I think NIO is a good company, if you get caught high and your a long runner you will be able to get your cash back. I wouldn't sweat it, even if it drops 15%... if your hold it long u will make your money back on this one.
I try to buy just above the supports and then sell just below the resistance lines, but that's me.
Bottom Line I think NIO should be OK in the long run.
Educational advice as always ,,, Good luck traders :-)
