I want to check if a moving average is going in a positive or negative direction since the day before. I have tried mov(c,10,e)>ref(mov(c,10,e),-1) and ROC(Mov(C,10,E),1,$)>0. I have tried absolute values with the same success rate. I can see the values plotted on the chart and it seems it would be a simple effort to check one against the last. Also, I have looked through the book and I didn't see mention of a NOT condition. Is there a way to check for: a AND b OR c but NOT d? thanks

Thanks for the code, I am still going through it to learn how to expand on it. This is an excellent start. Thanks again for the reply. :D
