Broker position Error

[sirhc78]

Hi,
Using Bitmex feed and Bitmex broker on BTC/USD production. (same before and after 0ce07e5)

I have a strange position object.
First self.getposition().size does not exist :

  File "D:\Dev2\Anaconda3\lib\site-packages\backtrader\strategy.py", line 325, in _next
    super(Strategy, self)._next()

  File "D:\Dev2\Anaconda3\lib\site-packages\backtrader\lineiterator.py", line 266, in _next
    self.next()

  File "D:\Dev2\Dev\JimTrading\BTStrategies.py", line 150, in next
    if self.getposition().size>0:

AttributeError: 'float' object has no attribute 'size'

And if I run :

    def __init__(self):
        print(self.getposition())

I get a float :
0.01
which seems to be the account value and not my position on future perpetual contract XBTUSD.

Could it be CCXT error ?

My Strategie code is working correctly on pandas feed.

May be I don't understand how it should work.

if self.position : is true. I should get a structure with size and price members and not a float.
Is that correct ?

It's a bug that has to be fixed. The getposition method should return position object. I'll fix it when I have time. You can fix it too :)

Hi,
I was just wondering if this bug has been fixed. When i use the self.getposition() i receive empty object where I should get a list of my open positions.

Positions --- Position Begin

• Size: 0
• Price: 0.0
• Price orig: 0.0
• Closed: 0
• Opened: 0
• Adjbase: None
  --- Position End
