It is a personal view, but I guess the real purpose of technical analysis and a charting software, with your ami's meta's etc is the ability to be able to code your technical analysis strategies, be able to backtest them under various market conditions, run multiple strategies at the same time so you get the power to watch not 1/2 chart but maybe 20 at a time which is humanly not possible. Some of the latest softwares have pattern recognition, and neural networks, which even go to the extent of using Artificial intelligence to predict the winning probability of the next signal...
But there are brilliant traders, who just read the tape, that is just look at a chart, market depth and trigger some fantastic trades..
What I was trying to say was, if the idea is to look at a chart, add a couple of Moving average lines, a RSI, and look at candles, it is probably not financially viable to spend 30k on a software and then pay 4k/month on data feeds.
As I said earlier, that would be like buying a porsche and driving at 60km/hr.
