I've been using esignal for a while now and I have been happy with them and their customer service. However, there software is limited. All I am looking for is streaming software which will enable me to overlay 15-20 different stocks on the same chart. It would be ideal if I could chart the y-axis in terms of percentage instead of just price. looking forward to hearing back from you guys. Feedback would be appreciated as I have not really had much experience with different software.
