Short answer
When you copy a trader, you set a maximum amount per trade, a daily budget and optional filters such as skipping tokens that fail the rug check. You can stop copying at any time.
Copying mirrors a trader's buys and sells from your own wallet. Your per-trade cap means a trader's $5,000 buy becomes, say, a $20 buy for you. Your daily budget stops copying for the day once it's used up, however active the trader is.
Filters let you skip trades you'd never make yourself, for example tokens that fail the rug check or have very little liquidity. Each copied trade pays the same 0.5% fee as a manual one.
Limits control how much you can lose. They can't make a trader profitable. Check a trader's median copier P&L before you start.
