On the cTrader platform TNXTrade charges a commission fee of $45 per million USD traded. If your account is denominated in a currency other than USD you will need to convert this figure. TNXTrade’s Commission Calculator does this for you. Simply enter the size of your trade, the currency pair you are trading, your account currency, and click ‘Calculate’. The Commission Calculator will then determine how much commission you will pay for opening and closing the position.
The Commission Calculator works as follows:
Trading 100,000 GBP/JPY with an account currency in EURO
0.000045 * 100,000= £4.50 (Base currency of the pair traded)
To convert to EUR we must divide by the EUR/GBP rate (0.798)
