CopyFi is a no-code platform designed for building personalized strategies in copy trading. Unlike traditional copy trading, which replicates another trader's actions directly—thus transferring their position sizes, leverage, and potential errors—CopyFi integrates the user's own set of rules to create a buffer between the trader's signals and the user's account. This allows users to specify which traders to follow, select preferred markets, determine position sizes, set leverage limits, and decide when to halt trading activities. The system utilizes a user-friendly visual block interface for logic assembly, eliminating the need for coding, while also allowing strategies to be tested on actual market data prior to any financial commitment. Once finalized, the same strategy operates on the user's chosen brokerage or exchange account. Importantly, CopyFi is a non-custodial service, ensuring that users maintain control of their funds in their own exchange accounts, with API keys that permit only read and trade actions, thus safeguarding against withdrawal risks. This approach empowers traders to engage confidently in copy trading while retaining full oversight of their investments.
