The only calculator that tracks all your open trades at once. Enter your total portfolio exposure, then validate whether a new position fits inside your risk limits before you take it.
Your risk management is within safe parameters
Leverage above 5x significantly increases liquidation risk. Your stop loss should trigger before liquidation. Lower leverage = safer trading.
This trade meets all risk management criteria
Your liquidation price is within 20% of entry. Consider reducing leverage.
The Trading Calculators page answers a single-trade question: "How much should I risk on this one trade?" That's useful — but it's blind to everything else you have open. Risk Calculator Pro answers the harder question: "Given everything I already have on, can I afford to take this?"
Use both together: Set your account-level rules here first, then go to the Trade Calculator tab to size individual positions — it pulls your portfolio settings automatically.
Start in the Portfolio Overview tab. Enter your total account balance and choose a risk percentage per trade. 1%–1.5% is the professional range — at 1% you can absorb 100 consecutive losses before wiping out. Use the quick-select badges (🟢 1% / 🟡 1.5% / 🔴 2.5%) to apply presets instantly.
In the Open Positions card, enter how many trades you currently have open and the total dollars at risk across all of them. This is not your position sizes — it is the actual amount you stand to lose if every stop loss hits simultaneously.
The status banner and metrics update instantly. Green means you have capacity to take new trades. Yellow means you're approaching your limits. Red means stop — adding another position would breach your risk rules. The Risk Exposure bar shows what percentage of your total allowed risk budget is currently committed.
Switch to the Trade Calculator tab. Enter your entry price, stop loss, direction, and take-profit target. With Auto Position Size enabled, the calculator sizes the trade so your maximum loss exactly matches your per-trade risk rule — no manual arithmetic, no guessing. You get an instant Approved or Rejected verdict.
The verdict checks three things automatically: (1) Does this trade breach your per-trade risk limit? (2) Is the risk:reward ratio worth taking? (3) Is the liquidation price dangerously close to entry? All three must pass for an Approved status.
Total $ at Risk is the sum of all your active stop loss amounts — the worst-case loss if every open position hits its stop at the same time. For each trade: multiply the position size by the stop loss percentage. Add all results together. This is different from your total position value. A £10,000 BTC position with a 2% stop loss has £200 at risk, not £10,000.
Leverage controls your position size and the margin you need to hold it — it does not change how much you lose if your stop hits. A properly placed stop loss closes the trade before liquidation. Your risk is always determined by your position size multiplied by the distance to your stop, regardless of leverage. What leverage does affect is your margin requirement and liquidation price — which is why the calculator shows both separately and warns you when liquidation gets dangerously close to entry.
1%–2% is the professional range. At 1% risk per trade with five concurrent positions, your maximum portfolio drawdown in a worst-case wipeout of every position simultaneously is 5%. That leaves 95% of your capital intact to continue trading. Risking 3% or more compounds quickly — five open trades at 3% each puts 15% of your portfolio at risk in a single correlated market move, which is the kind of drawdown that psychologically destroys most traders.
Rejected means at least one rule is broken: risk exceeds 3% of portfolio, risk:reward is below 1.5:1, or liquidation price is within 20% of entry. Warning means the trade passes minimum criteria but is marginal — risk is between 2%–3%, R:R is below 2:1, or liquidation is within 33% of entry. Approved means the trade passes all three checks. You can still take a warned trade — but you should know why it's flagged before you do.

The Position Size Calculator gives you the correct size for one trade in isolation. It doesn't know about any other positions you hold. Risk Calculator Pro sits above it — it enforces portfolio-level discipline across multiple concurrent positions. Think of it as the gatekeeper: use this tool to check whether you're allowed to take a trade at all, then use the Position Size Calculator for detailed P&L and fee modelling on that specific entry.
