Hi F,
I don't use it on Dax. I trade two parts on Dax, larger monetary positions taken around the current months options and then futures to balance out. These can be from 5 weeks to 2 weeks. I have done this for many years and prior to that on FTSE which now is so boring and doesn't lend itself to all day scalping.
With the bigger numbers now (last few years) on Dax it does lend itself to great scalping/trading most of the day. So I trade many times in the day. I would best describe (here at least) my methods as pure price action (this is why I get your coalface analogy) as you can see reasonably well from the 1000's of hours experience just watching.
Whilst the EU is in such a flux and swinging wildly as it has for 12 months, I have to pay closer attention to EU as it often trades inversely with Dax. So I get to your thread and am interested to learn more but the time constraints make it hard to do.
I do look at technicals mostly s/r for Dax before the start because so many others trade off it and then the Dax just blows them all out and we look for new ones. I agree with you on 'trickery', not that it is trickery as such but I laugh that people are surprised that there stops etc get taken out time and time again by people who get to make money by doing it. Dax and EU both exhibit these patterns and since following your thread I always keep a 1m EU chart open and trade the swoons etc having cheated a bit and take cognisance of your s/r and made some early notes myself.
Somedays (last 6 months) I could do 100 trades a day, (yes your honour I press those buttons real fast, honest guv), some days 20.
I do believe you would do very well with it and you just need to think of it as another pair.
GL
