I am working on the web pages that will describe DDCA SRB and should have them up this week.
Yes, with P&F charts it does lag if the 3 x's or o's are met. I have never used them though.
SRB uses the Slow Stochastic, RSI and Bollinger Bands as the three signal generators. Of the indicators I have studied I like the RSI as the best overall indicator. The Slow Stochastic as well as the PPO or MACD.
You can do the PPO XOver another way:
At stockcharts.com you can set two moving averages. Set one (the top one) to exponential 20 and the other to simple 30. You end up with two Moving averages of nearly the same data except the expo ma is more sensitive to price movements. When the blue line crosses the red line buy and when the blue crosses the red down sell. It's very close to PPO XOver and as a matter of fact I discovered PPO XOver because I thought I could do it that way with PPO and it worked. They do not always give exactly the same signals but are very similar.
