  Interesting, most posts on here are about trying  get/keep scripts going.

  In probacktest code command section there’s ‘QUIT’

  https://www.prorealcode.com/documentation/quit/

  However, for indicator I don’t think there is one.

  Only way would be to force a known error after condition met.

  IF condition THEN

  Highest[-1]

  ENDIF

  This would throw a negative index error. Different ones, LOWEST[-1] could give option if different fail condition need to be set.

  Some of these tricks work beyond indicators.

  However, the only consistency between indicators, backtest and algo’s, is there inconsistency.

  Don’t assume what works in one will work in other, or at least the same. best to check first.

  Hello Manuel,

  Because you said “ProBuilder” people assume you referred to Indicator code.
  But it seems not making sense to “immediately quit” an Indicator. So assumed you meant to refer to Strategy code :

  If you randomly Quit (which indeed is the command for it), Open Positions will be thrown out. Whether this (already) has been activated for PRT-IG I don’t know. But for PRT-IB it sure is. This is so since last June 17.

  Regards,
  Peter

  Hi Peter,
  Actually, in my post, I DO refer to the code of an indicator. Suppose, I open the chart for a certain instrument and it only contains one year of data. In that case, I don’t want to continue running the indicator because I know it will cause an error and then PRP will disconnect the indicator from the chart. A previous test on the number of years would avoid that inconvenience and handle the situation gracefully. In all the languages ​​I know, there is a statement like “quit” or equivalent that immediately suspends the execution of the code and returns control to the operating system. Is there something similar in Probuilder?
  Regards,
  Manuel

  Well, nice … I touch some I think F-key by accident, and the PRC browser screen is replaced by a stupid GitHub screen.

  Hi again, Manuel,

  I don’t feel the lust to type all again (maybe later). But summarized : Use If in the Indicator under which your code is  executed, which If gets false when there’s danger around the corner. Under the Endif Return.

  Sorry …
  Regards,
  Peter

  Edit :

  If NoDangerYet then // Your Indicator code. Endif Return

  1 2 3 4 5 6 7

  If NoDangerYet then     // Your Indicator code.   Endif   Return
