I see, this is the reason why you would have difficulty supporting Asian products. But there are other quote vendors and i am sure they face the same problems supporting IB feed. I see this as an important issue that you would need to resolve for a longer term. Else how can you do testing for these ...

I have also tried, and found the same error as "Guest".

Plotting JGB Options ending with 5 like JGB1325F6 will get this error while others ending with zero like JGB1320F6 will be okay.

Just open up a chart, it will load fine, save workspace and restart Multicharts and you will see the error.
