$NIO Inc(NIO.US)$ will history repeat itself ? support at 17 and price bounce back up ,luring people in to push the price up and then comes another sell down at 21 -22, pushing it back down . should we follow this pattern and sculp the profits difference between the dip and resistance? many people stuck as their average pricing is 19-20 when they unknowing follow the trend . long term investors buy today and go away ,hold hold hold . short term players may have to change strategy? my 2 cents view
