BTSE Service Notice

BTSE rolled out the incremental order book “delta” updates in November 2021. The preceding order book API (pre-November 2021) will cease to be supported as of the date and time noted above.

To ensure trading strategies are not affected, all API users are strongly advised to upgrade their trading systems by updating the order book delta API before the effective date. The November 2021 updates were made to provide API users with faster response times and more granular data transmissions.

Thanks for your continuing support!
