Hi,

Different types of symbols can have different types of commissions, you can fine commission types here: Models - cTrader Open API (spotware.github.io)

To correctly interpret a position/trade commission amount you have to know first what kind of commission the symbol uses.

Then based on symbol commission type you know what a position commission value represents, for symbols that uses PercentageOfValue you can get the actual percentage by dividing the position commission value to 100000.

In your case: 17500 / 100000 = 0.175

Thank you for the quick reply. I did check your models link before and I didn't find it anywhere that the amount should be divided by 10^5. I can only see 10^8 for non percentage types.

Hi,

It looks like the documentation is missing for PercentageOfValue commission type, we will add this to documentation of PreciseTradingCommissionRate.

When symbol commission type is PERCENTAGE_OF_VALUE divide the PreciseTradingCommissionRate to 10^5.
