/*
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
RSI[up] & [dn]: Relative Strength Index 14 periods
MFI[up] & [dn]: Money Flow Index
ST2[up] & [dn]: Stochastic Slow - Donald Dalley
DIV[up] & [dn]: % R divergence -DIMITRIS TSOKAKIS
KST[up] & [dn]: MARTIN PRING'S KST MOMENTUM SYSTEM -TJ
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.
