Close several positions once the reach of a target

Hi,

Have been searching for hours without finding something good enough. Here is my basic and probably not perfect code to buy stocks if it opens at 5 % UP from yesterday's close.

I'm looking to be able to get those open positions closed when they reach +2% and -0.5% from the price paid to buy them. It is simple but I don't know how to recall those opened positions and make the logic with the actual return of those positions.

Thank you for your tips....

Hi Pierre-Luc,

It looks like you are getting an error because you are checking whether exchange_time == a certain value without having defined the exchange_time variable!

Also, in the bit of code and the bottom of your algo, it looks like you are setting an if condition that will never become true:

''' if stock_return <= 0.95 and stock_return >= 1.05 and current_position > 0:
order_target(stock, 0)
'''

stock_return can never be both less than or equal to 0.95 AND greater than or equal to 1.05 at the same time, you probably meant for this to be OR :)

Hopefully this helps!

Jamie,

You are damn right. Thanks ! I made the correction but I still get the error I as talking about :

AttributeError: 'zipline.assets._assets.Equity' object has no attribute 'cost_basis'
... USER ALGORITHM:47, in handle_dataGo to IDE
stock_return = (data[stock].price - stock.cost_basis) / stock.cost_basis

Hi Pierre-Luc,

I made a few other changes to your code to get it to run. It looks like you were also mixing up current_position and stock when trying to get cost_basis. You should also make sure to check that previous orders have gone through (i.e. the stock is not in get_open_orders()) before trying to place orders with the same security -- I added this check.
