Order Rejection after IB Price Resolution Change

[John833]

I'm running live and use IB as my broker trading FX cash.
My script has been running smoothly and without issues.

However, I have just changed the price resolution in IB from 0.5 tick to high resolution quotes 0.1 ticks
I've checked the box in Options - Data, Quote FX in 1/10 pip

I've started trading today and my first order has been rejected with this error...

Error=OrderRejected Native error='The price does not conform to the minimum price variation for this contract. (110)'

It was for a sell order at a price of 163.143
I am seeing 0.1 tick resolution on the IB platform and 0.1 tick resolution on NT

Any ideas what could be the problem?

Attached is the log

Hello John833,

Please note that you will need to use HalfPip when you trade forex with Interactive Brokers. Please see the IB connection guide below.

13. If you will be trading currencies (forex):

You must set the correct setting for the "Quote currencies (FX) in:" property accessible from within the NinjaTrader Control Center window menu "Tools > Options > Data".
Set the value to HalfPip
