Stop loss orders, not even once!!

I mean I say this in joke form but I mean it in all seriousness. Using stop loss orders is a sign of someone who doesn't know what they are doing.

They just aren't suitable for markets anymore. Well they haven't really been suitable for the past 10 years but atleast now the major markets are finally no longer allowing retail investors to use that order type.

Please don't ever use stop loss orders.



I'm not buying your conclusion that stop-loss orders don't work and a sign of somebody who doesn't know what they are doing.

Sure, assuming there is a flash crash your stop-loss will convert to a market order and if you are using a big name brokerage you order will get filled (maybe delayed, and most likely at a lower price than institutions, but it will get filled).

What is your background if you don't mind me asking? Do you work in finance or in the market?

My bad/fault, I didn't look. I wasn't trying to be rude or condescending, just curious his background.
