Nice bit of code there, implementing the classic signal-counting approach.

Below is my riff on it to add:

* Parameterized filter requirements. Added ParamOptimize( ).

* Put in LongShortBoth logic and N-bar stop for analysis purposes.

* Replaced obsolete (per the docs) "ColumnX =" statements with AddColumn() statements.

* Colored the long signals green, short signals red in the Exploration.

* Added SummaryOrAll switch for Exploration column output.

* Put parameters in front of output.

Pictures of the output, a sample equity curve, and code that can be cut/pasted cleanly have been posted in the CFT Forum at:

Against all odds (draft). Written by Thierry HUITEL o-l---}
based on Jim Varney's work-- CANDLESTOCHASTICS- -
and all the amibroker group :-)

This Exploration is a scan for 24 different buy or sell signals.
The odds are 1 of 6 to get a TWO with a dice. If you try 1000 times, the odds are more than 99%.
The aim of the exploration is to find days when many bullish or bearish signs are triggered at the same time.
If 5 indicators give a buy advice, it is more reliable than one.
I invite everybody to add your own systems to these ones, to improve the reliability.
And experimented technical analysts could give advices to avoid the trap of using several
different indicators all working off the same input data.

Vol Index: this column is the ratio of today's volume to the 14-day average volume.
This column should be sorted Descending. The best signals are occur when VolIndex is at least 2 or higher.

PCL[up]: Piercing Line, "up" signifies Bullish.
MDS[up]: Morning Doji Star
BLE[up]: Bullish Engulfing
HAM[up]: Hammer
BRE[dn]: Bearish Engulfing, "dn" signifies Bearish.
DCC[dn]: Dark Cloud Cover
EDS[dn]: Evening Doji Star
TDREI[up] & [dn]: Tom DeMark's Range Expansion Index
KUP[up] & [dn]: Keltner Bands -DIMITRIS TSOKAKIS

COP[up]: Coppock Curve TJ
SMH[up] & [dn]: smash day pattern. DIMA
CHK[up] & [dn]: Chaikin Money Flow. Thierry Huitel

A "1" in the column signifies TRUE, a "0" indicates no signal.
