Wow,
this indicator produces a really good signal. You are a master, MrTools.
Finally got the arrow-function (alerts - true + show arrows - true)
Strange thing, though, once you change symbols the arrows disappear. You got to reopen the indie, close it, arrows re-appear (until: you realize that you have to put the - longer, other - TF-indie on show arrows - false).

How did that happen? Histo below zero, yet blue?
