Balancer Pools are extremely customizable, and each pool can have a different fee. Some pools had dynamic fees set by Gauntlet which have been removed due to inefficacy. Or alternatively create your own dynamic fee pools that are set by something like https://volmex.finance/.

For a research project to be successful, please include:

1. A detailed explanation of how to simulate real-world trading activity in response to dynamically changing fees.
2. What factors would be considered a trigger to change the fee and is this checked on a trade by trade basis, daily, weekly etc
3. What pools would be most suitable for a dynamic fee
4. How would triggers be monitored and fee change completed (something like Autonolas or otherwise?)
