Problems with TWS connect(SYMBOL mapping and fractionals size)

[tanas.eduard]

Hi.
Setup new NT 8.0.28.0 64-bit and new TWS Build 10.23.2a, Jun 15, 2023 4:54:18 PM (version from manual)

Have tow problems:
1 - Have warning "Received unknown error/warning: Warning: Your API version does not support fractional share size rules. Please upgrade to a minimum version 163. Trimmed value 98.7 to 98"
2 - When start strategy on multiple symbols from NASDAQ 100 have error "IB was unable to locate instrument. Please verify your symbol mapping is correct for instrument AAPL Nasdaq". This error is stopped strategy and I have it on random symbol. When i open chart in NT with this symbol - all ok. When i try use in strategy sometimes I have error. I would even say so - the error is constantly there, but it migrates between different symbols.

How to fix it?

Logs and traces with screenshots are attached to the message.

Thank you in advance.

Im having the same issue with "...fractional share size rules. Please upgrade to a minimum version 163..."
in contract with support to resolve somehow.. renders my NT8 unusable. can we at least know the cause?

[IsaacBillion]

I see from other threads this problem exist over 3 months already. IBKR is a MAJOR broker.
how come there isn't solution yet???

[NinjaTrader_ChristopherJ]

Our development team is currently doing final testing on version 8.1.2.0 before releasing to the general public.

Again, thank you for your patience.

Hi all,
So had a 2 live sessions with support and we have to wait for 8.1.2.0. Good to hear from Christopher its coming soon.
As a workaround i already have Kinetick data feed and so i have set it as my preferred data provider in the options menu in nt8.
For now it seems to work fine. It is extra cost if you dont already have data subscription though.

Hi,
I have since now, same problem. Massive log messages, 3-4 per second :
07.12.2023 00:15:08 Default Received unknown error/warning: Warnhinweis: Your API version does not support fractional share size rules. Please upgrade to a minimum version 163. Trimmed value 1.92 to 1

I'm using NinjaTrader 8.0.28.0 and IB Gateways and IB TWS both Version 10.23.2a.
Will NT 8.0.28.0 also updated next like the 8.1 version or what can be the solution for that problem?

Regards
Oliver

This issue has been resolve within the current version 8.1.2.1 which can be downloaded using the steps provided at link below. Unfortunately, at this time we do not have any further plans to update the 8.0 platform. The 8.1 platform is the most current version and this version will continue to receive updates going forward.
