I mapped out this decline on January 20th in the Key Hidden Levels Chatroom here at TradingView.
Without going into extreme detail at this moment, I am looking for a decline over the next 4-5 weeks to potentially see the price fall to $260 from $393 at the moment.
There is tremendous distribution in the chart pattern, especially as shown by RgMov, my proprietary "trend" indicator which has been hitting new lows here lately.
$450 is the current stop but that can come down pretty quickly.
