Object reference error

[federicoo]

Hello, I'm getting the Error on calling 'OnBarUpdate' method on bar 2453: Object reference not set to an instance of an object, when I run this very simple code, any idea? thanks!

Random rnd = new Random();

protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;

//if(CurrentBar < 50) return;

if (CurrentBars[0] < 10)
return;

// only process real-time OnBarUpdate events
if (State == State.Historical)
return;

if (rnd == null)
return;


R = rnd.Next(1, 10);

// Set 1
if ((R == 1) && (Position.MarketPosition == MarketPosition.Flat))
{
Print(@"COMPRA, R = " + Convert.ToString(R));
EnterLong(Convert.ToInt32(DefaultQuantity), "");
}

// Set 2
if ((R == 2) && (Position.MarketPosition == MarketPosition.Flat))
{
Print(@"VENTA, R = " + Convert.ToString(R));
EnterShort(Convert.ToInt32(DefaultQuantity), "");
}

// Set 3
if ((R != 1)
&& (R != 2))
{
Print(@"R = " + Convert.ToString(R));
}

}

Hello federicoo,

The error you are seeing means an object was null.

I tried the code but don't see what the error may be.

The best way to track down this type of error in a simple code like you provided would be to just comment out the code and then uncomment sections of the code to find which specific part is throwing the error. Once you find the line in question we could review that together if its not apparent what the problem is.


I look forward to being of further assistance.
