With this new feature enabled you will be protected from getting MEV'd, but pay a tiny extra fee per trade, to avoid this from happening.
MEV explained: MEV stands for Maximum Extractable Value.
In short basically some smart nerd will sit there and use a software to put a buy order in BEFORE yours / other large buy orders, to get a better price.
He then sells immediately after your buy or the large buy order, to sell for a small profit. They do this at scale with thousands of transactions.
