INGOpening range breakout is one of the most important indicators of daily market direction that a trader can utilize.

开盘区间突破是一个可以用来判断每天市场方向的重要工具。

An opening range breakout (ORB) is a trade taken at a predetermined amount above or below the
opening range. When the predetermined amount (the 'stretch') is computed, a buy stop is placed that amount above the high of the opening range and a sell stop is placed the same amount below the low of the opening range. The first stop that is traded is the position and the other stop is a protective stop.

开盘区间突破（记做ORB）是通过在开盘区间的上下加减预定的数值范围进行交易。当预定的数值范围被确定，这个买点就被放置在开盘区间的最高处或放在最低处的同等数值。一个作为进场点，另一个作为止损点。

The stretch is determined by looking at the previous 10 days and averaging the differences between the open for each day and the closest extreme to the open on each day.
