Not combine per se... Let me explain you buy an example suppose a stock gives a signal under 315 than i track it till quadra gives a follow up signal... Most of the time the signal is followed after 2 to 4 bars... Now u can argue that most of the move has already passed as 315 gave an early signal but this is what u need to pay to avoid wrong signals.... As i already quoted 315 sometimes gives multiple signal before a correct trend is cought... This is where quadra helps me.... If a follow up signal is not received than as per my observation signal of 315 does not sustains.... And if a follow up signal is received via quadra than its most likely that trend will continue with strength... All said and done it suits me hence i use it.... I would advise you to first track this setup than make an opinion for yourself....
