Potential Double-Top in Both the Mid and Short-Term

More of an update to my last S&P 500 chart than a chart in its own right, I've left out the drawings already in the previous one. Looking at today's trading, a very short-term double-top looks likely (probably more of a retest than a double-top really). This could in turn confirm the slightly longer term double-top (triple-top?) that's been forming over the last few months.

We're going to be over a weak area of the cloud by the end of the week with the Stoch RSI oversold and a slight bear divergence in the RSI. There's an ambitiously precise forecast here; I don't have much reputation to lose, so why not? Just going on the difference between the intra-top support and the tops, I've predicted a downtrend to 1623 - again, purely speculative.
