What Each Tool Does

🔮
Crypto Perpetuals Calculator
Most traders size positions by feel — and pay for it. This calculator takes your account balance, risk percentage, entry price, and stop loss and outputs the exact notional position size, minimum leverage required, estimated liquidation price, and total round-trip fees.

Fee rates differ massively by exchange: MEXC charges 0.01% taker vs 0.05–0.055% on Binance/Bybit. On a $50,000 notional trade that's a $20–$22 difference per round trip — directly out of your risk capital.

Trading Equity Curve Simulator
An equity curve simulator runs a Monte Carlo simulation of your trading strategy using your stated win rate, risk-to-reward ratio, and risk per trade. It shows you the realistic range of outcomes — including the maximum drawdown you should expect even with a profitable edge.

Use it to stress-test your strategy before going live. A 55% win rate with 2R sounds solid until you see a 200-trade simulation hit a 28% drawdown through a cold streak.

Forex Position Size Calculator
Enter your account balance, currency, risk %, entry, and stop loss distance — the calculator outputs the exact lot size, pip value, and broker commission for your trade. Supports all major pairs, JPY crosses, gold (XAU/USD), and indices.

Commission is compared live across Fusion Markets ($4.50/lot), IC Markets ($7.00/lot), and IG (spread-based). Knowing your cost before entry is not optional — it is part of the trade.

Frequently Asked Questions

How do I calculate the correct position size for crypto perpetuals?
Enter your account balance, the percentage you're willing to risk, your planned entry price, and stop loss price. The calculator derives the notional position size (total contract value) and the minimum leverage needed to open it — so you use only the leverage the trade actually requires, not the maximum available.
Why do exchange fees matter so much in crypto trading?
On a perpetuals trade with a 1% stop loss and $1,000 risk, you might open a $100,000 notional position. At 0.05% taker fee (Binance), the round-trip cost is $100 — that's 10% of your risk capital gone before price moves. MEXC's 0.01% taker rate cuts that to $20. Over hundreds of trades, this difference is the difference between profitability and slow account death.
What is an equity curve simulator and why should I use one?
An equity curve simulator applies your win rate and risk-to-reward ratio across a random sequence of trades (Monte Carlo method), showing you the realistic distribution of outcomes including worst-case drawdowns. Most traders overestimate how consistent their results will look — simulating 500 trades at 55% WR / 2R will show you the losing streaks you should psychologically prepare for before they happen.
Are these tools free to use?
Yes. All three calculators — Crypto Perp, Equity Curve, and FX Calculator — are completely free to use with no account required. They run entirely in your browser; no data is sent to any server.
