$XPEV's chart is looking a lot better structurally than $NIO, as this has got its Wave B bounce on the 50 Day MA in the middle of August very well, whereas $NIO's potential Wave B has been quite small.
If $XPEV starts moving down now to complete Wave C as show and the price can hold at the 0.618 Fib at $13.70, there is a very good opportunity to add here.
If this does move down too, this may also encourage $NIO to move down with it to $9.
So the area now to watch is 50 Day MA at $16.90, losing this level and we will have confirmation that the price action is in Wave C.
