I can verify that the problem fykemang is identifying is real and started happening today with Sierra Chart

I can also verify that after talking to IB, there is no change on IB side.

Something has changed on Sierra side regarding symbol format.

In addition to using Sierra Chart, I also use IB Api for other purposes. I can verify that there are ni changes in IB api.

I can also verify that other programs I use with Ib are not having this problem. The problem with symbol format is only in Sierra Chart.
