31 professional-grade tools for planning trades, managing risk, and analyzing performance across stocks, forex, and crypto — free, no sign-up required.
Disclaimer: Trading financial instruments involves risk, and every result on this page is for educational purposes only. Nothing here is financial advice or a recommendation to buy or sell any instrument.
Position sizing
Deciding how much to trade based on your risk budget and stop distance, so no single loss hurts the account.
Risk-adjusted return
Judging a result by how much risk was taken to earn it — Sharpe, Sortino, and drawdown all measure this.
Compounding
Letting returns stay in the account so each period earns on a larger base — the engine behind long-term growth.
✗ Grabbing a calculator mid-trade to justify a decision you already made
✓Run the numbers before you enter. A calculator used to rationalize an emotional trade is not risk management.
✗ Using gross figures while ignoring fees and slippage
✓Costs change the answer. Keep the fee inputs honest and always read the net result.
✗ Treating a projected result as a prediction
✓Every output is educational math, not a forecast. Real markets add volatility, gaps, and costs the model cannot see.

Run the numbers first
Enter the trade into the calculator before you place it. If the math looks poor at your target and stop, the trade is poor — no matter how good the story feels.
Keep inputs honest
Realistic fees, spreads, and volatility inputs keep the output useful. Flattering assumptions only flatter the calculator.
Move from calculator to backtest
A single calculation is a snapshot; a backtest shows how a rule performs over hundreds of trades. Use both.
Yes — all 31 calculators are free to use with no account and no sign-up. The calculators sit in the free plan of the platform, alongside limited monthly backtests and practice sessions.
No. Every calculator on this page works anonymously in your browser. You only need an account for features that save state across visits, like saved backtests and strategy plans.
The suite covers US stocks, Hong Kong stocks, forex, and cryptocurrency. Each calculator adapts its units and formulas to the market, whether that is shares, lots, or coins.
The calculators implement standard, widely used formulas from risk management and financial mathematics — such as position sizing, Sharpe ratio, and drawdown. Each tool explains its formula and any assumptions so you can verify the math.
A few tools marked “Live data” pull current prices or rates, while the rest use the numbers you enter. Both are educational: they help you plan and learn, and none of them constitute investment advice.
All calculators are provided for educational purposes and do not constitute investment advice. Trading involves substantial risk of loss.
