A simple pattern that works in any market (Ad)

Right when most traders were getting bearish, The All-Weather Pattern signaled something different. Following this setup could've turned every $1,000 into $1,770 in just 48 hours. But here's what really gets me excited... You don't need to be glued to your screen all day, no complex formulas, no guessing. Just wait for a stock to close below The All-Weather Pattern, then check if it opens higher the next morning. That's it. While of course I cannot promise future returns or against losses… I've put together a complete breakdown of how this works, including the new stock that’s tending towards The All-Weather Pattern this week.
