I am trying to implement a simple algorithm that buys/sells a random security based on a coin flip (aka Cramer's algorithm). How can I select a stock at random? The following code does not work, and errors out saying sid takes only one parameter.
import random # Put any initialization logic here. The context object will be passed to # the other methods in your algorithm. def initialize(context): pass # Will be called on every trade event for the securities you specify. def handle_data(context, data): # Implement your algorithm logic here. # data[sid(X)] holds the trade event data for that security. # data.portfolio holds the current portfolio state. # Place orders with the order(SID, amount) method. thestock = int(random.randint(1,200)) stock = sid(thestock) coin = random.random() if (coin < 0.5): order(stock, 1) else: order(stock, -1)
