In forex trading, a “pip” (percentage in point) is the smallest standard price move for a currency pair — typically the fourth decimal place for most pairs (0.0001), or the second decimal place for yen pairs (0.01). Understanding pip value is essential for prop firm traders because your risk per trade must be calculated in account currency, not in pips, to stay within your firm's drawdown limits.
Pip value is not fixed — it changes depending on the currency pair you are trading, your account currency, and the size of your position. For a standard lot (100,000 units) on EUR/USD with a USD account, one pip is worth exactly $10. For GBP/USD, one pip is also $10 on a standard lot, but for USD/JPY it is approximately $9.09 (because of the yen exchange rate). For less common pairs, pip value must be calculated using the counter currency exchange rate.
This matters enormously for prop firm traders: if you set a stop loss at 20 pips on EUR/USD and another at 20 pips on GBP/JPY, the actual dollar risk is different for each trade. Many traders fail challenges because they treat all 20-pip stop losses as identical when they are not.
Forex positions are measured in lots. A standard lot is 100,000 units of base currency. A mini lot is 10,000 units (0.1 lots). A micro lot is 1,000 units (0.01 lots). Most retail prop firm accounts allow trading from 0.01 lots upwards.
For a $50,000 prop account with a 1% risk per trade rule ($500 maximum risk), and a 25-pip stop loss on EUR/USD, the correct position size is 2 standard lots (2 × $10 per pip × 25 pips = $500). Getting this calculation right on every trade — not just estimating — is a fundamental discipline that separates consistent funded traders from those who routinely over-risk.
Every forex trade has a spread — the difference between the buy (ask) and sell (bid) price. This spread is paid immediately when you open a position and represents a cost that comes off your account. For a prop firm challenge, spreads are a real and constant drag on your account. During news events, spreads can widen dramatically — a normally 1-pip EUR/USD spread can temporarily widen to 10+ pips, which means your stop loss could be hit by a spread spike rather than genuine price movement.
Always factor the spread into your risk calculation. If your stop is 20 pips and the spread is 1.5 pips, your effective risk per trade is 21.5 pips worth of account exposure from the moment you enter.
Most prop firms restrict trading during major news events, particularly on forex pairs. NFP (Non-Farm Payrolls), FOMC decisions, and CPI releases are the most commonly restricted events. The restriction typically applies for 2–5 minutes either side of the event. Violations can result in trades being voided or accounts being terminated — even if the trade was profitable.
