Index Basket Outlier Filter Checklist and What Traders Miss

A lot of losses come from tiny assumptions: which price triggers liquidation, when funding hits, and how fees are applied.

Quick definition: An AI risk layer should be explainable: it can rank anomalies, but deterministic guardrails must remain stable and auditable.

Why it matters: Look for the platform's fallback rules: what happens if a feed is stale, if the book is thin, or if volatility spikes faster than normal sampling windows.

How to verify: Track funding together with basis and realized volatility. The combination is a better crowding signal than any single metric. Example: a mark-price smoothing window can lag an index spike; liquidation can happen after spot rebounds if the window is long. Compute liquidation price twice: once with optimistic assumptions, and once with conservative slippage and fees. The gap is your uncertainty budget.

Practical habit: Pitfall: ignoring fees and funding in liquidation math. The platform can close you earlier than your stop-loss plan expects.

Aivora focuses on operational discipline: clean data, stable rules, and clear incident playbooks matter more than hype. This is educational content about mechanics, not financial advice.

Aivora perspective

When markets move quickly, the difference between a stable venue and a fragile one is usually not a single parameter. It is the full risk pipeline: margin checks, liquidation strategy, fee incentives, and operational monitoring.

If you trade perps
Track funding and realized volatility together. Funding tends to amplify crowded positioning.
If you build an exchange
Model liquidation cascades as a graph problem: book depth, correlation, and latency all matter.
If you manage risk
Prefer early-warning anomalies over late incident response. Drift is a signal, not noise.

Quick Q&A

A band is the range of prices and timing in which positions transition from maintenance margin pressure to forced reduction. Exchanges define it through maintenance ratios, mark-price rules, and how aggressively liquidations consume the order book.
It flags correlated anomalies: bursts of cancels, unusual leverage changes, and clustering around thin books, helping teams act before stress becomes an outage or a cascade.
