Eccolo (l’ho provato sul DAX, H1, 200K unità):

DEFPARAM CumulateOrders = false
//
body         = close-open
abody        = abs(body)
if range > 0 then
   ratio     = abody / range
else
   ratio     = 0
endif
bodytop      = max(open, close)
bodybottom   = min(open, close)
shadowtop    = high-bodytop
shadowbottom = bodybottom-low
longcandle   = (ratio > 0.6)
//
Hammer       = (body[1]<0 and longcandle[1] and low<low[1]   and shadowbottom>2*abody and shadowtop<0.3*abody)
ShootingStar = (body[1]>0 and longcandle[1] and high>high[1] and shadowtop>2*abody    and shadowbottom<0.3*abody)
//
Ema21        = average[21,1](close)
Ema200       = average[200,1](close)
//
// Condizioni LONG
CondL1       = Ema21 > Ema200
CondL2       = low  <= Ema21
CondL3       = close > Ema21
CondL        = CondL1 AND CondL2 AND CondL3 AND Not LongOnMarket  AND Hammer
//
// Condizioni SHORT
CondS1       = Ema21 < Ema200
CondS2       = high  >= Ema21
CondS3       = close < Ema21
CondS        = CondS1 AND CondS2 AND CondS3 AND Not ShortOnMarket AND ShootingStar
//
IF CondL THEN
   BUY 1 CONTRACT AT MARKET
ELSIF CondS THEN
   SELLSHORT 1 CONTRACT AT MARKET
ENDIF

Non avevo fatto caso al fatto che hai pubblicato nel forum ProScreener, ho solo letto la tua richiesta di una strategia e l’ho creata.

Appena possibile la converto in uno screener.
