A consultation with a code

Hello there:



 I am starting  to learn how to use IbridgePy for trading in Interactive Brokers, and I wanted to write a code that actually sends an order to buy 1 share of apple once it gets to a specified price ( to practice).



Neverteless The code that I have, does indeed send a market order to buy 1 share of apple, but the problem is that it sends an order very time apple passes to the specified price, when I just wanted to place the order once…



def initialize(context):

    context.run_once = True

    context.flag = False

    context.security = symbol('AAPL')





def handle_data(context, data):

    print (get_datetime().strftime("%Y-%m-%d %H:%M:%S %Z"))

    print (data.current(context.security,'price'))

    if data.current(context.security,'price')==154.13:

        order(symbol('AAPL'),1 , style=MarketOrder())

        context.flag = True



Could you help me please??

Hi Ghery, 



You can set a threshold to buy a share like if data.current(context.security,'price') > 154.13: . And you can also check count_positions() function from IbridgePy documentation. This function returns the number of shares the account is currently holding. You can use this function to check if you already have a position open and avoid opening another one.
