You show some recent good buys signals in your three website charts. I can’t tell the data period on the charts though.

What I think most people want is clear buy/sell signals without having to do a lot of “pattern recognition” themselves. So I do it for them. I use the up/down volume ratio to amplify the message of the AD line, and I also use only the change in the change (the second derivative) of the resulting metric, then I ignore those that are within one standard deviation of the sample to filter out the noise. After all that, and we have an up or down trend as indicated by the moving average, we get a buy or sell signal.

By the way, its OK to give a URL when related to the subject. In your case, its http://marketfractals.com/.

I experimented using the AD volume also, but it seemed so similar I left it for now. I am not saying it wasn’t worthwhile. I do see some real possibilities in using total volume. For instance, what does it mean when you get increasing advancing volume as total volume is falling off.

There is a lot more to advancing/declining issues and volume.

Thank you.

I was going to do it with your data, but I guess you’ve beaten me to the punch. For what it’s worth, I have found that the AD line all by itself isn’t enough. I combine it with the up/down volume in a second derivative oscillator and and the Exponential Moving Average to derive real time buy/sell signals.

You can check it out during market hours on my website. After hours, you get the same thing but for daily closing price/volume data.
