Alpaba Backtrader API - key issue

yanke_zulu

Hello
I am new to Backtrader and API
I have just followed the steps in the following link
I have done
(import backtrader as bt
import alpaca_backtrader_api
import pandas as pd)

but I dont know how to enter API keys with backtrader,
Could you please help me about how to enter API Keys for Alpaca backratder API? how should be the code let say for the following example?

https://pypi.org/project/alpaca-backtrader-api/
ALPACA_API_KEY = <123>
ALPACA_SECRET_KEY = <123>
ALPACA_PAPER = True

Also, should I change the API everyday? is there anyway to enter as my Python environment variable and use it for each strategy?

thanks

This code looks just like the example in the link you provided. You should be able to replace the <123> with the actual key and the secret key.

Did you find your secret key?

yanke_zulu

the linke has the following, is it APCA SECRET KEY or ALPACA
$ export APCA_API_KEY_ID=xxx
$ export APCA_API_SECRET_KEY=yyy

1- I am really confused about the format, if my api key is AAA
and my secrett key is BBB, is the following format is correct?
do i need any " ' " or any "> " in the format

import backtrader as bt
import alpaca_backtrader_api
import pandas as pd

ALPACA_API_KEY = AAA
ALPACA_SECRET_KEY = BBB
APCA_API_BASE_URL=https://paper-api.alpaca.markets
ALPACA_PAPER = True

class SmaCross(bt.SignalStrategy):

2- I am receiving the following error when I try the above
this bit took my attention, do I need another process other than copying the API key from my alpaca account

"ValueError: ('Key ID must be given to access Alpaca trade API', ' (env: APCA_API_KEY_ID)')"

ALPACA_API_KEY = AAA
ALPACA_SECRET_KEY = BBB

I think you are going to want:

ALPACA_API_KEY = "AAA"
ALPACA_SECRET_KEY = "BBB"
APCA_API_BASE_URL= "https://paper-api.alpaca.markets"
ALPACA_PAPER = True
