I’m afraid that link doesn’t work, that’s a copy of that post:

You can assembly all of your strategies into a bigger file.

“DEFPARAM CumulateOrders = false” will do the hard job!

Of course you may need to name variables in different ways, say, a1s1 or cond1s1 for the first strategy, then a2s1/cond2s1….. a1s2/cond1s2 for the second strategy etc….

You may name a variable StrategyID = 0 when NOT ONMARKET, then set it to any number you want each buy/sell is executed so you know which strategy was triggered.

Example:

DEFPARAM CumulateOrders = False                                 //Only 1 trade at a time
 
IF NOT OnMarket THEN                                            //Make sure you reset this variable to ZERO when not trading
   StrategyID = 0
ENDIF
//-----------------------------------------------------------------------------------------------------------------
IF (StrategyID = 0) OR (StrategyID = 1) THEN					//Strategy 1
   s1.... = ......
   .
   .
ENDIF
//-----------------------------------------------------------------------------------------------------------------
IF (StrategyID = 0) OR (StrategyID = 2) THEN					//Strategy 2
   s2Avg = Average[20](close)
   s2Rsi = Rsi[14]
   .
   .
   .
   //************************************************************************
   //                                 LONG
   //************************************************************************
   IF close CROSSES OVER s2Avg  THEN
      StrategyID = 2
      SET TARGET PPROFIT 20
      SET STOP PLOSS     10
      BUY nLots CONTRACT AT MARKET
   ENDIF
   //************************************************************************
   //                                 SHORT
   //************************************************************************
   IF close CROSSES UNDER s2Avg  THEN
      StrategyID = 2
      SET TARGET PPROFIT 20
      SET STOP PLOSS     10
      SELLSHORT nLots CONTRACT AT MARKET
   ENDIF

IF (StrategyID = 0) OR (StrategyID = 3) THEN					//Strategy 3
   s3.... = ......
