There are "maker subsidies" and "taker fees" on this market. The taker fees apply when you match an existing order on the order book, whereas the maker subsidy happens when you place an unmatched order that is matched later. The maker subsidies are .025 times the price, times the potential profit (e.g., Maker Subsidy per share = .025*Price/100*(1-Price/100)). The taker fees are .075 times the price, times the potential profit (e.g., Taker Fee per share = .075*Price/100*(1-Price/100)). Thus, the maker subsidy to buy 100 shares at 20 cents would be: 100*.025*(20/100)*(80/100) = $0.40, and the taker fee would be $1.20. The full fee schedule is here.
