Tracking error

Tracking error is the accumulated divergence between a mirrored account's result and the leader's own.

In short

Tracking error is the difference between what a follower realises and what the copied trader realised, driven by replication lag, fill prices, fee structure, funding accrual timing and any sizing or leverage caps applied to the follower.

Why it is expected, not a malfunction

No mirrored account can reproduce another's fills exactly. Every replication has lag, and lag has a price that compounds over many trades.

This is why a leader's public history should be read as evidence about their process, never as a prediction of your account's returns.

Past performance is not indicative of future results. Perpetual futures are leveraged instruments and carry a substantial risk of loss, including the loss of your entire position.
