For instance, what difference does it make in the diagram of MSFT whether or not the MACD and MACD EMA lines are above or below the 0 divergence line?
Anyone able to help me out on this one?
This is actually two questions, what the MACD has to do with the 0 line and what it has to do with the divergence.
The divergence is simply the distance between the two MACD lines. As that distance narrows, the histogram bars will shorten. As it widens, they will lengthen. This enables you to use the histogram as a momentum indicator (i.e., you can toss out Momentum and Rate of Change). The same dynamic applies to the ADX and DMI, i.e., the ADX represents the distance between DM+ and DM-.
As for the 0 line, conservative traders will often wait for at least one line to cross that line. Even more conservative traders will wait for both. However, more aggressive traders will argue that unless there is a strong trend in place, one is more likely to be trading at or near the end of the move than the beginning, and that one is giving up too much of the move by waiting for all this confirmation (the more conservative would say that without that confirmation, one is just guessing, and if the trend isn't strong, why bother?).
Very aggressive traders will consider a trade at the first uptick in the histogram (if it's under the 0 line, the first downtick if it's above). This will occur even before the lines have crossed each other, much less the 0 line. In this regard, the MACD and histogram can substitute to a large extent for the stochastic and RSI.
So, as with everything else, it all depends on your risk tolerance, how aggressive you are, how comfortable you are with your strategy and tactics, how disciplined you are, etc. as to how you make use of this tool.
