All three major large cap indices (S&P 500, Nasdaq 100 & Dow Jones 30) are all approaching the “sweet spot” of their 60-minute bearish rising wedge patterns where a breakdown typically occurs. The first sell signal of 2018 will come on a break below the uptrend lines on all three of these major stock indices, ideally on an impulsive breakdown and/or 60-minute close below.

I would put extremely good odds that all three indices break down below these wedges no later than tomorrow.
