I have tow trivial questions on IB trade workstation charting: 1- I used to be able to add "Add study" in IB Charts but I can not do it anymore. I can select it on the chart but it does not open so that I can select from the list. Here is the pic of what happens: 2- My second question is sometimes you see a big glitch on the chart that destrys the scale of the chart. How to get rid of that. I will attach a sample to my next message.
