This is the daily chart following up to a long term weekly RSI divergence on the SPY.
While the peaks of the SPY went up, the RSI went down. the following day was confirmation, then profit!
This may still play out further down to 202 or 200 as potential profit points, or may have completed it's drop so that the SPY and RSI are on the same page (so to speak) again and follow each other once more.
