1. Drawings on the charts disappear once switched to another time frame or market. 2. Indicators are set to fit into chart by default which means when multiple indicators are plotted on the chart the candles get squashed to the point that the price action can hardly be detected. 3. No way to add fibo levels other than those come with the app. The full-fledged web app is needed for that. 4. Changing the text size on the mobile app also changes it on the web app. You need larger text on the mobile app due to smaller screen but enlarging the text on the mobile app will automatically give you that gigantic text on the web app and vice versa. 5. Current state of your open positions cannot be monitored while you're on the chart. You need to go back and forth between the chart and your account/positions screen.
