I'm looking to upgrade my trading software. I have been using DASTrader software for a few years. Overall, I have been very happy with the software. It is updated often and is very seldom down. It has Level 2 quotes and charts just like every day trading software. Its not really a bells and whistles software, so its missing some stuff like backtesting. However, it is very fast on the execution side. You can customize your own hotkeys, which is very helpful. It has a slightly different way of charting the DMI indicator which is great and I use all the time. There's an ESL trading component that can be applied and is very efficient. What are some of the other systems/software that people find effective?
