Plot(x,"",1,8);// fast trend detector, BLACK
Plot(xA,"",7,8);// slow trend detector, YELLOW
x1=DEMA(StochD(40),t1);// the variable trend detector, GREEN-RED
The last line is GREEN for bullish trends and RED for bearish trends.
Buy/sell signals need more requirements.
Green/Red bars at 50 gives the start and the end of the fast uptrend.
Note that colours may change in your graph according to your
preferences selection. In my colour pallete, 1 is black, 4 is red, 5
is green and 7 is yellow.
