Create Code (python - Mql5 API) to Place and Close orders

Hi

The objective of this job is to create or fix the next code (Mql5 APY Python) and be able to place orders base on the next conditions:

if:

pre == 0 do nothing

pre == 1 open long

pre == 2 close long

pre == 3 open short

pre == 4 close short

The way to validate the job is to implement the code in a JupyterLab notebook runing in a vps with windows and see the results when changing the pre values

In the next link you can find and copy the entire code: https://controlc.com/63fc1b87

On the next lines the code that I been working on but has an error and do not close the the orders, it open the order but it do not close them.... 

####### Order info symbol = "EURUSD" lot = 0.4 deviation = 20 ###### Clasification Model Predictions pre = 4 pre ##### Order info def send_order(symbol, lot, pre, position_id = None): if pre== 0: pass if pre==1 and position_id == None: request = { "action": mt5.TRADE_ACTION_DEAL, "symbol": symbol, "volume": lot, "type": mt5.ORDER_TYPE_BUY, "deviation": deviation, "magic": 100001, "comment": "EURUSD_5min", "type_time": mt5.ORDER_TIME_GTC, "type_filling": mt5.ORDER_FILLING_IOC} result = mt5.order_send(request) return result if pre==3 and position_id == None: request = { "action": mt5.TRADE_ACTION_DEAL, "symbol": symbol, "volume": lot, "type": mt5.ORDER_TYPE_SELL, "deviation": deviation, "magic": 100001, "comment": "EURUSD_5min", "type_time": mt5.ORDER_TIME_GTC, "type_filling": mt5.ORDER_FILLING_IOC} result = mt5.order_send(request) return result ############ Close Trades if pre==2 and position_id != None: request = { "position": position_id, "action": mt5.TRADE_ACTION_DEAL, "symbol": symbol, "volume": lot, "type": mt5.ORDER_TYPE_SELL, "deviation": deviation, "magic": 100001, "comment": "EURUSD_5min", "type_time": mt5.ORDER_TIME_GTC, "type_filling": mt5.ORDER_FILLING_IOC} result = mt5.order_send(request) return result if pre==4 and position_id != None: request = { "position": position_id, "action": mt5.TRADE_ACTION_DEAL, "symbol": symbol, "volume": lot, "type": mt5.ORDER_TYPE_BUY, "deviation": deviation, "magic": 100001, "comment": "EURUSD_5min", "type_time": mt5.ORDER_TIME_GTC, "type_filling": mt5.ORDER_FILLING_IOC} result = mt5.order_send(request) return result #### Placion Orders place_order = send_order(symbol, lot , pre) print(place_order) ##### Order Identification if len(mt5.positions_get()) != 0 : df_2 = mt5.positions_get() df_2 = pd.DataFrame(df_2) identifier = df_2.iat[0,7].astype(np.int64) elif len(mt5.positions_get()) == 0: identifier = None print(identifier) ##### Closing Orders close_order = send_order(symbol, lot, pre, position_id = identifier) print(close_order)
