Perpetual/Delivery contracts: fee rate fields

[LKresta]

Hello there,

I'd like to ask about fee rate fields in https://www.gate.io/docs/developers/apiv4/en/#contract. There are two fee rate fields, maker_fee_rate and taker_fee_rate. What is their semantics, are they just fees effective for current trade (identified by trade_id field)? Or are they in any way related to fees effective for my user account (https://www.gate.io/fee)?

Cheers,
L.
