Fees

Typically a brokerage charges a commission and then a much smaller, additional fee that covers regulatory and exchange fees. Wingman sums both together and classifies the total as "Fees".

In thinkorswim/TDA, commission and fees are derived from the Cash Balance section of the CSV file. Given the format, the file only reports commissions/fees on the order level, so it would show one for a group of multiple legs in one order. Therefore, we do not split up fees among the Legs. Instead, one Leg will be allocated the total fee amount, which is why you may see some Legs with $0 fees, and one in the Position having a large fee.
