Thats the 'classic' interpretation of H&S, but we haven't even got a confirmed right shoulder yet, so plenty of time to see how it plays out.
With prorealtime, the end of day version is completely free (what I'm using). That includes programmable screeners, backtesting etc. You can't get better value than that :) They do offer a free trial of the real time version which is of course accompanied by calls from their sales reps. It's good but a bit pricey for me with the monthly software cost and fees for each data feed. I
think IG Market's advanced charting option is basically the same software as well.
