The new calculation has reduced costs and leveraged the number of UDS.

Those who trade Options on the Average One-Day Interbank Deposit Rate Index (IDI) on B3 now have access to a simplified fee structure, which aligns the transaction cost with the risk of each contract. Furthermore, B3 also included a discount for trading strategies via UDS (User Defined Strategy).

The new streamlined model, which went live on June 3, aims to bring greater simplicity in understanding the product’s pricing tiers, besides encouraging the use of the UDS functionality to trade strategies. In the first two weeks of the implementation of the new model, the average number of traded Options on IDI contracts exceeded 880,000, 85% of which were via UDS. Below, we can observe the evolution of daily volumes via outright and via UDS during the period: 

 

The implementation of the model ensures greater efficiency and cost reduction for investors who trade their strategies via UDS, since the fee structure also includes a discount defined by the number of legs of the strategies traded through the UDS functionality.

By reducing costs and simplifying fee calculations, we hope to not only boost trading of Options on IDI, but also provide a more efficient and attractive environment for investors. Furthermore, trading Options on IDI via UDS generates greater transparency in price formation in this market, while also improving the visibility of traded strategies.
