so once the daily range expands to 31.25% of the median daily range of the last three days would it usually expand to 0.625 of daily median range just like weekly?
20% if price decides to go nowhere.
31% on normal days
46%+ if it is an mbar or the filling out of a cone.
Your line doesn't have to be drawn exactly at these numbers, you just know to draw "something" somewhere when these numbers are reached.
An mbar can be nearly as long as the weekly median but our focus is on reliable minimum targets.
I use two different medians:
a) median of last 3 weeks
b) median of remaining ranges, of the last 6 weeks, after the largest and two smallest ranges are crossed off.
"a" is for weekly targets
"b" is for position sizing & daily targets...
...but feel free to use whichever method you like.
