Hold Closing Price to a Constant Value

[Trader_781]

I am wanting to assign the closing price of a bar to a double variable when certain conditions exist, but I do not want the value to be updated each time the closing price is updated. I want the value to be held constant and used for other calculations in the code. How is the best way to accomplish this?

Hello Trader_781,

Welcome to the NinjaTrader forums!

You could use a bool to only set the value once.

private double myDoubleValue;
private bool doubleSet;

In OnBarUpdate:

if (doubleSet == false /* && other conditions to set value */)
{
myDoubleValue = Close[0];
doubleSet = true;
}

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