Subject: [amibroker] Formation
efficiency
How many times (expressed in %) a stock gained
more than P% in the next T days after a formation F
?
The answer is in the Exploration
/*FORMATION EFFICIENCY*/
COND=Your condition
here;
T=10;/*Days after the
formation*/
P=10;/*Percentage
gain*/
H1=100*(-<FONT
size=2>1+HHV<FONT
size=2>(C,T)/Ref(C,-T));
Buy=COND;
Sell=Ref(COND,-T);
C1=IIf(<FONT
size=2>H1>P,1,<FONT
size=2>0);
C2=Cum(Sell AND C1);
C3=Cum(Sell);
Filter=1;
NumColumnS=1;
Column0=100*<FONT
size=2>LastValue(C2)/<FONT
size=2>LastValue(C3);
Column0Name="%";
The condition may be a candlestick formation or any
other interesting event (a buy cross), which may be considered as
a "Buy" criterion.
Explore your database
for All Stocks, <FONT
color=#ff0000>n last days n=1
and click on "%" to sort the champions.
A reading 65 in "%" column means that the certain stock in the
65% of F formation gave more than P% gain in T days.
This is a way to backtest a database, when we want to find
the efficiency of a "buy" condition
