Désolé pour le dérangement !

En fait, j’ai trouvé sur le site le code qui va bien pour ce que je veux faire.

// trailing stop
trailingstop = 100
 
//resetting variables when no trades are on market
if not onmarket then
MAXPRICE = 0
MINPRICE = close
priceexit = 0
endif
 
//case SHORT order
if shortonmarket then
MINPRICE = MIN(MINPRICE,close) //saving the MFE (Maximum favorable excursion) of the current trade
if tradeprice(1)-MINPRICE>=trailingstop*pointsize then //if the MFE is higher than the trailingstop then
priceexit = MINPRICE+trailingstop*pointsize //set the exit price at the MFE + trailing stop price level
endif
endif
 
//case LONG order
if longonmarket then
MAXPRICE = MAX(MAXPRICE,close) //saving the MFE of the current trade
if MAXPRICE-tradeprice(1)>=trailingstop*pointsize then //if the MFE is higher than the trailingstop then
priceexit = MAXPRICE-trailingstop*pointsize //set the exit price at the MFE - trailing stop price level
endif
endif
 
//exit on trailing stop price levels
if onmarket and priceexit>0 then
EXITSHORT AT priceexit STOP
SELL AT priceexit STOP
endif

Par contre, j’aimerais bien savoir pourquoi mon code ne fonctionne pas !
