Twelve calculators for sizing trades, managing risk, and reading the market. Everything runs in your browser and updates as you type.
Risk & Position

Market Data
Position Size Calculator
Find the right lot size from how much you're willing to risk and your stop-loss distance.
0.33standard lots
Risk amount$10.00
Units33,333
Mini lots3.33
Micro lots33.3
$10/pip per standard lot applies to USD-quoted pairs. Gold, indices and JPY pairs differ — pick the instrument or enter a custom pip value, and confirm against your broker's contract specs.
How it works: risk amount = balance × risk %. Lot size = risk amount ÷ (stop-loss pips × pip value per lot). Risking 1–2% per trade keeps a losing streak from wiping out the account.
Pip Value Calculator
See what one pip is worth for your position, in your account currency.
$10.00per pip
Per standard lot$10.00
Per mini lot$1.00
Per micro lot$0.10
Units100,000
If your account currency differs from the pair's quote currency, set the quote→account rate (e.g. for a EUR account on USD-quoted pairs, the USD→EUR rate).
How it works: pip value = pip size × units, converted to your account currency. For USD-quoted pairs with a USD account, that's a flat $10 per pip per standard lot.
Risk / Reward Calculator
Check your reward-to-risk ratio and the win rate you'd need to break even.
1 : 2.33reward : risk
Risk distance300 pts
Reward distance700 pts
Breakeven win rate30.0%
Potential reward—
Breakeven win rate is the share of trades you must win just to not lose money at this ratio. A 1:2 setup only needs ~33% winners to break even.
How it works: risk = |entry − stop|, reward = |target − entry|, ratio = reward ÷ risk. Breakeven win rate = 1 ÷ (1 + ratio).
Risk of Ruin
Simulate thousands of trade sequences to estimate the odds your strategy blows past a loss limit.
—probability of ruin
Median outcome—
Expectancy / trade—
Simulations run5,000
Survived—
A Monte-Carlo estimate using fixed-fractional sizing (you risk the same % of your current balance each trade). Negative expectancy + high risk % is what drives ruin — not bad luck.
How it works: each run plays out your trades one by one, growing or shrinking the balance, and counts as "ruin" if it ever falls past your loss limit. Run across 5,000 sequences, the share that fail is your risk of ruin.
Drawdown Recovery
See the gain you need to claw back a loss — the maths that makes big drawdowns so dangerous.
25.0%gain needed to recover
Balance after drawdown$800.00
Amount to recover$200.00
Losses and gains aren't symmetric: a 50% loss needs a 100% gain to get back, and a 90% loss needs 900%. Protecting capital beats chasing it back.
How it works: required gain % = (1 ÷ (1 − drawdown)) − 1. The deeper the hole, the steeper the climb — which is the whole argument for tight risk control.
Profit / Loss Calculator
Estimate the result of a trade from entry, exit and size.
$500.00profit / loss (quote ccy)
Pips gained50
Units100,000
Result is in the pair's quote currency. Spread, commission and swap aren't included — they reduce real-world results.
How it works: P/L = (exit − entry) × direction × units. A long profits when price rises; a short profits when it falls.
Margin Calculator
Work out the margin a position ties up at a given leverage.
$1,085.00required margin
Notional value$108,500
Units100,000
Leverage1:100
Margin %1.00%
Margin shown is in the quote currency. Higher leverage lowers margin but not your risk per pip.
How it works: notional value = units × price; required margin = notional ÷ leverage.
Leverage Calculator
See the real leverage a position puts on your account.
1 : 108.5effective leverage
Notional value$108,500
Units100,000
Effective leverage is how much market exposure you control per dollar of equity — often very different from the max leverage your broker allows.
How it works: effective leverage = notional value ÷ account equity. Keeping it modest is one of the simplest ways to survive long enough to compound.
Compounding Calculator
Project how an account grows when you reinvest a steady gain each period.
$1,795.86ending balance
Total profit$795.86
Total return+79.6%
Compounding assumes you hit the same gain every period and reinvest it. Real returns vary; treat this as a model, not a promise.
How it works: ending balance = start × (1 + gain%)^periods. Small steady gains compound surprisingly fast — and so do steady losses.
Fibonacci Calculator
Retracement and extension levels between a swing high and low.
61.8% and 38.2% are the most-watched retracements; 161.8% is a common profit-target extension.
How it works: each level sits a Fibonacci fraction of the high-to-low range away from the swing point. In an uptrend, retracements drop from the high; in a downtrend, they rise from the low.
Pivot Points Calculator
Standard floor-trader pivots from the previous period's high, low and close.
Price above the pivot (PP) leans bullish, below leans bearish. R/S levels act as intraday support and resistance.
How it works: PP = (high + low + close) ÷ 3, with resistance and support levels stepped out from it. Widely used for intraday bias and targets.
Forex Market Hours
Which trading sessions are open right now, live in your browser.
Loading clock…
Session times are approximate and shift with daylight saving. The London–New York overlap (roughly 13:00–17:00 UTC) is usually the most active and liquid window.
How it works: your device clock is converted to UTC and checked against each session's hours. The market trades 24 hours from the Sydney open Monday morning to the New York close Friday evening.
Risk warning. These tools are for educational purposes only and are not financial advice. Results depend on the values you enter and your broker's contract specifications — verify against your platform before trading. Trading forex, CFDs and synthetic indices carries a high level of risk and you can lose more than your deposit.
Still to wire up (need a data feed): a live currency converter, a correlation matrix, and an economic calendar all need external data. Easiest paths: a free FX-rates API (e.g. exchangerate.host or open.er-api.com) for the converter; computed correlations from a historical-price API for the matrix; and an embeddable economic-calendar widget (Forex Factory / Investing.com / a TradingView widget) for the calendar. Everything above runs with no data feed at all.
