multiple scripts in parallel execution, trading once per script

  Hi everyone, I was tried differents solutions posted in the forum, but none works in this context.

  I have 2 strategy scripts, script 1 running for ticket AAA, and script 2 running for ticket BBB (both in timeframe 1 second).

  I need these scripts running at the same time and with the restriction of only one trading for script, so in this context will have 2 trading as max.

  First try: using the reserved word ONCE but the script never starts.

  script 2 for ticket BBB

  ONCE operationLaunched = 0 if operationLaunched = 0 then buy 10 shares at market SET STOP %LOSS 1 SET TARGET %PROFIT 1 operationLaunched = 1 endif

  1 2 3 4 5 6 7 8

  ONCE operationLaunched = 0   if operationLaunched = 0 then buy 10 shares at market SET STOP %LOSS 1 SET TARGET %PROFIT 1 operationLaunched = 1 endif

  script 1 for ticket AAA

  ONCE operationLaunched = 0 if operationLaunched = 0 then buy 10 shares at market SET STOP %LOSS 1 SET TARGET %PROFIT 1 operationLaunched = 1 endif

  1 2 3 4 5 6 7 8

  ONCE operationLaunched = 0   if operationLaunched = 0 then buy 10 shares at market SET STOP %LOSS 1 SET TARGET %PROFIT 1 operationLaunched = 1 endif

  Second try, using the solution posted by Nicolas (https://www.prorealcode.com/topic/only-open-1-trade/), instead of 10, using 8*60*60 (8h x 60 sec x 60 sec)

  barindex solution

  if barindex-tradeindex >=10 and myCondition then buy 1 contract at market endif

  1 2 3

  if barindex-tradeindex >=10 and myCondition then buy 1 contract at market endif

  But the problem with this approach is that if script 1 launchs the operation first, script 2 never start in the same day.

  I also try to get the Date, and other feasible variables, but with the same result.

  Thanks in advance, for any suggestion.

  Replace line 1 with these lines (sometimes ONCE behaves weirdly):

  IF strategyprofit = 0 AND Not OnMarket THEN operationLaunched = 0 ENDIF

  1 2 3

  IF strategyprofit = 0 AND Not OnMarket THEN    operationLaunched = 0 ENDIF

  Roberto, thanks a lot for the fast answer !

  So, with this implementation I suppose that both scripts may stay on market at the same time, isn’t? Because OnMarket it’s true only in the scope of the script, and not return a global position of other scripts.

  Tonight I will try your solution. Thank you very much !!

  Yes, separate strategies are indipendent of one another. Each one of them doesn’t know about the existance of the others, even if on the same instrument and TF. They can even open positions in different directions.
