L1.4 — Lot Size Tools and Broker-Specific Calculations
Pip value varies by instrument, lot size, and account currency. On EURUSD with a USD account, one standard lot = $10 per pip. On XAUUSD, one standard lot = $100 per dollar move ($1 per pip if pips are the smallest increment). On GBPJPY with a USD account, the pip value depends on the current USDJPY rate. Calculating this manually every trade is error-prone. Use a position sizing calculator or build the formula into your pre-trade process.
Most trading platforms include a position size calculator or have a formula available. MetaTrader 4 and 5 display the pip value per lot in the contract specification. Verify the pip value for each instrument you trade at least once per quarter — it can shift as exchange rates change.
The goal is to remove calculation friction from the execution process. If calculating position size takes more than 30 seconds, you will skip it under pressure. Automate or template the calculation so it is a mechanical 10-second step, not a cognitive burden that gets skipped when you are eager to enter.
