Hi all.
I was notified by IB that " Due to an external SEC rule update (RIN 3235-AN23), we are required to enforce a change in the round lot sizes of US stock that will vary by price from November 3, 2025. To remove disruption to your trading operations, you must upgrade at a minimum to TWS and TWS API to 10.37 Stable or newer."
Has anyone else received this and what should I do about it?
I’m still on NinjaTrader 8.1.5.2 and like its behaviour.
Would it be safe to upgrade TWS to 10.37 and stay on NinjaTrader 8.1.5.2?
Thanks!
I’m using IB TWS 10.33.1b and have not seen any mandatory update messages.
I’m also on NinjaTrader 8.1.5.2.
In the past, mandatory updates for TWS alerted you with a pop up on login.
Prior NinjaTrader support always seemed eager to make necessary updates to make the transition smooth.
Not sure if this will be the case with the Kraken team.
