Why the daily limit of staple fiber and PTA
　　doubled continuously? Cotton and energy chemical futures also want daily limit?
　　It is because oil hoarders re-buy huge amounts of money and do more to form an
　　upward trend, and the seller's stop loss intensifies the trend, while chasing
　　more strengthens the trend! Futures exchanges have destroyed the empty side by
　　adjusting the margin and the fluctuation range! Or are huge sums of money from
　　all walks of life making a lot of crude oil? Beware of sudden shutdown in
　　oil-producing countries, resulting in short supply?
