Summer Reading: Deemer on Technical Analysis and a TOS Code for His Break Away Momentum Indicator

This summer, I've been reading Walter Deemer's Deemer On Technical Analysis and it has been one of the best technical analysis books that I've read in a really long time.  Mr. Deemer gives his take on using TA for longer term investors and he shy's away from the ultra short term time frames that many modern trading books focus on.  He had a long career as a technical analyst and his book is chock full incredibly interesting and witty observations based on his own experiences from his career.


Deemer  not only breaks down what he feels is useful about TA, he also does a great job of explaining his beliefs on why the TA that he uses works.  You're not going to see pictures of massive charts with multiple indicators and squiggly lines in this book..he keeps his charts to the bare minimum of what he considers useful tools.  This book will likely be the book that I recommend to people when they ask me for a good book that can help them get started with investing/trading or with TA in genearl.  If you haven't read it yet, pick it up or order it for the kindle/ipad.  It's well worth the read.

As a bonus, I coded his Breakaway Momentum indicator for think or swim.  This indicator uses the NYSE advances and declines that are added together for the trailing 10 days and then a ratio is created of advances to declines.  To be breakaway momentum, the reading has to be above a 1.97.  These readings only happen once every 31 and a half years on average.  That being said, we had three in 2009..a bit of an anomaly and a testament to how oversold the market was after the 2008 meltdown.  For more info and historical recordings of breakaway momentum check out Mr. Deemer's website here.

Here's a chart, note TOS has some data issues with advance decline numbers starting in 2009 and going backwards, however, this indicator works well with recent data and you can still see the 3 breakaway readings in 2009..there are just some holes in the data that don't look pretty.

And here is the code for you thinkorswim fans:

declare lower;

input adv = "$ADVN";
input dec = "$DECN";
input length = 10;

def up = close(adv);
def down = close(dec);

def sumup = sum(up, length);
def sumdn = sum(down, length);

plot ratio = sumup/sumdn;

plot breakaway = 1.97;
