Thanks. I purchased PowerScan so that I could get some code from
that as a starting place. I actually believe in simple systems to
begin with. One other code I am working on is to buy a stock that
has broken above the 50 day SMA and retested it and held, with the
50 day SMA now in an uptrend on the retest. Sell on a break of the
50 day. Very simple, yet productive. The only way to win the game
is by following the money, and institutions add to positions on
tests of MA's. (The trouble is in making sure you have the first
retest. I'll work on it until I get completely stonewalled before I
ask for help. I'll never learn AFL otherwise.)
I'm sure eventually I will try and develop some indicators to play
with, but for now I only want to do what I know works for me.
Thanks again.
