The difference between this method and the downward price difference method and the upward price difference method is that there will be a round trip on the same day, while the upward and downward price difference method may not necessarily be a daily operation and can be done in a few days.
The methods are the same as the downward price difference method, upward price difference method, and single day methodT+0法相同,但不是全仓进出,而是半仓进出。这样做的好处在于可以防止出错,假如你对后市的判断是错误的,还能保证手中有半仓股票半仓现金,处理起来会比较灵活。
