My first NT 8 indicator

[laocoon]

Hello,

I've developed quite a few indicators in NT7, but I've never done so in NT8.
I watched the various tutorial videos, but I'd really appreciate if someone could help me getting started by providing a very simple code snippet.
What I'd like to to is the following:

Draw an UpArrow below a bar if it crosses and closes above the 50SMA.
Draw a DownArrow above a bar if it closes and closes below the 50SMA.

Once I have this I'll take it from there.

Thanks a lot for your help!

Hello laocoon,

Below is a link to a forum post with helpful resources on getting started with NinjaScript and C#.

if (CrossAbove(Close, SMA(50), 1))
Draw.ArrowUp(this, "MyUpArrow" + CurrentBar, true, 0, Low[0] - 3 * TickSize, Brushes.Green);

if (CrossBelow(Close, SMA(50), 1))
Draw.ArrowDown(this, "MyDownArrow" + CurrentBar, true, 0, High[0] + 3 * TickSize, Brushes.Red);
