CopyFi

Most copy trading mirrors a trader one to one, so the follower inherits that trader's leverage and position sizing along with their entries. CopyFi puts the follower's own rules between the signal and the account: how much size a single copied trade may use, a leverage ceiling the copied trader cannot push past, direction and per-asset filters, and kill switches that end a session on a P&L or drawdown limit.

Those rules are enforced by software on every copied order before it reaches the exchange, and they are assembled from visual blocks without writing code. The platform is non-custodial, so funds never leave the user's own exchange account and the API key carries read and trade permissions only, never withdrawal. A testnet mode lets users run the entire setup on paper money against live market prices before connecting real funds. CopyFi executes on Phemex today, in both live and testnet accounts.
