$NIO appears to be in Wave C of a zig-zag correction. As a guideline, we would like to see Wave C end beyond the end of Wave A. The .618 ratio is the first area of value to look for. If that does not hold, then look for Wave C to be around the same length of Wave A, which is also listed at the 100% ratio. The goal is not to hit price targets but to give ourself the best probability and become profitable traders. Will update as time progress.
