Update `constants.py`

[tameike000]

First, great package!

I tried to use "close_1_days_back" and I get: requests.exceptions.HTTPError: 400 Client Error: Bad Request Body: {"totalCount":0,"error":"Unknown field "close_1_days_back"","data":null}

Seems not existing (anymore).

Is there a way to create an updated constants.py?

Thanks!! M
