Hi, I am very new to QuantConnect and stock trading in general and I am just trying to figure everything out. I have two questions: How realistic are the returns of algos and how can I achieve a positive return with a negative profit? I sometimes see algos posted in this forum that has a 10000% plus return in 3 years while having negative profit. How is it even possible? Sorry for these newbie questions. Any help will be appreciated. Thank you.
