Draw something with MA slope

[jaragon66]

Hello, sorry about my english I only speak a little bit;
I´m trying to develop a simple indicator that draws something when a MA slope change from falling to rising or rising to falling, I´m using this to draw an arrowup:

if (SMA(10)[0]>SMA(10)[1] && SMA(10)[1]<SMA(10)[2])

DrawArrowUp(CurrentBar.ToString()+"tag1",true,0,Lo w[0],Color.Lime);

But is not working.

Welcome to our forums here jaragon66 - do you see any errors in your NT Control Center log tab when this study is applied?

You likely just miss a CurrentBars check like

if (CurrentBar < 2) return;

at the top of your OnBarUpdate().
