Does work if you trade aligned with major trend and place orders within supp/resist. Tried it with cable on the way up and it works but does require a reasonable sized s/l.
Squeezes in cable subsequent to new highs being made - provide oppurtunities for orders to open to get hit and get in at decent levels.
Found it adds a level of discipline - and requires patience and confidence to know if order doesn't get hit another retracement / reversal will be along like the proverbial bus.
