I can't remember the original sources, but I came across the 34 day EMA a few times in the past. I think Leavitt Brothers might use it to denote a change in long term trend. IE the stock starts trending up when the price crosses above the 34 - and vice versa.
With my current short term trading focus I must say I don't rely on Moving Averages (or most other indicators) for my trading.
I'm still sorting out my intraday approach but I try to keep it pretty simple to determine entry/exit points.
For support/resistance I use Fibonacci and/or Pivot Points.
To that I add the Bollinger and Stochastic and that's about it.
