I do not understand why this code does not work

[julifro]

Hola. Tengo este código que funciona bien:

if (EMA(100)[0] > EMA(250)[0] && EMA(250)[0] > EMA(380)[0])
{
if(Close[0] < Low[1])
{
Draw.Diamond(this, CurrentBar.ToString(), true, 0, High[0] + TickSize*8, Brushes.Blue);
}
}

But if I modify it this way it doesn't work and I don't understand why. Can someone explain it to me? Thanks.

if(Close[0] < Low[1])
{
Draw.Diamond(this, CurrentBar.ToString(), true, 0, High[0] + TickSize*8, Brushes.Blue);
}

before other code shown,insert this line.

if (CurrentBar < 2)return;

Thanks for your reply. The problem was that Ninjascript editor was not compiling correctly. I have reinstalled Ninja and problem solved.
I incorporate your advice into my indicator. Thanks.
