I have basically no experience in C#.. How can I get this to work?

[unpronounceable1700]

protected override void OnBarUpdate()
{
bool macdline = EMA(12)-EMA(26)
bool signalline = EMA(9)*macdline

if (CrossAbove(macdline, signalline, 1))
EnterLong();


}
}
}

Trying to make it so it enters into a long position when MACD line crosses over Signal Line.

Hello unpronounceable1700,

Welcome to the NinjaTrader forums!

Below I am providing a link to a support article with helpful resources on getting started with learning C# and NinjaScript.

For the CrossAbove the current bar and previous bar values are needed so this only works with Series<double> objects.

https://ninjatrader.com/support/helpGuides/nt8/seriest.htm

Save the values to a custom series, and this can be supplied to CrossAbove().

In the scope of the class:
private Series<double> macdLine, signalLine;

In OnStateChange when State is State.DataLoaded:
macdLine = new Series<double>(this);
signalLine = new Series<double>(this);

In OnBarUpdate():
macdLine[0] = EMA(12)[0] - EMA(26)[0];
signalLine[0] = EMA(9)[0] - macdLine[0];

if (CrossAbove(macdLine, signalLine, 1))
