Event Driven Strategies

Event Driven Strategies

Designing an algorithm couldn't be easier. There are only two required functions and we take care of everything else! You just Initialize() your strategy and handle the data-events you requested.

You can create new indicators, classes, folders and files with a web based full Python and C# compiler with auto-complete and debugging. We are committed to giving you the best possible algorithm design experience.

class MyFirstAlgorithm(QCAlgorithm):
	def Initialize(self):
		self.SetStartDate(1998, 1, 1)
		self.SetEndDate(2020, 07, 12)
		self.AddEquity("SPY", Resolution.Minute)
	//Data event - Every minute, second or tick
	def OnData(self, data):
		//Your strategy here!
		if not self.Portfolio.Invested:
            		self.SetHoldings("SPY", 1)
