Are these trading calculators really free?
Yes, all calculators are 100% free with no signup required. They run entirely in your browser, so your data stays on your device.
Do these calculators work for forex and futures?
Yes. The position size calculator works for stocks, options, forex, and futures. Enter your account size, risk percentage, entry price, and stop loss to get the correct position size for any market.
How do I calculate my position size?
Divide your dollar risk (account size multiplied by risk percentage) by the per-share risk (the difference between your entry price and stop loss). For example, a $50,000 account risking 1% with a $2 stop equals 250 shares ($500 / $2).
What risk/reward ratio should I aim for?
Most professional traders aim for at least a 2:1 risk/reward ratio, meaning the potential profit is at least twice the potential loss. A 3:1 ratio is considered strong. Use our risk/reward calculator to check your ratio before entering any trade.
