Imran --
You may not get the results you are expecting with Dieter's code.
You asked to sell "when x crossed 'y and z' to the negative
(downside)". Dieter gave you cross(y,x) which doesn't address
the 'z' in your request.
You might try:
Sell = cross(y,x) AND cross(z,x);
But you will most probably find that this is not what you intended
either, because a 'cross' only happens on a single bar and it is
highly unlikely that cross(y,x) and cross(z,x) will occur on the same
bar. Instead, you might use (depending on your intent):
Sell = x<y AND x<z;
or
Sell = x<y OR x<z;
Then use the ExRem() function to get rid of the exta down arrows on
your price chart.
You may also discover that rather than using:
Buy = cross(x,y);
you may really want:
Buy = x>y AND x>z;
