Create Stock Option Margin

Create a stock-option margin-factor record that sets the global (non-client-level) option margin factors for an underlying.

Request parameters

Required: counter_id. Usually provide the bounds of all three factors and un_covered_min.
See the field descriptions for the format, value range, and business meaning of each field.

Business notes

A record typically carries the stock code, the upper and lower bounds of the initial, maintenance, and forced-liquidation margin factors, and the uncovered minimum factor, serving as the default rule for option margin calculations on that underlying.

Risk warning

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

Result

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