I want to start daytrading. I need to choose a broker, a data feed (with Level II), and a charting service. I am looking for very reliable service with excellent charts and plenty of technical indicators. I notice that a lot of you go the ala carte approach, choosing a seperate company for each service. For example the following combination seems to be popular: Interactive Brokers for your broker eSignal for your data feed Ensign for your charting Would this be a reasonable combination of services for a beginner? Also why is Ensign needed? Are the charts that come with eSignal inferior? Thanks.
