To find the B in a trend we start from the lowest low to the next highest high.
as long as the candles DONT pass the A we are still in a trend, and i don't ever recommenced trading against the trend.
*** notice that the C will be found in between the A-B boundary this is 90+ % of the time.. if its not found there its normally due to a fundamental announcement.
** note as well that the D will be Higher (long) then the B and the D will be lower then the B in a Short.
( this swing works on all leaves and time frames the zig zag motion is what the market does)
