8ball.niavash ebpour: how can we make this indicator show arrows when it alerts on current bar ? 

  1. “We” are not going to make anything, you are.

    You haven't stated a problem, you stated a want. Show us your attempt (using the CODE button) and state the nature of your difficulty.

    Or pay someone. Top of every page is the link Freelance.

    We're not going to code it for you (although it could happen if you are lucky or the problem is interesting).

  2. Add one or two arrow buffer(s). Where you call doAlert, set the arrow.
