SPY/SPX's much lower low:
SPY and ES are calculated and managed very differently. SPY is a closer approximation of the 500 stocks in S&P's list (or at least it's supposed to be).
Indeed. The horizontal axis (time axis) on both charts is very different.I think you are comparing two different time frames. ES is daily and SPY is 240 min (I think). That is why 200 ma looks so different
