Don't have much evidence to support this idea, just a scenario that could play out.
My thought is, since price left 4200 so fast in one long green candle, there is a good chance a large supply of buy orders sit around that price. The retracement to this zone could happen quickly, or take months. I, personally, am waiting to buy more around this area. I will be sad if I'm wrong and price continues to rise from where it's at and never come back, but in that situation I will wait for a pull back and determine a good price to get in then.
A longer fib line from the last low also shows the .618 retracement line match up nicely with the open of the large candle.

Added a 50 week Moving average and a 200 week Moving Average (350 period, 1400 period on the daily). Price reacts to this lines strongly. Something to keep an eye on.
