for any risk level. Set a target exit price to see your R:R, or pick a desired R:R and get the target price.
Risk (Stop Loss)
Professional traders typically risk 1-2% of their account per trade. This ensures no single loss can significantly damage the account. Even a string of 10 losses only draws down 10-20%.
The distance between your entry and stop-loss determines how many units you can buy. A wider stop means fewer units (smaller position) for the same dollar risk. Tighter stops allow larger positions but get hit more often.
A 1:2 R:R means you stand to gain $2 for every $1 risked. With a 1:2 ratio, you only need to win 34% of trades to break even. Higher ratios give your strategy more room for losing streaks.
When position value exceeds account size, you are using leverage. A 5x leveraged position means a 20% adverse move wipes out the account. Always know your effective leverage before entering a trade.
