Selling stocks after a certain time

Please refer documentation on scheduled events

You may note/save trade time and then schedule call to self.MarketOrder() after adding required time period.  Above link has sample/example algorithm as well.

Thanks.

Hey Nadeem,

A simple way of accomplishing this is by keeping track of when your entry trade was made with a variable. Then later checking whether the difference between the current time and the entry time has been at least 15 minutes before placing an exit trade. Here's a sample snippet.

class ParticleHorizontalCoil(QCAlgorithm):
     def Initialize(self):

         self.SetStartDate(2019, 10, 1) # Set Start Date
         self.SetCash(100000) # Set Strategy Cash
         self.AddEquity("SPY") # Add our equity

         self.entryTime = self.UtcTime


    def OnData(self, data):

         #If we are not already in a position
         if not self.Portfolio.Invested:
             #Place a market order and save the order time in our variable
             self.entryTime = self.MarketOrder("SPY", 100).Time
        else:
             #If we are in a position and it has been at least 15 minutes
             if (self.UtcTime - self.entryTime) >= timedelta(minutes = 15):
                  self.Liquidate("SPY")
