DislikedI have spoken with Daryl previously on his GMMA techniques, he was most interested to hear they were being used in the FX markets successfully (I will get around to that article one day Daryl). The most important thing to come out of my conversations with him in relation to GMMA were compression, expansion and distance between the short term and long term averages. This is explained to some degree in his Trend Trading book which I have read several times and recommend highly to others (although I may be biased to fellow Aussie authors ).
In a nutshell, the very basics of it are quick expansion shows excitement, compression shows agreement on value and price which could signal a trend change and does show the lack of an underlying trend, while if the distance between the short and long term GMMA's remain relatively consistant, then you know the trend is well established and well supported, and can feel a little more confident in jumping on a trend late. Below is today's EUR chart as a demonstration:
It is not of course the Holy Grail, you do get the same formations with two different outcomes, and it takes some interpretation so it is not something that can be programmed in a hard and fast way, but the method does give a nice easy visual way of determining trend status. Hope some of that helps.
