Session Hijack Signals Field Notes on Ai-native Perpetuals Exchange

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

What it is: Write down the exact references used: index price, mark price, and last price. Then confirm which reference drives margin checks and liquidation triggers.

What to check: Liquidation is a path, not a single event. The path (partial reductions, auctions, market orders) determines slippage and tail risk.

How to test it: Prefer smaller order slices before changing leverage. Size reductions often cut slippage more than a leverage tweak. Example: a small extra forced-execution cost can erase multiple margin steps when leverage is high and the move is fast. Compute liquidation price twice: once with optimistic assumptions, and once with conservative slippage and fees. The gap is your uncertainty budget.

Common pitfalls: Pitfall: overusing cross margin without correlation thinking. Portfolio coupling can turn a hedge into a trigger.

In Aivora notes, transparency beats cleverness when markets get loud. This note is about system mechanics; outcomes are your responsibility.

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.
