Bulls can draw a line in the sand as long as they can hold intraday levels. Kevin Green notes the ways they can gain ground on today's session but face volatility headwinds until the closing bell. One sign of weakness comes from the U.S. Dollar as it trades under $100. Turning to individuals stock movers, he talks about Tesla's (TSLA) decision to stop taking new orders for its Model S and Model X cars in China. Kevin also notes Wells Fargo's (WFC) mixed earnings as a signal headwinds are brewing for consumer strength.
