Speculation is a trading method that uses the margin leverage provided by futures trading and the three advantages of T+0 trading mode plus extremely low handling fees to obtain intraday trading spreads. Simply put, speculation is a mode of operating according to the structure with the smallest price fluctuation. Fried sheets have their own specific adaptation environment. That is, when the market is active and there are big differences between long and short positions, it is most suitable for speculation. Such a market environment generally occurs in the daily opening stage. During this period, the mode of speculation appeared repeatedly and stably. After this time period (9: 30) (intraday), the differences between long and short positions are reduced, forming a stable balance of power, and the trading rhythm of the market changes accordingly. At this time, if you trade in a speculative mode, you can only pay the handling fee. Therefore, the main source of profit for many speculators in a day is the early stage, while the middle plate is the weakness. Many times, although the middle market trend is obvious, it can't make money. This is because, in different market environments, the successful model in early trading becomes noise in the middle of trading. Therefore, how to deal with the trading opportunities in the middle market is a watershed to improve speculators' profits.
