I've installed ta-lib via homebrew and ran into an attribute error when trying out the example

self.sma = bt.talib.SMA(self.data, timeperiod=self.p.period)

AttributeError: 'module' object has no attribute 'SMA'

Obviously ta-lib is not being located. Given that its installed via homebrew, its in /usr/local/Cellar/ta-lib. How can it be resolved? Thanks in advance.

My algo currently makes multiple buys (self.buy()) but when a sell/stop is hit, the positions are sold separately at different times (using self.sell()). How can I sell all the open positions at once in one order?
