The chart displays a clear uptrend since early March, climbing steadily from the mid-600s. That green Supertrend line at $656.65 is acting as dynamic support now, and price is well above it, which keeps the bias positive. We also see higher highs and higher lows forming, with the latest push rejecting lower around the $670 area.

On the oscillators, StochRSI is at 63.61 and MA StochRSI around 59.90, so we're in bullish territory but not overbought. Williams %R is at -20.40, which suggests we're not quite at extreme upside exhaustion either.
Immediate resistance sits near the recent high of $687–691. A clean break there could open the door toward $700+ in the short term. Support to watch is the Supertrend at $656–660; a dip back there would likely be bought if the trend holds.
