optika

optika is a tool focused on investment risk control, helping you calculate and manage your positions effectively. It supports three models: fixed ratio, pyramid, and Kelly criterion. Simply input your capital and risk appetite, and it will provide a maximum position suggestion for a single stock. You can add, delete, modify, and query your holdings, and it records position snapshots. Line charts and bar charts visually present historical changes. Automatic risk alerts are provided when thresholds are exceeded, and stop-loss and take-profit orders are clearly displayed. The interface uses a dark green color scheme and a clean, card-based layout, making complex risk control decisions easy and manageable.
