How does a Python wrapper simplify the process of coding an algo?
Python is one of many programming languages used by algo traders to create a trading strategy. A Python wrapper simplifies a function into a much shorter expression that can be used repeatedly. When programming a trading strategy, one may need to use the same function or series of functions repeatedly, for example to authenticate login credentials, to pull live data, or to place a trade.
Fxcmpy can easily be installed using pip. Once installed, the user will need to obtain an API token for authentication.Once obtained, connection to the REST API can be established in a single line of code:
con = fxcmpy.fxcmpy(config_file='fxcm.cfg', sever='demo')
Once connected, one can begin using the fxcmpy Python wrapper to pull historical and live prices, set entry orders, execute trades and more. Historical data can be pulled in the periods 'm1', 'm5', 'm15', 'm30', 'H1', 'H2', 'H3', 'H4', 'H6', 'H8′,'D1', 'W1' or 'M1' using a single line of code. For example, entering the following line of code will output the high, low, open and close price of the EUR/USD for the past 30 one-minute candles.
data = con.get_candles('EUR/USD', period = 'm1', number = 30)To create a basic market order, you will provide the instrument and the size of the order (in micro lots) as parameters to either the create_market_sell_order() or create_market_buy_order() methods:
con.create_market_buy_order('USD/JPY', 10)These are just some of the commands available for use.
