Currently, the KRX system is in operation and does not support depositing margin funds directly to the VSDC. Before opening a position, clients must ensure sufficient funds are available in their derivatives trading account at VPS; there is no requirement to deposit margin funds directly to the VSDC.

If a required margin amount arises in the client's derivatives margin account on the trading day (T), VPS will proactively submit the amount needed to the VSDC on the client's behalf by 9:30 AM on T+1, in accordance with VSDC regulations.
