Angel One - SENSEX orders blocking We’re seeing that Angel One has started blocking all SENSEX option orders with the error: “token categorized under cautionary listings.” This affects all Angel One API users on all platforms. This is a broker-side restriction from Angel One and not an issue with our app or APIs. Unfortunately, we can’t override it from our end. What you can do: - Please contact Angel One support and ask why SENSEX options are blocked on your account. - Once Angel One removes the restriction, orders will work as usual in our app.

System Downtime - Today @ 10.30 PM onwards We have some emergency changes.

AT Desktop Client - New version Released Please upgrade to the latest version (5.0.0).

IPV6 - Compatibility It is extremely important in immediate future that your broker supports IPv6. Most leading brokers already support it. - Please ask your broker if Static IP for the API can be IPv6? - If they do not support it, please ask to implement this on top priority.

Important Notice: Upcoming Broker System Changes Some brokers are likely to update their systems in the next few weeks. Although, the final deadline is April 2026; the brokers have right to upgrade before it. We are working actively to adapt our platform to these changes. However, because we cannot update all broker integrations simultaneously, we are prioritizing them based on demand. What this means for you: Potential Downtime: If your broker makes an incompatible change, our system may be temporarily unavailable for that specific broker until we release an update. Action Required: We recommend performing a basic check every morning (such as placing a test order or refreshing your portfolio). If you encounter any issues, please report them to us immediately.

Maintenance completed We have done some minor upgrades, please login and verify your accounts. Place some sample orders & view portfolio data. Please report any issues if you notice it.

Auto Split quantity issue fix for December contracts We have decided to implement a change on our side to make sure the freeze limit works for both December & January contracts. It will be deployed this weekend.

Users trading in the December contracts have to manually enter or exit. The TRADE screen has an option to enter manual split quantity. For December contracts use (split quantity): Nifty = 1800 Banknifty = 595
