The way I see the numbers I put on the chart is that any chart where price is near that number 142.5, the halfway point between 135 and 150...it holds the same meaning...which could be a lot or nothing depending upon the price action near the number.
What I use is just a set of geometric numbers derived from Ganns division of the circle by 2 and 3 and the further division of those numbers by 2 to obtain halfway and quarter and further divisions of those numbers...depending on what time frame of the chart I'm looking at.
If I'm looking at a monthly time frame...I'd just use the greater number of 135 as the main number with 127.5 and 142.5 being something resembling an "orb of influence"(for lack of a better descriptor) range around 135 on a monthly chart. As the time frame on the chart becomes smaller, like the daily or less, then the numbers devised by further division, such as the 142.5, become more relevant...possibly.
Obviously from Thursday's reaction to a perceived attempt at the top of the range demarcation of 142.5 it was to much at that time to be overcome...remaining firmly in the range 135-142.5.
