The calculation is identical to the calculation for a five-digit quotation, with only the value of the minimum quotation changing from 0.00001 to 0.0001.
Example: Deposit currency USD. Trader opens a position on the pair EUR/USD, the opening price is 1,2290, therefore, the cost of 1 point will be:
for 0.10 lot = 0.10 * 100,000 * 0.0001 = 1.00 USD;
for 0.01 lot = 0.01 * 100,000 * 0.0001 = 0.10 USD.
