mcTws issue - upgrade tws api to a minimum version 163

Postby Meecc » 24 Apr 2023

I'm using mcV14R6 with ib tws Build 10.20.1d, Nov 29, 2022 4:06:13 PM.

Got the following message and eur.usd cash data stops,

"TWS warning message: Id= 1; code= 10285; description=
Warning: Your API version does not support fractional share size rules. Please upgrade to a minimum version 163."

Please suggest, what is the combination of mc and tws version to solve this issue ?

Hi Meecc,

This message appears due to the IB API changes implemented in TWS build (10.20.1h (Jan 10)).
The latest MultiCharts 14 versions starting from Release 7 are compatible with the latest IB TWS/Gateway versions.
