Hello! I am new to Quantopian and am having trouble trying to add a trailing stop loss to a multi stock equity long short portfolio, like the sample provided. I have tried a couple of things but I can't get anything to work! Any help would be much appreciated. Thank you
from collections import defaultdict
context.stops = defaultdict(lambda:0)
#call whenever
for s in context.portfolio.positions:
price = data.current(s, 'price')
context.stops[s] = max(context.stops[s], stop * price) this has worked for me, I think I got it from Anthony FJ Garner.
I hope this is what you are asking
