Copy
A share of your account follows a whale's future trades, until you stop.
Allocation
That share is your allocation.
Your allocation mirrors the whale's account in proportion: when it puts 30% of its account into a trade, the copy puts 30% of your allocation.
Stops and exits
Every trade gets a stop where the whale's own position would be in trouble, and the copy closes a trade when the whale does.
Leverage cap
Each trade goes at the whale's leverage, up to Hyperliquid's maximum for the coin.
Largest exposure
Your allocation is the most this copy can ever have open, in position size; each trade's stop keeps a single loss far below it.
Pause and stop
Pause stops new entries and lets open ones run to their exit. Stop closes everything now, or lets open trades finish. Mirroring the whale's positions that are already open is off unless you turn it on.
