As per Steve's original answer, remove the loop. AmiBroker works on the entire
array at once. Note also that your comment was wrong; false is 0, non zero is
true.
x = MACD();
y = Signal();
Hist = x - y;
z = Hist > Ref(Hist, -1); // z = 1 if True, 0 if False
// To verify
for (bar = 0; bar < BarCount; bar++) {
_TRACE("x =" + x[bar] +" y =" + y[bar] +" Hist =" + Hist[bar]);
}
