There are quite a few long positions in the 114500---115800 range, with the largest long position being liquidated at 115700; in the 118400---119900 range, there is a significant short position liquidation at the 118400 price. For every increase of 100 dollars, there is continuous fuel, and when the short positions are liquidated, it means buying to close, which is like fireworks; once ignited, it goes off all at once. Thus, if it rises to 119900/120000, it can blow up most of the short positions in the market.
