Should I expect any additional fees when buying or selling stocks?

When selling stocks, SEC and TAF regulatory fees will apply. These fees can vary from time to time, but currently stand at .000021/$1 sold for the SEC fee and $0.00019/share for the TAF fee. When selling stock short, SEC and TAF fees will apply and there is the potential for a short rebate fee if Tradier Brokerage has to pay to borrow the stock.
