Hi , I am trying to learn hoe to code a programme and I am having some issues. I would like to try optimization , but I am not sure where to put my variable for a stop.

My variable is called “stop” ,

// Definition of code parameters 
DEFPARAM CumulateOrders = False // Cumulating positions deactivated 

// Conditions to enter long positions 
indicator1 = MACDline[12,26,9](close) 
indicator2 = ExponentialAverage[9](indicator1) 
c1 = (indicator1 CROSSES OVER indicator2) 

IF c1 THEN
BUY 1 PERPOINT AT MARKET 
ENDIF 

// Conditions to exit long positions 
indicator3 = MACDline[12,26,9](close) 
indicator4 = ExponentialAverage[9](indicator3) 
c2 = (indicator3 CROSSES UNDER indicator4)
 
IF c2 THEN 
SELL AT MARKET 
ENDIF 

// Conditions to enter short positions 
indicator5 = MACDline[12,26,9](close) 
indicator6 = ExponentialAverage[9](indicator5) 
c3 = (indicator5 CROSSES UNDER indicator6) 

IF c3 THEN 
SELLSHORT 1 PERPOINT AT MARKET 
ENDIF 

// Conditions to exit short positions 
indicator7 = MACDline[12,26,9](close) 
indicator8 = ExponentialAverage[9](indicator7) 
c4 = (indicator7 CROSSES UNDER indicator8) 

IF c4 THEN 
EXITSHORT AT MARKET 
ENDIF 

// Stops and targets 
SET stop pLOSS 30

 

I have tried replacing the 30 with [stop] but it does not work. Any help really appreciated for a newbie.
