MDA - Market Direction Analysis

[augieboo]

Tom, I was just playing around with Excel re your idea and I have a couple more questions. You said:

The ROC for each period would need to be divided by the number of days in the period (this is so longer periods don't dominate the composite).

It seems that doing this will bias the entire index very heavily toward the short side, since, for example, only the 60 period sub-index will only have 1/12th of the weight of the 5 period sub-index.

Is this what you are aiming for?

Is this how NDR does it?

TIA,
