public class MyFirstAlgorithm : QCAlgorithm, IAlgorithm {
	public override void Initialize() {
		SetStartDate(2011, 01, 01);
		SetEndDate(2012, 12, 31);
		SetCash(100000);
	}
	//Data event - Every minute, second or tick
	public override function OnTradeBar(data) {
		//Your strategy here!
	}
}

Event Driven Strategies

Designing an algorithm couldn't be easier. With only 2 required functions we take care of everything else! You just Initialize() and then handle the data-events you requested. You can create new indicators, classes, folders and files.

We are committed to giving you the best possible algorithm design experience.

Built for Speed

Just as highways revolutionized travel, we are providing infrastructure to enable rapid strategy design and testing at speeds you've never seen before.

5-10 year second or tick data strategies, across gigabytes of data complete in 30-60 seconds. Roughly 50x faster than possible on your home computer.

You don't need to wait for your simulation to complete! Keep coding and it will notify you when completed.

Leverage your Potential

With your permission we'll introduce you to capital providers to fund your strategy with millions in trading capital. Leverage your potential and earn a great return from your ideas.

First and foremost, your ideas are your property and yours to do with as you like. If you'd prefer to remain independent we'll happily help you execute through your broker of choice.

We carefully selected our investors and partners to avoid conflicts of interest. Our interests are aligned with yours, so lets create the next revolution in finance.

Professional Quality, Open Data Library

Design strategies with a multi-terabyte financial data library, spanning global markets, worth over $100,000 at your disposal.

//Add Security Function Pattern - Request asset data.
AddSecurity(SecurityType marketType,
	    string symbol,
	    Resolution resolution = Resolution.Minute,
	    bool fillDataForward = true,
	    int leverage = 0,
	    bool includePremarketData = false);

//For example - requesting market data:
AddSecurity(SecurityType.Equity, "IBM", Resolution.Second);
AddSecurity(SecurityType.Forex, "EURUSD", Resolution.Minute);

//Requesting Sentiment Data to go with your stock:
AddSentimentData(SentimentType.Estimize, "IBM");
//And Twitter Sentiment with your Currencies:
AddSentimentData(SentimentType.StockPulse, "EURUSD");

StockPulse provides Twitter Sentiment Analysis to identify moods, rumors, and market-moving trends and provides valuable trading ideas and signals on every traded asset in the world.
