Hi Dick, try this snippet. Insted of C (ie. the close price) you
can also set the "basis" below to a moving average (f.e. EMA)..:
/*
PERF3.AFL
Displays performance in % of
the last 1, 5, and 30 days (or bars)
Written by anty3de on Oct 14, 2002
Usage: load into AA and press EXPLORE
*/
basis = C; // ema(C, 9);
perf1 = basis / Ref(basis, -1) * 100 - 100;
perf5 = basis / Ref(basis, -5) * 100 - 100;
perf30 = basis / Ref(basis, -30) * 100 - 100;
AddColumn(perf1, "perf1%", 1.2);
AddColumn(perf5, "perf5%", 1.2);
AddColumn(perf30, "perf30%", 1.2);
Filter = 1; // dummy

Subject: [amibroker] Performance
I'm wondering if anyone out there has developed a performance type
Scan or Exploration that will go through the database (mine is of
6600 stocks) and calculate their % movement up or down on a 1 day -
5day and 30 day basis. Results would appear in colums " 1-day, 5-day,
and 30-day. If so would appreciate the code for such a program.
Thanks.
R.E.(Dick) Hoierman
