Classical copy-trading platforms — eToro, ZuluTrade, Myfxbook AutoTrade — pay signal providers a fee per copying account or a share of broker spread. The structural problem is that this incentivises providers to maximise account count, which in turn rewards aggressive showmanship over long-run risk-adjusted performance. The provider's worst quarter is a footnote; their best week is a screenshot pinned to the top of the channel.
The hidden risk transfer
When you copy a provider with a 3x larger account than yours, your absolute position size is smaller but your relative drawdown is identical. When the provider survives a 30% drawdown and recovers, you survive a 30% drawdown and recover. When the provider has 30% of their net worth in the strategy and you have 100% of yours, the survival decision is different. Almost no copy-trading platform exposes the provider's relative-risk setting to the copier.
What a healthier substitute looks like
- The router is dumb on purpose. It accepts signals, applies your risk controls, executes at your broker. It does not rank providers or display return percentages.
- Risk controls are on by default and live server-side. The user chooses the signal source; the platform chooses how the order is sized.
- There is no implicit endorsement. The platform's revenue does not depend on which source you pick.
- The audit trail is yours. If a source disappoints, you can reconstruct exactly what happened — entry, slippage, exit, fees — without relying on the platform's UX.
This is not a complete answer. It's a strict subset of the problems classical copy-trading tried to solve, with the controversial parts removed.
