'Position' object has no attribute 'avg_entry_price'

[SeverinJB]

stragey_scalping calls invalid attribute in def function __get_signal(self, data) > cost_basis = float(position.avg_entry_price)

Alpaca strategy requires avg_entry_price.

Fix by

• [x] extending trade_object Position() by avg_entry_price
• [x] storing avg_entry_price as received by trade_update

Fixed with the steps listed above. However, it will have to be optimised if executors behave differently then the current Alpaca.
