Basic algo I cannot get to run: I am a Noob

# I cannot figure out what I am doing wrong. All I want is the Algo to buy within set parameters of 6 cents above midprice and 6 cents below midprice. 

#I created the algo below to see if I can get the program to buy when price(current) is equal to midprice and above 2day VWAP. Ideally, in an intraday action, I would like this to buy or sell anytime those parameters are met. Yet every freaking time I try to this, I blow up the algo. I have been trying for over two hours. Any guidance is greatly appreciated.

Hi Joshua, "=" is an assignment operator while "==" is an equality operator. In “if” statement you should use "==" instead. Besides, you need to assign the indicator to a variable in Initialize(), so can refer to its value with "Current.Value". Also, please add " if self.IsWarmingUp: return" to skip the warm-up period as the indicator value in this period is not real indicator value.  The condition "current = Mid" is too strict so you won't get any trades.


Thank you, sir. I will make the changes and try again. I will post the updated code if i get stuck again, unless I murder my computer.
