to calculate the point (pip) price.
All currency pairs can be subdivided
into three logical groups - pairs with direct quote (EURUSD,
GBPUSD), pairs with inverse quote (USDJPY, USDCHF), and cross
rates (GBPCHF, EURJPY etc.).
1. The pip price for currency pairs with direct quote is calculated
according to the following formula:
[pip] = [lot size] × [tick
where [tick size] - is the smallest possible change in price,
for example for USDCHF and EURUSD it's 0.0001. For currency
pairs with direct quote the pip price is constant.
EURUSD. Lot size is 100,000, tick - 0.0001. [pip] = 100000
* 0.0001 = $10.00
2. For currency pairs with inverse quote:
[pip] = [lot size] × [tick size] / [current quote]
For currency pairs with inverse quote the pip price varies
depending on the current quote.
USDJPY. Lot size is 100,000, tick - 0.01. If current quote
is 129.20, [pip] = 100000 * 0.01 / 129.20 = $7.74
3. For cross rates:
[pip] = [lot size] × [tick size] × [base quote]
/ [current quote]
where [base quote] - the current base pair quote.
GBPCHF. The lot size is J62500; if the current quote is 2.3000
and the base GBPUSD quote is 1.4550, [pip] = 62500 * 0.0001
* 1.4550 / 2.3000 = $3.95.
