Python Trading Engine

[icabero0225]

So I am trying to code a python script to assist me with my stock trading. here's my code so far.

def buy():
   datr = float(input("Daily ATR: "))
   dzd = float(input("Demand Zone Distal: "))
   dzp = float(input("Demand Zone Proximal: "))
   szp = float(input("Supply Zone Proximal: "))
   szd = float(input("Supply Zone Distal: "))
   wr = (datr * 0.02)
   sl = (dzd - wr)
   rsk = (dzp - sl)
   rwd = (rsk * 3)
   t1 = (dzp + rwd)
   t2 = szp
   print("Target 1:", t1)
   print("Target 2:", t2)

def intromenu():
   choice = input("1. Buy\n2. Sell\n\nEnter: ")
   if choice == 1:
       buy()
   else:
       exit()

intromenu()

When I run the program, I enter 1, the program exits with no errors. I'm trying to make it so whenever I enter 1, the function buy() executes. Thanks.
