Hi The ipad app is really super and I depend on it every time I am away from the PC, however drawing trendlines wil alllow me to do put the entry and exits on the charts of my trades and that would be a huge help in monitoring and showing my past performance to my audience. It would allow me to just bring an ipad instead of ipad and laptop and that's a huge advantage.
