One way is to create two indicators, each of the same moving average.
Something like
nn := Input("Moving average length",1,9999,20);
xx := Mov(C,nn,S);
Now you need to know if this is going up or down, so add
yy := xx-Ref(xx,-1);
And only plot it when it is going up, so
xx*(yy>0);
This is one part of it, which you can make green. The other part is
the same, just change the last line to
xx*(yy<=0)
and plot it in red. Now you have two plots of the same moving
average. A bit messy, but will do the trick. In this case, the
indicator drops to zero when you don't want to follow it anymore. You
could also let it drop to the most recent value e.g. when it was still
used, something like
xx*(yy>0)+valuewhen(1,yy>0,c)*(yy<=0)
will do the trick for the rising and
xx*(yy<=0)+valuewhen(1,yy<=0,c)*(yy>0)
for the falling
