Angel one old API keys As you are aware Angel one has two dashboards for the API old and new. It seems Angel has deleted all old API keys. Anyone still using the old API key will face errors. Please create the new API keys as per their new API dashboard and register your static IP

All Groww users must use Auto-Assign IP button to get IPv6 addresses and register them in Groww. https://groww.in/blog/static-ip-api-trading-setup

A safe strategy for this week Also regulations going live on 1st April means so many broker systems will publish their regulatory changes. This can result in unstability & outage on brokers. Solution: A sensible solution here is to reduce the risk by trading less quantity & taking less exposure. If you use quantity multipliers, then you can reduce the multipliers.

IPv4 Proxy - Timeout issues - Everybody has started using static IPs now, so usage is high - With IPv4 static IPs sourced from external vendors, we see timeout errors five to six times a day, lasting 30 to 60 seconds - When this happens, it puts unnecessary load as requests become queued Solution: - We are changing our system to avoid queueing - We have raised a ticket with our static IPv4 address vendor to investigate the matter, they have given an ETA of 2-3 days - The best solution is to see if your broker can support IPv6 static IP which does not have all of these problems

Bring in your own IP * If any of you want to buy your own static IP and use it in our system for better speed etc., then we can help you get your own IPs. * You need to contact our whatsapp support number (this is only applicable for paid users)

Support temporary change Support for this week will remain whatsapp only. Calls will not be attended due to the large volume of queries.

Angel One Issues AB2001 - Internal error Some users are reporting above error on Angel one. If you are also getting there please contact smart API team. Angel one system seems to be a lot unreliable recently.

MPP Changes (MKT / SL_MKT) If and only if the default aggressive mode is causing price to go out of range & your orders are getting rejected. Change to mode to NORMAL.

Important Updates Deadline: 28-Mar-2026 - You must assign static IP. Broker setup guide is updated with relevant instructions. Post deadline, any account without static IP will not be allowed - Free trial will be restricted to a maximum of 5 accounts (due to limited IPs) Change going live tonight: - MPP will be set to AGGRESSIVE by default for all clients which will auto-convert MARKET to LIMIT orders (to overcome market orders ban on APIs) - You do have an option to change this from menu (Settings -> General)

**AliceBlue issues today** Some Positions are not updating or missing.

Market Orders Ban on API We see some brokers already started banning MARKET orders on API. If you are seeing market orders disables or being rejected. Then follow below one-time process: • You can go to menu (Settings -> General) • Set Market Price Protection (MPP) to AGGRESSIVE • System will then automatically convert your MARKET orders to LIMIT orders

System Upgrade - 17-Mar-2026 (tonight) 1. Fyers to have IPV6 support (New platform: FYERS_API_IPV6) 2. System to auto-update symbol tick size in case they have changed since our last download. This helps in conversion of LIMIT to MARKET order, as we need to round the calculated limit_price using tick size.
