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區(qū)間之內波動.動態(tài)錢龍的布林線由3根線組成,即下限為支撐線,上限為阻力線,還有一條中線為中界線.靜態(tài)錢龍的布林線由4根組成.最上面的一條 線是趨勢阻力線,稱為bolb1,用白色實線表示;最下面一根線是趨勢的支撐線,稱為bolb4,用紫色實線表示;bolb1之下設有bolb2,有黃色虛線表示;緊靠bolb4之上的另一條線稱為bolb3,有淺藍色實線表示.在4根線構成上限,下限,次上限,次下限,股價通常在這個帶狀區(qū)間內上下波動,這條帶狀區(qū)的寬窄隨著股價波動幅度的大小而變化,股價漲跌幅度加大時,帶頭區(qū)會變寬,漲跌幅度縮小時,帶狀區(qū)會變窄.布林線的寬度可以隨著股價的變化而自動調整位置.由于這種變異使布林線具備靈活和順應趨勢的特征,它既具備了通道的性質,又克服了通道寬度不能變化的弱點.

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.
