Client Option Margin Factor

Update Client Stock Option Margin

Update a client's stock-option margin-factor record, adjusting the upper and lower option margin bounds for a given underlying.

Request parameters

  • Required: aaid (client), counter_id (stock code).
  • See the field descriptions for the format, value range, and business meaning of each field.

Business notes

The upper (max_*_factor) and lower (min_*_factor) bounds of the initial, maintenance, and forced-liquidation margin factors together define the allowed range of margin for the client's option positions, used in risk calculations.

Risk warning

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

Result

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