Currency conversion is done via the execution of a Forex order on the pair composed of the reference currency of your portfolio and the currency to convert.
It is subject to the same fees as the execution of a Forex order on the same pair and for the amount to be converted.
Please note that there may be a small residual amount in the currency to be converted after the conversion due to market fluctuations among other things.
Any residual amount less than 5 USD (in absolute value) or equivalent will be converted into the reference currency after a few days.
Before performing a conversion operation for a given currency, you must first close any Forex positions concerned by this other currency.
The cash converted is calculated based on the cash available in the different currencies converted into the reference currency at market price, not including conversion fees.
