The S&P 500 broke through resistance at 1700/1710, indicating a primary advance to 1790/1800*. Troughs close to zero on 21-day Twiggs Money Flow suggest buying pressure. Reversal below 1675 is unlikely at present, but would warn of a test of primary support at 1630.
* Target calculation: 1710 + ( 1710 – 1630 ) = 1790
