捉腰带线是一种金融交易市场有关K线的术语。

捉腰带线是由单独一根蜡烛线构成的，既可能具有看涨的意义，也可能具有看跌的意义。捉腰带形态的日文名称来自相扑运动的一个术语：羚羊挂角。这个术语的意思是“抓着对手的腰带，将他推出圈外”。

“捉腰带线”的英文表达为 Belt Hold，分为Bullish Belt Hold和Bearish Belt Hold。

Bullish Belt Hold是指“看涨捉腰带线”，其英文如下：

A bullish belt hold is a single-day Japanese candlestick pattern that suggests a possible reversal of the prevailing downtrend.

The pattern forms when, following a stretch of bearish trades, a bullish or white candlestick occurs. The opening price, which becomes the low for the day, is lower than the close of the previous day. The stock price then rises throughout the day, resulting in a long white candlestick with a short upper shadow and no lower shadow.

It can be contrasted with a bearish belt hold.

Bearish Belt Hold是指“看跌捉腰带线”，其英文如下:

A bearish belt hold is a pattern that often signals a reverse in investor sentiment from bullish to bearish. However, the bearish belt hold is not considered very reliable as it occurs frequently and is often incorrect in predicting future share prices. As with any other candlestick charting method, more than two days of trading should be considered when making predictions about trends.

以下图解可能理解起来更容易一些：

参见图1，看涨捉腰带形态是一根坚挺的白色蜡烛线，其开市价位于当日的最低点（或者，这根蜡烛线只有极短的下影线），然后市场一路上扬。看涨捉腰带线又称为开盘秃（脚）阳线。如果市场处于低价区域，出现一根长长的看涨捉腰带线，则预示着上冲行情的到来。

参见图2，看跌捉腰带形态是一根长长的黑色蜡烛线，它的开市价位于当日的最高点（或者这根蜡烛线只有极短的上影线），然后市场一路下跌。在市场处于高价区的条件下，看跌捉腰带形态的出现，构成了顶部反转信号。看跌捉腰带线有时称为开盘秃（头）阴线。

捉腰带蜡烛线的长度愈长，则该形态的技术意义越重大。另外，如果捉腰带线是在市场趋势已经发展了较长时间之后才出现的，那么，它的意义也更加重要。
