I moved your topic to the english forum, instead of the french one, since you used english.

I don’t know whether Vonasi’s answer in the other post was what you were looking for, but I wrote something while Vonasi was typting and I’m posting it:

FastAvg = average[20,0](close)
SlowAvg = average[100,0](close)
c1 = FastAvg > SlowAvg
c2 = FastAvg CROSSES UNDER SlowAvg
c3 = FastAvg < SlowAvg
c4 = FastAvg CROSSES UNDER SlowAvg

ONCE Treshold = 50 * pipsize
IF Not OnMarket THEN
   MyPrice = 0
   TradeON = 1
ELSIF OnMarket AND MyPrice = 0 THEN
   MyPrice = TRADEPRICE
ENDIF

IF LongOnMarket THEN
   TradeON = 0
   x = close - MyPrice
   IF x > Treshold THEN
      TradeON = 1
      MyPrice = MyPrice + Treshold
   ENDIF
ENDIF
IF c1 AND TradeON THEN
   BUY 1 CONTRACT AT MARKET
ENDIF
IF c2 THEN
   SELL AT MARKET
ENDIF

IF ShortOnMarket THEN
   TradeON = 0
   x = MyPrice - close
   IF x > Treshold THEN
      TradeON = 1
      MyPrice = MyPrice - Treshold
   ENDIF
ENDIF
IF c3 AND TradeON THEN
   SELLSHORT 1 CONTRACT AT MARKET
ENDIF
IF c4 THEN
   EXITSHORT AT MARKET
ENDIF
