How to Use Each Calculator
Each calculator serves a specific purpose in the trade planning process. Use them together for a complete picture of any trade before opening it.
Position Size Calculator
- Account balance
- Risk percentage (e.g. 1% or 2%)
- Stop loss in pips
- Instrument (EUR/USD, XAUUSD, etc.)
The correct lot size that limits your loss to your chosen percentage if the stop loss is hit.
Account: $5,000 · Risk: 1% ($50) · Stop Loss: 20 pips on EUR/USD → Result: 0.25 lots
Oversizing is one of the most common reasons traders lose accounts quickly. A position size calculator enforces discipline by making risk consistent across all trades.
Pip Value Calculator
- Instrument (currency pair or CFD)
- Lot size (e.g. 0.1, 1.0)
- Account currency (USD)
The exact USD value of 1 pip movement for your chosen instrument and lot size.
EUR/USD · 1.0 lot → 1 pip = $10.00 | EUR/USD · 0.1 lot → 1 pip = $1.00
Pip value varies by instrument and lot size. Knowing it precisely lets you calculate stop loss distances and take profit targets in dollar terms before entering a trade.
Margin Calculator
- Instrument
- Lot size
- Leverage (e.g. 1:100, 1:500)
- Account currency
The amount of margin (collateral) required to open and maintain the position.
1 lot EUR/USD · Leverage 1:100 → Required margin: $1,084 (at 1.08400 price)
Trading without knowing your margin requirement can result in unexpected margin calls. This calculator prevents overcommitting available margin across multiple open trades.
Profit / Loss Calculator
- Instrument
- Entry price
- Exit price
- Lot size
- Position direction (Buy/Sell)
Estimated profit or loss in USD for the trade, based on price movement.
Buy 1 lot EUR/USD at 1.08400, close at 1.08700 → Profit: $300 (30 pips × $10/pip)
Visualising the profit/loss before entering a trade helps you decide whether the risk-to-reward ratio justifies the position — a core step in any trade planning process.
Lot Size Reference Table
Lot size determines how many units of a currency or commodity you are buying or selling. Olla Trade supports micro lots from 0.01 — allowing precise position sizing for any account size.
| Lot Type | Units per Lot | Pip Value (EUR/USD) | Notes |
|---|---|---|---|
| Standard Lot | 100,000 units | $10.00 (EUR/USD) | Full-size position. Suitable for larger accounts. |
| Mini Lot | 10,000 units | $1.00 (EUR/USD) | One-tenth of a standard lot. Good for medium accounts. |
| Micro Lot | 1,000 units | $0.10 (EUR/USD) | Smallest standard unit. Suitable for small accounts and learning. |
Pip values are approximate and vary by instrument and current exchange rate. Use the calculator above for precise values.
Core Risk Management Rules
The calculator is only one part of disciplined trading. These risk management principles help protect your capital across all market conditions.
1–2% Risk Per Trade
Most professional traders risk between 1% and 2% of account balance on any single trade. This allows 50–100 consecutive losses before depleting an account — providing time to recover.
Minimum 1:2 R:R Ratio
For every $1 risked, target at least $2 in potential profit. A 1:2 risk-to-reward ratio means you only need to be right 34% of the time to break even over a series of trades.
Set Stop Loss Before Entry
Determine your stop loss price before opening any trade. This prevents emotional decision-making after the position is open and price moves against you.
Don't Move Stop Against You
Moving a stop loss further away from entry to avoid being stopped out increases your risk exposure. Only widen stops if your strategy explicitly calls for it.
Consider Correlation
Opening multiple positions in strongly correlated instruments (e.g. EUR/USD + GBP/USD) effectively multiplies your exposure. Account for this when calculating total risk.
Use the Calculator Every Time
Consistent application of position sizing calculators removes guesswork from trade sizing. Even experienced traders use them to maintain disciplined risk management.
Important: Trading calculators provide estimates based on inputs. Actual results may vary due to spreads, slippage, swap charges, and execution conditions. All trading involves risk of loss. Past performance is not indicative of future results.
