Copy trading includes several safeguards to protect copiers during the alpha period.

​
Deposit Limits

These limits apply to the total allocation per copy profile — your initial amount plus any funds you add later must stay within the range. If you’re copying 3 different traders, each profile has its own $50–$10000 range. Partial withdrawals must leave at least $50 in the profile; otherwise withdraw everything, which stops the copy.
If a brand-new Hyperliquid sub-wallet has to be created for your copy, a one-time Hyperliquid network fee of around $1 may be deducted when the wallet is activated. If you’ve copy traded before, Legend reuses a previous copy wallet and no fee applies.

​
Order Limits

If a proportional order would result in less than $10 of notional value, it’s skipped. This can happen when copying a trader with a much larger account — very small percentage moves may not meet the minimum.

​
Leverage

Your copy wallet mirrors the trader’s leverage and margin mode (isolated or cross) exactly — there’s no separate leverage cap to set. Risk is controlled by your allocation size, since every position is scaled down proportionally to the amount you allocated.

​
Profit Share

Traders can charge a profit share of up to 20% on the gains they generate for you. The rate is shown before you start copying and locked in at that point — a later rate change by the trader doesn’t affect your existing copy. It applies only to winning trades and is charged when a winning copied position closes. Positions that close at a loss incur no profit share.

​
Asset Restrictions

To protect against slippage and market manipulation, copy trading restricts which assets are mirrored:
  • Open interest threshold — Assets with less than $5M in total open interest are not copied
  • AUM-to-OI cap — The total copy trading capital on any one asset is kept under 1% of its open interest. If copiers would collectively exceed that, copied positions on the asset are scaled down to fit (or skipped when there’s no room left).
These restrictions are evaluated in real-time for each order.

​
Pre-Existing Positions

By default, a trader’s already-open positions are not mirrored when you start copying. This prevents you from entering a trade mid-way — for example, being on the wrong side if the trader sells an existing long. The trader’s original stake in an asset is never copied; if they add to a pre-existing position after you start, only the added portion is mirrored proportionally. This is the Only copy newly opened positions toggle, on by default. Turn it off at setup if you’d rather also mirror the trader’s current open positions.

​
Withdrawing Funds

You can withdraw from an active copy at any time:
  1. Partial withdrawals are checked against your copy wallet’s live value — if you’re in profit, you can withdraw gains too. Your positions scale down proportionally after the withdrawal. The amount must leave at least $50 in the profile.
  2. Withdrawing everything stops the copy (see below).
Withdrawals are sent back to your main wallet automatically. If most of your balance is deployed in open positions, the transfer completes as soon as the funds are freed up.

​
Stopping a Copy Profile

When you stop copying a trader:
  1. All open positions in your copy wallet are closed with market orders
  2. After positions settle, your remaining USDC is automatically transferred back to your main wallet
  3. The profile is marked as stopped — no further orders will be placed
