LaissezFaire 

Looking at the daily high on the 14th of May using 1-minute, 30 second, 50 tick and 250 volume: ,,, It basically looks the same to me. There might be times where the difference is more obvious of course, but generally, I find that these type of charts end up looking fairly similar.

they key thing is to filter enough noise to see paterns/levels clearer. I use 2m for better illustration 1m would be too much noise.

I use range 6 range 12 all the time
