The all-in-one trading risk toolkit trusted by serious traders. Calculate position size, lot size, margin, P&L and swap fees — across Forex, Stocks, Indices & Crypto — with mathematical precision. No guesswork. No blow-ups.
Precision Tools
Dynamic asset-class logic automatically selects the correct formula for Forex, Stocks, Indices & Crypto.
ℹ️ Dynamic logic: Forex → pip-based calculation with JPY 2-decimal correction · Stocks & Crypto → price-difference · Indices → point-value per contract.

💡 Fibonetics Tip
Professional traders risk 0.5–1% per trade. At 1:3 R:R you only need to be right 25% of the time to be profitable — precision beats prediction every time.
ℹ️ Formula: Required Margin = (Lots × Contract Size × Entry Price) ÷ Leverage · Free Margin = Balance − Required Margin · Margin Level = (Balance ÷ Required Margin) × 100%
Inputs
Results
Enter your position details to calculate required margin and margin level.
ℹ️ Formula: Gross P&L = (Exit − Entry) × Lots × Contract Size (Long) · Net P&L = Gross P&L − Commission − Swap Fees
Inputs

Enter your trade details to calculate gross and net profit or loss.
ℹ️ Formula: Total Swap = Swap Rate ($/lot/night) × Lots × Nights · Wednesday typically charges 3× daily rate. Always verify rates with your broker.
Inputs

Enter your broker's swap rates and hold duration to calculate total overnight cost.
💡 Swap Tip
Swap rates reflect interest-rate differentials between paired currencies. Always check your broker's current contract specification before holding positions overnight.

Serious traders don't guess — they calculate. Here's everything you need to understand about position sizing, pip values and professional risk discipline.
Dynamic pip-value logic handles JPY pairs, USD-quoted pairs and cross rates correctly — no manual adjustments or conversion errors.
Automatically switches between pip-based (Forex), price-difference (Stocks/Crypto) and point-value (Indices) logic when you change instruments.
Designed with funded account rules in mind — perfect for FTMO, MFF and The5ers traders who must stay within strict daily drawdown limits.
Calculate position sizes from your phone between analysis sessions. Full functionality across any screen size, any device, anywhere in the world.
Position sizing is the process of determining how many units to buy or sell — lots, shares or contracts — on a given trade, based on your defined risk tolerance. It is arguably the most critical discipline in trading, yet the most neglected by beginners.
While most retail traders fixate on finding the "perfect entry," professionals allocate equal or greater attention to position size. The reason is purely mathematical: two traders can take the exact same trade at the exact same price — but the trader with correct position sizing will survive a drawdown where the other will blow their account.
The foundational rule is simple: never risk more than you can afford to lose on a single trade. Most professionals benchmark this at 0.5–2% of total equity per trade.
A position size calculator automates the risk math so you can focus on trade analysis rather than arithmetic. Given your account balance, risk tolerance and stop loss distance, it computes the precise number of lots, shares or contracts to keep your risk at the exact level you've defined.
Without a calculator, traders make two recurring mistakes: risking a fixed lot size regardless of stop-loss width (causing wider stops to secretly risk far more money), or relying on intuition without accounting for pip-value differences across currency pairs.

Forex — Pip-Based Calculation:
Stocks — Price-Difference Calculation:
Indices — Point-Value Calculation:
These three terms describe the smallest standardised price movement for different asset classes:
This calculator detects your selected asset class and applies the correct logic automatically — including the JPY 2-decimal pip correction that many online calculators get wrong.
The Risk:Reward ratio compares the potential profit of a trade against its potential loss. A 1:2 R:R means you risk $1 to make $2. A 1:3 means you risk $1 to make $3.
Why this matters profoundly: your R:R and win rate together determine your expected value over time. At 1:2 R:R, a system only needs to win 34% of trades to break even. At 1:3, only 25%. This is why Fibonacci-based traders — who prioritise high-confluence setups at key price and time levels — can be consistently profitable with win rates well below 50%.
Enter a Take Profit level in the Position Size tab and the calculator computes R:R automatically. Target a minimum 1:2 R:R on every trade.

The Next Step
You now have the maths to size every position correctly. But position sizing is only half the equation — the other half is knowing exactly where to enter, where to place your stop, and where the market is mathematically likely to reverse next.
That's Fibonacci Price & Time Analysis. It's what Muneeb teaches in private 1-on-1 sessions to traders from 15+ countries — and it starts with a single free 15-minute call.
