If you trade — whether forex, crypto, stocks or CFDs — using a position-size calculator helps you set a consistent and safe risk level per trade instead of guessing. It lets you enter your account balance, decide how much of that balance https://trading.biz/position-size-calculator you’re willing to risk, set stop-loss distance, and get the optimal trade (lot/units/shares) size — so even a losing streak won’t blow up your account. This discipline goes a long way toward preserving capital, reducing emotional decision-making, and improving long-term survival in the markets. Even with good strategy, treat every trade as speculative and never risk more than you’re ready to lose.
