Eccolo:

DEFPARAM CumulateOrders = False
ONCE N  = 10
RangeHH = highest[N](high)
RangeLL = lowest[N](low)
IF Not OnMarket THEN
   IF close CROSSES OVER RangeHH[1] THEN
      BUY 1 Contract at MARKET
   ELSIF close CROSSES UNDER RangeLL[1] THEN
      SELLSHORT 1 Contract at MARKET
   ENDIF
ENDIF
SET STOP   pLOSS   100
SET TARGET pPROFIT 200
graphonprice RangeHH[1] coloured("Blue")
graphonprice RangeLL[1] coloured("Blue")

in realtà non c’è un limite temporale, in quanto prende sempre le ultime 10 candele, quindi si modifica spesso, quindi basta verificare se in una certa cndela ha rotto il BOX della candela precedente.

Scusa, avevo male interpretato la tua richiesta. Eccolo il codice corretto:

DEFPARAM CumulateOrders = False
ONCE HH    = 0
ONCE LL    = 0
ONCE Barre = 0
IF OpenTime >= 080000 AND OpenTime <= 100000 THEN
   IF OpenTime = 080000 THEN
      HH    = high
      LL    = low
   ENDIF
   HH = max(HH,high)
   LL = min(LL,low)
ENDIF
IF Barre > 0 AND Not OnMarket THEN
   IF close CROSSES OVER HH THEN
      BUY 1 Contract at MARKET
   ELSIF close CROSSES UNDER LL THEN
      SELLSHORT 1 Contract at MARKET
   ENDIF
ENDIF
IF OpenTime = 100000 THEN
   Barre = 4
ENDIF
Barre = Barre - 1
SET STOP   pLOSS   100
SET TARGET pPROFIT 200
//graphonprice HH coloured("Blue")
//graphonprice LL coloured("Blue")
//Graph OpenTime >= 080000 AND OpenTime <= 100000
