Why am I charged a taker fee when placing a limit order on Futures?

When you create a limit order, in addition to withholding the purchase amount and maker fee from the USDT balance, Pluang also withholds the taker fee as a CFX buffer for smooth transactions. Then when the order is executed, only the maker fee is charged and the withheld taker fee will be automatically returned to the USDT margin wallet without any deductions or withdrawals.

In addition, there is also an Aggressive Limit Order mechanism, where orders are immediately executed when sent to the exchange because the order automatically takes liquidity from the orderbook.
