Seeing massive short term worry about what the Bank of Japan will do tonight, and what the fed will do tomorrow.
If they dont disapoint markets, look for a big pop, if they do disapoint markets, look for a big sell off.
Bottom line: If market react positively to news tomorrow, my gut is to heavily short, especially if sentiment shows no worry. In fact, if that is what happens, i will go heavily margin short by the close.
2160 is major resistance, lets see if we close over that level tomorrow. 2129 major support, really bad news if we close under that level.
Of course, watch for lots of up and down movement right after the fed reports, and possibly at open after B OF J announcement late tonight our time.
