>From the net the only definition of buy signals referred to for the BPI is
this
Buy signal is given when a column of X's exceeds a previous column of X's.
So I will use this literally and count any stock where the current column is
rising and is higher than the previous rising column. Makes it easy, X marks
the spot.

Subject: [amibroker] Re: Bullish Percent Charts
Graham,
I have had some email difficulties the past couple of days so
forgive me if I overstate something that has probably already been
discussed.
Bullish Percent Index - I will talk about the BPNYSE since that is
the main indicator used by Dorsey Wright.
For every ticker on the NYSE you find out how many stocks are on a
PnF buy signal. Then you take the #buys/total# and this gives you
your value for the day. Each stock has one vote. And if the stock
is on a buy it can not change it's vote until it goes on a sell
signal.
The traditional scale you found is the correct scale. This should
be used before moving to a log scale.
Hopefully my email issues are resolved (and Yahoo is not bouncing
any), so if i can answer any questions please let me know.
Regards,
Peter
