A contract exchange looks simple on the surface, but the plumbing decides who survives volatility. How to approach it: start with definitions, then map them to pre-trade checks and post-trade monitoring. Ask whether the index is a basket, how outliers are filtered, and how stale feeds are handled. A single broken source should not move your margin state. Liquidation paths differ: incremental reductions, auctions, or market orders. The difference is not cosmetic; it changes slippage and tail risk. Treat cross margin as a correlated portfolio. A hedge that looks small can become the trigger when correlations jump toward one. Example: a 0.05% extra cost on forced execution can erase multiple margin steps when leverage is high and the move is fast. Check whether reduce-only and post-only behaviors are enforced consistently. Edge cases often appear during partial fills and rapid cancels. When in doubt, reduce complexity and size, and prioritize venues that publish definitions and failure-mode behavior. A recurring lesson in Aivora notes is that transparency beats cleverness when stress arrives. Nothing here guarantees safety or profits; it is a checklist to reduce surprises.
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.
