Price Limits: Rapid Fire

What this video covers

• The daily price limit baseline: why it is always measured from the prior session's settlement price, never the open, high, or low
• What reaching a limit actually stops and what it does not stop: prints beyond the boundary versus continued trading at or inside the range
• How a locked market forms from order imbalance, not from the limit rule itself, and which side of the market it traps in locked-limit-up versus locked-limit-down conditions
• Why meeting a margin call does not unlock a locked market, and what that cash infusion actually accomplishes for the account
• The exchange rationale for limit expansion: restoring price discovery, not encouraging volatility, and how margin requirements step up and down in tandem
• The circuit breaker as a separate, market-wide, percentage-based halt with tiered responses, and why only the deepest tier ends the trading day
• The overnight exception for equity-index futures: a percentage cap that keeps the market open rather than triggering a halt
