FMZ ra mắt Python Local Backtest Engine

FMZ đã tung ra Python Local Backtest Engine

FMZ backtest engine python gói hỗ trợ python2 và python3; hỗ trợ hệ thống Windows, Linux, Mac OS.

Cài đặt

Nhập lệnh sau trong dòng lệnh:

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

• Lưu ý: Khi cài đặt công cụ trong hệ điều hành Mac, nếu có các hạn chế bảo mật, bạn cần thêm sudo trước pip, và mật khẩu hệ thống sẽ được yêu cầu trước khi toàn bộ lệnh cài đặt được thực hiện.

Một ví dụ đơn giản

'''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

Dây chuỗi cấu hình có thể được tạo tự động bằng cách lưu cấu hình backtest trong trang Strategy Edit.

Tài liệu

Tài liệu API: (đặc biệt là tài liệu gọi các chức năng như GetAccount trong bản demo)

Nhận xét đơn giản về mã 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.
