Howard,
I'm sitting in your old office in Denver, so thought it might be
appropriate to reply to your suggestion.
Someone else was asking about this just last week. Their
reason was to (perhaps) not be trading the same stocks as someone else
using a similar strategy. There was a fair bit of discussion
on that thread, but I don't think that anything was resolved.
Hopefully, TJ will pick up on this and give us a little edit box where we
could say "skip top n rankings".

I would like this ability. I often find that my rankings correlate
well with future performance except for a very few at the top which do
poorly. It would be nice to be able to rotate into, say, the next
unowned ticker in the ranking range of 4 to 10, rather than in the range
of 1 to 10.

Group,
Is this a feature of interest to more than Al and me? If
so, I will send the idea to TJ's suggestion list.
Al, I have wondered the same thing. But I have not passed
the idea on to TJ because I thought I was the only person
who might use this.
My guess is that adding this ability might not be too hard
since it might be as simple as giving the user the ability
to specify the subscripts in the sorting array which is
currently hinded from users.
I assume that to do Positionscore, AB creates some type of
array that holds the positionscore values for the top
stocks. So all users need would be a handle to specify the
array subscript of the stocks they want.
For example, the positionscore array is something like:
Array[1] = IBM, 237
Array[2] = RUZ, 203
Array[3] = MWX, 201
Array[4] = AXE, 176
Array[5] = BEE, 157
The following could tell AB to ignore the top 2 stocks:
MyNewBuyCondition = PositionScoreSubscript > 2;
