Hello, long time lurker first time poster here. I was wondering if anyone has been able to short crypto on GDAX. I am running into 2 issues with the backtester. 

 

The first is that any short limit order I place is accepted but no position is opened.

 

The second issue is that I am unable to use a margin account. I receive the error 

PythonException: Exception : The GDAX brokerage does not currently support Margin trading.

Which is not true since GDAX does have margin accounts.
