Hello, I am getting this error, can you help me to solve this? Thank you

... get_all_binance("BTCUSDT", "5m", False) File "<stdin>", line 21 get_all_binance("BTCUSDT", "5m", False) ^ SyntaxError: invalid syntax

try setting the save attr like this:

data = get_all_binance("BTCUSDT", "5m", save=False)

For future reference - the prerequisite package: simplejson, which is needed by the Bitmex API wrapper, requires Python 3.7 to function.
simplejson is not compatible with Python 3.9 at this time.
In addendum, the wrapper used for the Binance connection is python-binance by Sam McHardy so be sure to install this wrapper.

The Bitmex function doesn't seem to work. Binance works though.

Thanks Bro, its amazing
