There have been many times when I've looked at a trade that isn't selling and wanted to lower the price, but having to cancel the trade and recreate it all over again just for that is very tedious. I would instead propose the ability to edit a trade buyout at any time.

As far as I'm aware this wouldn't be difficult to code since it's just changing numbers and maybe there could be a cooldown on how often you can edit it, similar to bumping? But I'm open to hearing what other people think about that.
