Create Client Stock Option Margin

Create a stock-option margin-factor record for a specific client, defining the upper and lower option margin bounds for a given underlying.

Request parameters

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

Business notes

A record typically carries the client, stock code, and the upper and lower bounds of the initial, maintenance, and forced-liquidation margin factors, used in margin calculations for the client's option positions.

Risk warning

This operation adds a client-level stock-option margin configuration and directly affects the margin requirements on the client's option positions. Confirm the target client and parameters before calling.

Result

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