Does Ensign allow you to adjust the scaling on your charts? The main problem I have with Sierra and QT is that you cannot set your own scaling. Sierra will allow you to adjust the range to a user defined setting but you have to go back and reset it every time you move out of the range which is a pain. It is very important to me to keep the scaling on my charts constant. Esignal allows you to do this but I track bonds and the euro and dax with IB data and would like to find a API app that would let you do this. edit: tried to delete this but for some reason it wont do it. I downloaded the demo version and found the answer which I should have done in the first place. It does allow scaling and just about everything else it looks like.
