A help with a code

Hello there:



I wrote a code in order to use a particular ticker at a particular price, with a particular number of shares, this code send a limit order together with a take profit order, and also fetches the data so that if the stocks goes bellow my risk level , a market order is sent in order to cut loses, this is the code:



def initialize(context):

    context.flag = False

    context.flag1 = False 

    context.ticker = str(input("Enter the ticker:"))

    context.shares = int(input("Enter the number of shares:"))

    context.price = float (input("Enter price:"))

    context.security = superSymbol(secType='STK', symbol=context.ticker , currency='USD', exchange='SMART')  



def handle_data(context, data):

    position = get_position(context.security) 

    if (context.flag1==False and position.amount == 0):

       place_order_with_takeprofit(context.security, context.shares, takeProfitPrice = 1.04context.price, style = LimitOrder(limit_price=context.price))

       context.flag1 = True



    position = get_position(context.security)  

    

    print ('Stock:',position.amount, '; Entry:',position.cost_basis,', Last:',data.current(context.security,'price'))

    if (context.flag==False and position.amount != 0):

        if data.current(context.security,'price') <= 0.965(position.price):

            

            order(context.security,-1*position.amount , style=MarketOrder(), outsideRth=True)

            context.flag = True

        

        

        end        



Now, I get an error message that says "errorCode:110 errorId:851 errorMessage=The price does not conform to the minimum price variation for this contract."



I tried to trade 500 shares of ticker PIX at the enter price of "3.29". Could anyone help me  with this??

Hi Ghery,



It seems like "3.29" is not a valid price for PIX. The price does not confirm the minimum price variation of the contract. What it means is every contract has the smallest price moment for a contract, for example, if the minimum price variation of the PIX is 0.05 you can only place an order that is LTP + (x * 0.05) or LTP - (x * 0.05). 



To put it more simple if the LTP of PIX is 3.05 then the following are the valid prices for PIX



…

2.95

3.00

3.05 - LTP

3.10

3.15

…



You can not place an order at 3.06.



I recommend you check the last traded prices of PIX and from that, you can figure out the minimum price variation for PIX. And from that, you can get a valid price for the same.



I hope this helps

Thanks
