Post-only Order Edge Cases Framework for AI Contract Trading Exchange

People over-trust dashboards. The best verification still comes from reading the rule path end to end. Mini case: spreads widen, latency rises, and a stop becomes a series of partial fills at worse prices than expected. Fee design shapes behavior. Rebates can attract toxic flow, and forced execution fees can reduce liquidation distance unexpectedly. Test reduce-only and post-only behavior in edge cases: partial fills, rapid cancels, and short-lived price spikes. Example: a 0.05% extra cost on forced execution can erase multiple margin steps when leverage is high and moves are fast. The fix is usually not more leverage. It is smaller size, clearer triggers, and verified liquidation paths. Latency risk is real. When latency rises, a maker strategy can become taker flow and your costs jump right when you need stability. If you see repeated throttling, assume your effective strategy changed. Re-run your risk math with higher costs and worse fills. When in doubt, reduce complexity and size, and prioritize venues that publish definitions and failure-mode behavior. Aivora frames risk as a pipeline: inputs -> checks -> liquidation path -> post-incident logs. Build around that pipeline. 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.
