What is "ETH / BNB Amount" and "Max Percent"

“ETH Amount” is the amount of ETH that you are willing to spend to buy the target tokens.

The “Max Percent” is the maximum percentage of the target token which you can buy, another piece of information that you can grab from our New Contracts Telegram Channel.

If the number of tokens that you will receive from spending ETH Amount is more than your Max Percent setting, then the rest of your ETH will be returned to your accounts. This prevents transaction fails, a problem that Uniswap is plagued by.
