The biggest edge is not a secret indicator; it is knowing what the system will do under stress. Testing guide: use small-size experiments to validate edge cases before deploying serious capital. Test marks vs index under fast moves, then test liquidation math with fees and conservative slippage assumptions. Liquidation is a path, not an instant. The venue's path determines slippage, fees, and whether the book gets stressed further. Example: a temporary rate-limit tightening can cause missed exits and worse effective prices even without a price crash. When risk limits are tiered, confirm how tiers are computed and updated. Silent tier changes can invalidate backtests. Then test degraded mode: what changes when rate limits tighten or when the venue throttles your order flow. Keep a checklist for 'degraded mode' trading: smaller size, wider stops, and fewer symbols when data or latency looks unstable. Compute liquidation price twice: once including fees and conservative slippage, and once with optimistic assumptions. The gap is your uncertainty budget. Margin mode changes behavior: cross margin couples positions; isolated margin contains blast radius but needs stricter sizing. Aivora discusses these topics as system behavior: define inputs, test edge cases, and keep controls auditable. Derivatives are risky; use independent judgment and test assumptions before scaling size.
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.
