Here's a screen shot of a refined MACD signal line using 60 minute bars.
On the top price chart the 8 and 16 MAs and the parabolics are displayed.
We know the 7/14 EMAs work best for the Qs, but this is GE and the default 8/16s work better here. It's important to identify the "pulse" for each stock or ETF that you trade, which can be a time consuming endeavor and which is one big reason why I trade only a limited basket of stocks/ETFs that I've carefully studied and backtested.
The mid panel contains:
MACD histogram with classic 12,26,9 settings.
And SMAs of 3 and 7
Note how SMAs crosses of the MACDs have produced nice trend trade triggers and kept you on the right side of the market when a smaller time frame view would have kicked you out.
An important screen to monitor on an hourly basis in conjunction with the NYAD if only to track on-going daily momentum.
