what is a trading rebate fee and how to use it

Got it — you’re saying:

Binance gave you a trading fee rebate (maybe from a promotion, voucher, or as cashback).

It shows as "In Use" in your wallet.

But you can't open trades with it.

This is a common issue. Let me explain what's happening:

1. Fee rebates are not usable as trading balance.

The rebate (cashback) you get is only used to pay trading fees, not to open or fund new trades. That's why it shows In Use — it's reserved for covering your future trading fees automatically.

2. You still need real funds to open a trade.

You must have USDT, BTC, or whatever currency you're trading with, separately available in your spot or futures wallet.

3. What you can do:

Deposit or transfer real trading funds into your wallet.

Then open trades normally — the rebate will automatically be used to discount the fees when you trade.

You don't need to manually use the rebate. It applies in the background.

Quick Example:

You get $10 rebate voucher.

You open a $1000 trade.

Normally, maybe $1 fee is charged.

Now, Binance uses the rebate to pay the $1 fee.

Your $1000 trading is normal; your balance is untouched by fees until the rebate is exhausted.

In short: You can't trade with rebate balance; you can only pay fees with it.
