FMZ meluncurkan Python Local Backtest Engine

FMZ telah meluncurkan Python Local Backtest Engine

Paket python mesin backtest FMZ mendukung python2 dan python3; mendukung sistem Windows, Linux, Mac OS.

Menginstal

Masukkan perintah berikut di baris perintah:

pip install https://github.com/fmzquant/backtest_python/archive/master.zip

• Catatan: Saat menginstal mesin di sistem Mac OS, jika ada pembatasan keamanan, Anda perlu menambahkan sudo di depan pip, dan kata sandi sistem akan diminta sebelum seluruh perintah instalasi dijalankan.

Contoh Sederhana

'''backtest
start: 2018-02-19 00:00:00
end: 2018-03-22 12:00:00
period: 15m
exchanges: [{"eid":"OKEX","currency":"LTC_BTC","balance":3,"stocks":0}]
'''
from fmz import *
task = VCtx(__doc__) # initialize backtest engine from __doc__
print exchange.GetAccount()
print exchange.GetTicker()
print task.Join() # print backtest result

String config dapat dihasilkan secara otomatis dengan menyimpan konfigurasi backtest di halaman Strategy Edit.

Catatan sederhana dari kode Python:

'''backtest
start: 2018-02-19 00:00:00
end: 2018-03-22 12:00:00
period: 15m
exchanges: [{"eid":"OKEX","currency":"LTC_BTC","balance":3,"stocks":0}]
'''
from fmz import *           # Call the FMZ Quant library 
task = VCtx(__doc__)        # Initialize the backtest engine from __doc__ by calling VCtx
print exchange.GetAccount() # Test GetAccount function, and print the account information of the backtested platform 
print exchange.GetTicker()  # Test GetTicker function, and print the market quote information of backtest system 
print task.Join()           # Call the initialized task object, and print the backtest result    

• _doc__

  With two underscores, "__doc__" is used to access the first unassigned string in modules like class declaration or function declaration; the string can be enclosed by """ ""","" "" or ' ', which is to pass the backtest configuration information of '''backtest ... ''' in the code into the VCtx class constructor to construct objects.
