Provides simplified, multithreaded, socket-based Python interfaces to MT5 gateways. PyMT5 requires a [DevCartel MT5 gateway](https://github.com/devcartel/devcartelgateway64) installed on the MT5 platform to work with PyMT5.

## Installation
PyMT5 supports both Python 2 and 3. Simply install from [PyPI](https://pypi.org/project/pymt5) using `pip`:

pip install pymt5

## Example
```python
import pymt5

def onData(data):
    client = data.get('client_id')
    # Login
    if data.get('type') == '1':
        # Send heartbeat
        m.send(client, {'ver':'3','type':'6'})
        # Send login OK response
        m.send(client, {'ver':'3',
                        'type':'1',
                        'login':data.get('login'),
                        'password':data.get('password'),
                        'res':'0'})

m = pymt5.PyMT5()
m.onConnected = onConnected
m.onDisconnected = onDisconnected
m.onData = onData

```

## API
__pymt5.PyMT5([_host=''_], [_port=16838_])__  
_host: str_  
_port: int_  
_➥return: object_  
Starts a PyMT5 server and listening on a port defined by _port_.

>> m = pymt5.PyMT5()

Upon incoming connection from a gateway, PyMT5 stores client information in `pymt5.requests` in dict format as

__pymt5.stop()__  
Disconnects all MT5 gateway connections and stop the server.

>> m.stop()

__pymt5.broadcast(_data_)__  
_data: dict_  
Sends a message to all connected gateways. Consider using this when sending market data.

>> #send a tick
    >> m.broadcast({'ver':'3','type':'4','symbol':'EURUSD.TEST','bank':'dc','bid':'1.2661','ask':'1.2665','last':'1.2665','volume':'1','datetime':'0'})

__pymt5.send(client_id, _data_)__ 
client_id: int 
_data: dict_ 
Sends a message to a connected gateway.

>> #send heartbeat
    >> m.send(123145536110592, {'ver':'3','type':'6'})

__pymt5.disconnect(client_id)__ 
client_id: int 
Terminates a connection.

>> m.disconnect(123145536110592)

__pymt5.onConnected(client_info)__ 
client_info: dict 
A callback `onConnected`, if assigned, is called upon a successful connection from a client. Client information can be accessed from `client_info`'s values as `client_id`, `client_address` and `client_port`.

>> def onConnected(client_info):
    >>     print(str(client_info))
    >>     # print {'client_port': 64941, 'client_address': '127.0.0.1', 'client_id': 123145536110592}
    >>
    >> m = pymt5.PyMT5()
    >> m.onConnected = onConnected

__pymt5.onDisconnected(client_info)__ 
client_info: dict 
A callback `onDisconnected`, if assigned, is called upon a disconnection from a client. Client information can be accessed from `client_info`'s values as `client_id`, `client_address` and `client_port`.

>> def onDisonnected(client_info):
    >>     print(str(client_info))
    >>
    >> m = pymt5.PyMT5()
    >> m.onDisconnected = onDisconnected

__pymt5.onData(_data_)__  
_data: dict_  
A callback `onData`, if assigned, is called upon receiving messages from gateways. See [Data Format](#data-format) for more information.

>> def onData(data):
    >>     print(json.dumps(data))
    >>
    >> m = pymt5.PyMT5()
    >> m.onData = onData

## Data Format
Data is to be composed as a dict with key/value defined below to be sent and received from a gateway.
