    Shutdown indicator in Market Analyzer when condition meet

    Hi,

    I'm looking to filter over 100 stocks in Market Analyzer with a few existing inbuilt indicators like DailyVolume, LastPrice, etc. I will also add a custom indicator for MCAD and STOC crossover and this indicator will sendmail() when the condition is fulfilled.

    Is there a way to shutdown the indicator from processing after the first email is sent on an instrument? This is to save on computing resource. Then the next trading day, we repeat the process.

    Thanks.

    Hello unjha,

    Thanks for your post.

    Yes, if you are creating a custom indicator you can add logic that would shut off sending e-mail after sending once and then use the FirstBarOfSession as a way to rearm the condition for the next trading session.

    in the OnBarupdate section:

    if (Bars.FirstBarOfSession)
    {
    emailonce = true; // reset for new session
    }

    if (your conditions && emailonce)
    {
    sendmail( ....);
    emailonce = false; // after 1st e-mail send no more until next session.
    }

      Hi Paul,

      This is exactly what I had planned to use.

      My question is: after this condition,

      if (your conditions && emailonce)
      {
      sendmail( ....);
      emailonce = false; // after 1st e-mail send no more until next session.
      }

      will the indicator shutdown processing completely or does it still keep checking for
      if (your conditions && emailonce) on each OnBarupdate?

      I'm looking for efficient ways to lower the use of computing resources.

      Thank you.

        Hello,

        Thanks for your reply.

        The indicator will continue to process on each OnBarUpdate.

        A very very small improvement is:

        if (Bars.FirstBarOfSession)
        {
        emailonce = true; // reset for new session
        }

        if (!emailonce) return; // skip further processing unless emailonce is true

        if (your conditions && emailonce)
        {
        sendmail( ....);
        emailonce = false; // after 1st e-mail send no more until next session.

        }
