This platform definitely has issues. I tried many times, no matter whether you buy short or buy long, as long as you enter, if you buy short, it will give you a rise, if you buy long, it will give you a drop. It basically controls around your cost line. It will never let you make money. Sometimes when you buy long or short, it will reverse and give you a big move. Causing you to lose your position. When you reverse your buy again, it will reverse again. I tried many times, in short, this platform definitely has issues. It always makes you lose more and win less.
