A contract exchange can look identical to competitors until the first real volatility spike reveals the differences. 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. Ask how stale data is detected and what the fallback is. A single broken feed should not move your margin state on its own. Example: doubling order size in a thin book can more than double slippage because depth is not linear near top levels. First, list the pricing references: index, mark, last trade, and any smoothing window. Then locate which reference drives margin checks. Then test degraded mode: what changes when rate limits tighten or when the venue throttles your order flow. Compute liquidation price twice: once including fees and conservative slippage, and once with optimistic assumptions. The gap is your uncertainty budget. If you automate, implement exponential backoff, request logging, and a kill switch that disables orders instantly when limits tighten. Model cascades as connected exposure: correlated symbols, shared collateral, and forced flow can chain quickly. Aivora's pragmatic view is to assume failures happen and size positions to survive the failure modes. 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.
