Delete Stock Option Margin

Delete a stock-option margin-factor record, removing the global option margin factor configuration for an underlying.

Request parameters

Required: counter_ids (underlyings whose global option margin configuration should be deleted; at least 1 item; {type}/{market}/{code} format such as ST/US/AAPL; use the counter_id of rows returned by POST /v1/datasets/risk_option_margin_ratio_configs).
Optional: audit_frontend_resource (audit context submitted by the caller).
Example: {"counter_ids":["ST/US/AAPL"]}.
See the field descriptions for the format, value range, and business meaning of each field.

Business notes

Once deleted, this global option margin rule no longer applies to the underlying, which falls back to the system default calculation.

Risk warning

This operation deletes a global stock-option margin configuration and affects margin calculations for all client option positions on the matched underlying. Confirm the target record before calling.

Result

On success, the record is deleted; subsequent state and returned data follow the 200 response definition.
