How To Understand The Bollinger Line

　　 Boll It is one of the technical indicators frequently used by professional investors and some old shareholders. This index is a path indicator. Price of stock 通常在上限和下限的区间之内波动.动态钱龙的布林线由3根线组成,即下限为支撑线,上限为阻力线,还有一条中线为中界线.静态钱龙的布林线由4根组成.最上面的一条 线是趋势阻力线,称为bolb1,用白色实线表示;最下面一根线是趋势的支撑线,称为bolb4,用紫色实线表示;bolb1之下设有bolb2,有黄色虚线表示;紧靠bolb4之上的另一条线称为bolb3,有浅蓝色实线表示.在4根线构成上限,下限,次上限,次下限,股价通常在这个带状区间内上下波动,这条带状区的宽窄随着股价波动幅度的大小而变化,股价涨跌幅度加大时,带头区会变宽,涨跌幅度缩小时,带状区会变窄.布林线的宽度可以随着股价的变化而自动调整位置.由于这种变异使布林线具备灵活和顺应趋势的特征,它既具备了通道的性质,又克服了通道宽度不能变化的弱点.

The Boolean line has the following major functions:

1, the braid line can indicate the support and pressure position; 2, the brin line can show overbought and oversold; 3, the brin line can indicate the trend; 4, the brin line has the channel function.

The Boolean line is very effective and convenient because it has many functions. Once it is grasped, its signal is clear and its usage is flexible. Investment It is also one of the most commonly used technical indicators in the international financial market.

I. technology and methods used in the normal range.

The normal range is usually the price band running in a certain width of the band range, it is characterized by the stock price did not go up sharply and fall, in a relatively balanced state, at this time, the use of the Boolean line method is very simple.

1, when the stock price crosses the upper limit pressure line (the dynamic upper limit pressure line, the static upper pressure line bolb1), the selling point signal;

2, when the stock price goes through the lower limit supporting wire (the dynamic lower limit support line, the static bottom support line bolb4), buy the signal.

3, when the price goes through the middle boundary from bottom to top (static bolb4 crosses bolb3), the signal is overweight.

4, when the price goes up and down the middle boundary line (static bolb1 crosses bolb2), it is a selling signal.

Two, the use of the Boolean line in the unilateral rising market.

In a strong market, the stock price rises continuously, usually the stock price will run between bolb1 and bolb2. When the share price rises for a long time, the stock price will wear bolb1, the next day will wear bolb1 again, and further break bolb2, drive the bolb1 curve, appear the obvious inflection point from rising to leveling, at this time is the selling signal.{page_break}.

Three, the meaning of necking:

1, when the stock price falls after several waves, it often becomes a long narrow schedule. At that time, we find that the upper and lower limit of the brin line is very small and narrower. It shows that the highest price and the lowest price difference of the stock price are very small. There is no profit margin in the short line, and even the fees can not be earned. The trading volume is not active and the volume is scarce. Investors should pay close attention to this contraction because a big market may be brewing. Once the volume increases, the stock price will rise, the opening of the brin line will expand and the market will start.

2, if the brin line is opened at a high level, once the share price is broken down, the Boolean line will be enlarged.

.

Four, the meaning of the opening of the brin line:

1, when the stock price rises from low to high, the maximum pressure line and the lowest supporting line of the Bollinger line reach a maximum degree, and the opening can not be enlarged until it is contracted. At this time, the selling signal is sold, usually followed by a sharp fall or adjustment.

2, when the stock price has fallen sharply through several waves, the opening of the upper and lower limits of the brin line can not be enlarged. The upper limit line of the brin line will be upwards and downwards from the top to the bottom. When the brin line's lower limit line is lifted from the bottom to the top, a downward trend will come to an end.

Five, matters needing attention in using the Bollinger line

1, the setting of Bollinger parameters should not be less than 6, the static dragon value is usually 10, and the dynamic Qianlong set is usually 20..

2, the use of Bollinger line should pay attention to whether it is in the normal or abnormal area. In the abnormal area, we should not simply sell the upper limit, and break the lower limit.

3, the use of openings to narrow down, easy to capture cattle at low positions, but at high or once the necking down, the stock price to break down, often there is a big drop in space.

4, the Boolean line and other indicators can be used together, and the effect will be better, such as volume, KDJ index and so on.
