    undrstanding indicator apply and ok

    If I change an indicator parameter what function triggers onstartup?

    the reason is i created a drop down list for certain parameter to be drawn. It all works ok but my old drawing still exist. If I press f5 it will erase everything except the parmaeters that I want

    Hello,

    Thank you for the post.

    The Initialize and OnStartup method will be called for every indicator when you open up the Indicator configuration window and also when you reload the NinaScript with f5.

    The lifecycle goes: Initialize() -> OnStartUp() -> OnBarUpdate().

    All 'one time' set up must be done in either Initialize() or OnStartUp(). If you could post your properties region as well as the OnStartup() function, and give more details on what you would like to do I can advise further on what should be done.

    I look forward to your reply.
