SMH Daily a Break of 143.50 is "Katy Bar the Door"

Tomorrow, 8/18, is a critical day for Semis. Should the selling continue, to the tune of -1.38% off today's close, and we could see a break of a key Gann Confluence support at 143.50 (middle circle), which is a prior pivot (left circle).

Below that area is free-fall (yellow highlighted), low volume, and little support. The 136 area I had pegged a while back on another chart.

IF selloff continues tomorrow, we could have an interesting setup for Monday.
