Pro order doubles sales orders

For some reason I can not understand my systemin using the automatic trading account in real time, PRO ORDER doubles, or make 2 purchases. The first purchase is the amount indicating on the code (USD 2000, equivalent to 1030 shares), but I get a second purchase 300 shares. This is the second purchase does not make sense, since in the code not request that a purchase is made for that amount of shares.

Then the system is still running, making purchases as requested, but the remantenente 300 shares is maintained. To test the system in backtest no duplication purchase orders.
