KAMA cross strategy

[Trader Thor]

I'm trying to create my first strategy. The ides is to use 2 different KAMA's crossing, but I'm having a problem. I put one KAMA w/ fast set to 2 (red) on my chart and one w/ fast set to 4 (black).

I then tried to create a strategy that would put an up or down arrow when one KAMA crosses the other and play a different sound for each. I keep getting an error message that says: " The name 'Y' does not exist in the C" Code CS0103 Line 47 Column 67.

What am I doing wrong? Thanks.

{
DrawArrowUp("My up arrow" + CurrentBar, true, 0, 5, Color.DarkGreen);
PlaySound(@"C:\Program Files (x86)\NinjaTrader 7\sounds\Alert1.wav");
}
// Condition set 2
if (CrossBelow(KAMA(2, 10, 30), KAMA(4, 10, 30), 1))

Trader Thor,
Thanks for your post.

Can you try to replace your above code with:

protected override void OnBarUpdate()
{
// Condition set 1
if (CrossAbove(KAMA(2, 10, 30), KAMA(4, 10, 30), 1))
{
DrawArrowUp("My up arrow" + CurrentBar, false, 0, Low[0], Color.DarkGreen);
PlaySound("Alert1.wav");
}
// Condition set 2
if (CrossBelow(KAMA(2, 10, 30), KAMA(4, 10, 30), 1))
{
DrawArrowDown("My down arrow" + CurrentBar, false, 0, High[0], Color.Crimson);
PlaySound("Alert4.wav");
}
}

I've changed the path of the sound alert and the prices of your arrows to High[0].

The problem was I needed to select an indicator to attach the arrow to in the "Y" field.

// Condition set 1
if (CrossAbove(KAMA(2, 10, 30), KAMA(4, 10, 30), 1))
{
DrawArrowUp("My up arrow" + CurrentBar, true, 0, KAMA(2, 10, 30)[0] + -10 * TickSize, Color.DarkGreen);
PlaySound(@"C:\Program Files (x86)\NinjaTrader 7\sounds\Alert1.wav");
}
// Condition set 2
if (CrossBelow(KAMA(2, 10, 30), KAMA(4, 10, 30), 1))
{
DrawArrowDown("My down arrow" + CurrentBar, true, 0, KAMA(2, 10, 30)[0] + 10 * TickSize, Color.Crimson);
PlaySound(@"C:\Program Files (x86)\NinjaTrader 7\sounds\Alert4.wav");
