Quote from sharp10: My question is: if prices go higher and you have MACD (standard: 12,26) keeping bending lower towards the zero line, what do you make of it if anything at all.
MACD measures the difference (the spread) between the two values in the MACD. In your case, the spread between the 12ma and 26ma.
As the difference between the two diminishes (gets smaller), the MACD will migrate towards the Zero line. When the two are equal, the exact value is Zero. When they cross, you get a Zero line cross.
Thus, as MACD bends lower towards zero, it is telling you that the spread between your two MAs is getting ready to cross down.
Similarly, as MACD moves upwards towards zero, your two MAs are getting ready to get a "positive" cross.
This works for any MA combo, so optioncoaches approach of using similar MA pairs on both his price and his MA helps to "align" the signals he is using.
Divergences, ie, price continues to rise while the MACD is bending lower, is telling you that the short MA is still above the long MA (ie, MACD is above zero), BUT that the spread between them is getting smaller, ie, they are getting closer to am MA cross-over.
Anyone who *really* studies MAs knows that a cross isn't always a sell (or buy), but rather an intersection of two cycles. Sometimes the cycles are so strong and you might get a "skim" rather than a cross, which is in fact a rather strong continuation signal. The MACD will show this as a skim of the Zero line.
There's more to this, but perhaps these thoughts will help you observe MACD in a different light.
