Full ranking

Every figure below is reported by the operator on its own site and is not independently verified. Blank means the operator publishes nothing — we do not fill those gaps with estimates.

How the score is built

A weighted composite of five criteria, each scored 0–10. The weighting deliberately rewards disclosure, because in a market with no audited performance data, what an operator is willing to publish is the most reliable signal available to an outsider.

Transparency30%

Does the operator publish win rate, P&L, volume and user counts — with a stated method behind them?

Trust25%

Custody model. Do private keys stay client-side, can you export them, is the security model documented?

Track20%

Is there a disclosed track record with a sample size large enough to mean something?

Users15%

Is an active user or trader count published?

Docs10%

Are fees stated plainly up front, and is the documentation deep enough to evaluate the strategy?

Because transparency and track record carry half the total weight between them, a bot that publishes nothing is capped at roughly 5.0 no matter how good its technology is. That is intentional, and it is the single biggest driver of the ordering above.
