$Tesla(TSLA.US) always makes money for a day or two first, then loses money for two or three days. If you catch the rhythm and follow the long or short positions, you can definitely make money. But recently, I don't know what the direction is either. Watching it easily break through $400, as if there's support below, the support level seems solid. It's been continuously opening low and closing high, or opening high and closing low. It's better to stay put and wait for a clear signal before making adjustments.
