Your copy trading portfolio may differ from the Hyperliquid Leader’s portfolio for several reasons: unsupported markets on BitMEX, differences in trading fees and funding fees, slippage between execution venues, timing delays in position synchronisation, and proportional sizing based on your committed capital. These are normal operational factors, not errors.
What Causes Differences Between My Portfolio and the Leader’s?
Several factors can cause your copy trading portfolio to differ from the Hyperliquid Leader’s actual portfolio on Hyperliquid.
Unsupported markets. If the Hyperliquid Leader trades a market that is available on Hyperliquid but not supported on BitMEX, that trade is not replicated. The market’s liquidity might not pass BitMEX criterias (Insufficient liquidity conditions are when either the Bid/Ask spread exceeds 1% or the Open Interest is below $500,000.)
Trading fees. BitMEX trading fees apply to your replicated trades. These fees are different from the fees the Hyperliquid Leader pays on Hyperliquid. The fee difference affects your net PnL relative to the leader’s.
Funding fees. Perpetual contracts involve periodic funding fee payments between long and short holders. Funding rates differ between BitMEX and Hyperliquid. These differing rates contribute to PnL divergence over time.
Slippage. Trades execute on two different venues (Hyperliquid and BitMEX) with different liquidity profiles. The price at which your trade executes on BitMEX may differ slightly from the price the leader achieved on Hyperliquid.
Execution timing. There is a small delay between the Hyperliquid Leader’s trade execution on Hyperliquid and the replication of that trade on BitMEX. During volatile markets, price can move during this delay.
Proportional sizing. Your positions are sized proportionally to your committed capital. The Hyperliquid Leader may have a significantly different capital base, leading to different rounding and position sizes.
Are Portfolio Differences a Cause for Concern?
Portfolio differences between your account and the Hyperliquid Leader’s are normal and expected. They result from standard market mechanics rather than feature errors.
Minor PnL differences are typical in any copy trading system where trades execute across different venues. BitMEX carefully vets supported trading pairs to minimise slippage on liquid markets.
If you observe consistently large differences, review whether the Hyperliquid Leader is trading in markets not supported on BitMEX. This is the most common cause of significant portfolio divergence.
