Trig functions

I have an indicator that requires tangent, is there any built in tan(x) function in quantconnect?

 

Thanks

You can use Math.Tan method from the System.Math class.
For other trigonometric functions, please checkout the Math Class (System).

Additionaly, say we want to use a moving average cross over of the tangents of the closing price, we could implement it like this:

private const string Symbol = "SPY";
private ExponentialMovingAverage fast;
private ExponentialMovingAverage slow;

public override void Initialize()
{
/* Setup methods */

AddSecurity(SecurityType.Equity, Symbol, Resolution.Minute);

// create a 15 day exponential moving average
fast = EMA(Symbol, 15, Resolution.Daily,
x => (decimal)Math.Tan((double)x.Price));

// create a 30 day exponential moving average
slow = EMA(Symbol, 30, Resolution.Daily,
x => (decimal)Math.Tan((double)x.Price));
}

public void OnData(TradeBars data)
{
if (!slow.IsReady) return;

const decimal tolerance = 0.00015m;
var holdings = Portfolio[Symbol].Quantity;

if (holdings <= 0 && fast > slow * (1 + tolerance))
{
Log("BUY >> " + Securities[Symbol].Price);
SetHoldings(Symbol, 1.0);
}

if (holdings > 0 && fast < slow)
{
Log("SELL >> " + Securities[Symbol].Price);
Liquidate(Symbol);
}
}
