Position size calculator

The amount at risk is your balance times the percentage you chose. It is the only decision genuinely under your control before entry: neither the market nor the broker changes it.

The size then comes out of one division: amount at risk ÷ (stop distance in pips × pip value per unit). The pip value is converted into your account currency at the current rate.

Exposure and leverage are not decoration. A very tight stop produces a huge size: the risk stays as intended, but the exposure can exceed what the broker will finance — and liquidation then comes long before the stop.

The spread. The real loss on a stop hit is slightly larger than the displayed distance, by the gap between bid and ask at the moment of exit.

Slippage. A stop is not a price guarantee: on an economic release or a weekend gap it fills wherever the market is, sometimes much further away.

Financing costs on positions held overnight, and any commission your broker charges.
