My real-time charts on Interactivebrokers TWS trading platform have been disappearing on the last 2 versions of TWS (both web and standalone versions). I'm wondering if this is because the chart part of my registry is messed up since I've used 2-3 registry cleaner demos. Can someone tell me where the TWS charts are located in the registry so that I can remove them, and reinstall them. I want to keep my other TWS settings. Another thing I do not understand is why QuoteTracker charts that use IB's data feed come up faster than IB's real-time charts.
