Price Band (Order Guardrail)

A validation rule that refuses orders priced too far from the current market — catching fat-fingered limits, stale quotes, and unit errors before they reach the broker. A companion crossing-tolerance check refuses limits that would execute instantly by accident. Bands are cheap insurance against the most expensive class of automation bug.

Backtests are hypothetical, computed by DeployQuant's engine on minute-resolution consolidated US market data (2021-01-04 to 2026-07-17, $10,000 starting capital, no margin, fees and slippage not modeled) and do not guarantee future results.
