In 2015, Fidelity became the first to begin showing per order and cumulative price improvement across each account (Charles Schwab became the second broker to do so in 2018). For month-to-date, year-to-date, and previous 12-month periods, customers can see exactly how much they paid in commissions, how many trades received price improvement, and the total price improvement. Price improvement means a buy order was executed lower than the best ask or a sell order was executed higher than the best bid at the time of the trade.
