cdcaveman. you can try googling 'amibroker supertrend indicator' but some of the
so called 'supertrend' indicators especially those for MT4 is the Gann HiLo Activator
or variations of it and Not very good at all
attached chart shows 2 common indicators that should be available for Amibroker
the EMA Cross - double blue and yellow lines set to 2 and 3 or any MA cross will do
and the HiLo (Gann) Activator cyan and red line set to 2 which also has arrows
as you can see all 3 indicators have a high correlation between their signals, and
adding an arrow shouldn't be much of a coding problem
but don't be fooled by the arrows, depending on how the price moves, 2 or 3 bars
sometimes need to pass before an arrow appears, and you should be able to see
that on the charts I've posted, the price will have moved Then the arrow appears
and of course sometime an arrow that appears disappears ;
oh and set if possible 'Calculate on Bar Close' to false, at least that's my setting
also included is a 5min CL chart with the same indicators to give you an idea of how
the indicators perform on a small tf - same same
as much as anything the color of the price bar itself indicates the B/S. one thing
about the HLActivator is that you get a sort of Support line, and the idicator is some-
thing of a StopLoss indicator, and that's another method to generate B/S signals
