How to add a stop loss if it continues to loss in 4 days

As the title, how to add a stop loss order if it continues to loss in 4 days?
Could you provide an example? Thanks.

create a scheduled function that will check the profit/loss of each security you hold at the first minute of every day, if the gain is negative then add +1 to a counter, if the counter is = 4 then sell. If the gain is positive then reset the counter to 0.

How do I control the draw down?

This is a sample algorithm which does a 4 day stop loss.

Each day, it retrieves the price history for your stock(s). It checks if that price history is consecutively descending, if so, it closes the position.

Hope this helps!

Hi Matthew, this looks like a brilliant code, thanks for sharing it. Please, I'm quite new to Quantopian and I hope you could apologize my simple question.
I see you're running the function "stop_loss" as a scheduled daily function.
When the code executes:
price_data = data.history(context.stock, "price", 4, "1d")
say today is Oct 7th, 2016,
what's the most recent value given by that instruction? is it the open price as of 9.30am of Oct, the 7th?
Also, are you sure it's:
return all(earlier >= later for earlier, later in zip(array, array[1:]))

I get increasing values rather than decreasing, so I'm a little confused.
Many thanks!
