Limit Orders Can Still Incur Taker Fees, Trading Data Shows

A developer of automated trading software examined whether a limit order that fills at exactly its limit price is charged the maker or taker fee. He explains that a fill better than the limit typically means the order consumed an existing resting offer, making the buyer or seller the taker. Analysing about 6,200 live Bybit perpetual futures executions from late August to late October 2026, he found that roughly three in four fills exactly at the limit were charged taker fees. The finding matters for bots that trade repeatedly, since a mistaken fee assumption in backtests compounds across every trade. The data came from two accounts, so the proportion reflects those accounts over that period rather than bots in general.
