I coded MArayP5 indicator per quantismo request (here () as the idea was interesting and made this thread as Big Mike suggested.
So the indi works in any price panel and with any indicator that have plot like SMA, VWAP, TRIX etc.. It draws the ray off from two most recent price values. Look at the picture for examples and settings.
What do you think? Please share more ideas and examples how it could be used. :)
