140% and 166% are example defaults, not universal bank/broker standards. Replace them with your own contract thresholds.
How this calculator defines the ratio
This tool estimates collateral value divided by loan principal plus accrued unpaid interest. A provider may include supplemental collateral, different valuation rules, or other receivables.
Why regulatory examples cannot be copied blindly
Current Yuanta Securities Finance rules are a public example, while banks, broker collateralized loans, and other stock-pledge contracts may use different thresholds, terms, and cure rules.
