No danger yet in my eyes, possibly just a re-trace. My stop is close under 253.76 on 4HR chart. The lower long-term trendline is where the real danger is, and that's ~ 208 and rising.
To Note: On last big up-thrust, starting with first green Supertrend signal on 7/17 and second signal on 7/29, the second signal was when the real move happened. So, even if we get a 4HR sell signal it may be a very small correction, I'm buying large on the 2nd 4HR buy signal if the pattern is similar to what happened last time.
