Stock--Commonly used indicators 【上】
Fourth, stock selection also requires psychology-PSY
1 Introduction
The stock market seems to be a programmatic transaction, but behind the programmatic trading in the stock market is a mapping of people's ideas. Each leek is easily affected by other leek, for example, "chasing up and down" is a reflection of the sentiment of most investors.
PSY's English name: Psychological
Chinese name: Psychological line indicator
Function: It reflects the psychological expectations of investors by calculating the proportion of the number of days that rise within 12 days. [It only calculates the level of the closing price]
Remarks:
1. As long as the closing price is higher than the previous day, it will be considered as rising. Rising means that most investors are bullish, and falling means that most investors are bearish.
2. Generally speaking, PSY will fluctuate between 25-75, that is, within the past 12 trading days, it is normal for the number of days to rise within 3-9 days. Below 25 is oversold and above 75 is overbought. Regardless of whether it is oversold or overbought, the strength of both the long and short sides may reverse.
3. PSY only calculates the number of days of change. If the increase or decrease is too large, it may quickly callback.
When the stock price plunges at a low level or regains its 5-day moving average, it can open positions on dips and wait for a rebound to occur. Using this method to spy on the short-term top and bottom is still very accurate.
Always be alert to downside risks and avoid being extremely sad. If you fall below the 5-day moving average, you can reduce or clear the position to keep short-term profits.
2. Use of PSY bottom detection function
When the value is less than 25, and PSY crosses the PSYMA average from bottom to top. Then as an ultra-short line, you can use a wave of admission.
Special attention is required: the ultra-short-term market is short, and you can run when you earn money! Don't be greedy ~
Fifth, catch the oversold rebound tool-DMI
1 Introduction
This is an indicator of autocratic oversold. It is the only "super turn" among many indicators, which can lonely send out risk warning signals when extreme stock markets appear.
Benefits of using it:
If we can notice this signal, first we can avoid the devil operation bought at the top.
Secondly, in the fear of falling, use reason to seize every opportunity to rebound.
Then let's take a look at it:
2. Introduction to DMI Basic Line
They are divided into two gangs:
PDI and MDI belong to long and short indicator groups, ADX and ADXR belong to trend indicator groups, the scale of the table is 0-100, indicating extremely weak to extremely strong.
- PDI--represents the position of multiple parties in the market. The higher the PDI goes, the stronger the current market is, but A shares are often demonish, and it is easy to go to extremes. Therefore, PDI sometimes falls to near zero. At this time, it is often said that a new round of rebound and rising market is about to start.
- MDI--represents the position of the short side in the market. The higher the MDI, the weaker the current market. Before the advent of a big bull market, MDI fell to a low level. At this time, the bears in the market have no power to fight back.
PDI and MDI have a good relationship and are easy to intertwine. If PDI is above MDI, the market is in a strong position. On the contrary: MDI above PDI is a short market. The closeness of the two indicates that the market is in a stalemate of consolidation. The more the points are divided, the more obvious the unilaterality of the market will be. There is no midway adjustment when rising, and there is no rebound correction when falling.
- ADX--Quickly turn back to pulling force, as long as there is a unilateral market, it will run upward. As long as it is intertwined with PDI and MDI, there is no point in using ADX to judge the market. Once the market breaks through and begins to go to extremes, whether the market is rising or falling, ADX will start to run upwards and issue an early warning of the upcoming turn.
- ADXR--Slow pull back force, ADXR is the moving average of ADX value, when ADX runs upward, ADXR also moves slowly upward. In my opinion, its function is to confirm whether the signal sent by ADX is accurate, so there is some lag.
Small summary: PDI and MDI are based on current market trends; ADX and ADXR are based on market strength.
3. The actual combat function of DMI:
- Judging the market trend
When PDI gradually increases, the ADX value also continues to increase, indicating that the current is an upward trend and will be very strong. Conversely, when the MDI gradually increases and the ADX value continues to increase, it indicates that the current is a downward trend and will accelerate. - Judge whether the market is consolidating.
When the market is consolidating slightly in a certain area, all four lines are running below 50, and they move in a narrow horizontal direction, indicating that the trend is not clear in the consolidation state. It should be based on wait-and-see, with no operational value. - Determine whether the market is turning.
When the ADX value changes from high to low at the high point, it indicates that the market is about to reverse.
In addition to the above 3 points judgment function, the most important thing for DMI is to capture the rebound function, which requires the help of good friend PSY.
As mentioned earlier, a small PDI value means a decline in the market. When the PDI is less than 5, it means that the stock is already in a state of oversold.
At this time, you can pay attention. If the PSY reaches 25 or below at the same time, it means that the market is overly pessimistic. At this time, you can accurately select the stocks that are about to rebound.
Pick the stocks and wait and see the first Yang Xian buy. When ADX turns its head down, it means the end of the rebound and direct shipment! In fact, this method can also be verified with many indicators, such as the lower rail support of the Bollinger Bands.
Special attention: the resonance between indicators will greatly improve the accuracy!
The selected stocks can also be viewed in combination with the sector, the hot sector should pay special attention to it!
Sixth, catch the oversold rebound tool-Bias rate BIAS
1 Introduction
As the so-called general situation in the world, the long time must be together, the long time must be together.
This is true in the world, not to mention the stock market. Long time will fall, and long time will fall. The world's division depends on heroes, and there are many ways to look at the stock market's ups and downs. Next, let's talk about one of them--deviation rate.
The deviation rate is the percentage of the gap between the closing price and a certain moving average.
Any moving average is fine. In the simplest and more commonly used 5-day moving average, when the stock price is much higher than the 5-day moving average, it means that the "5-day moving average deviation rate" is very large, which is a short-term selling opportunity.
Because the 5-day moving average can quickly reflect the movement trend of stock prices, it is a strong market lifeline. When the stock price breaks upward, it has a supporting effect, and when the stock price falls downward, it has a pressure characteristic.
The deviation rate of the K line above the moving average is positive, otherwise it is negative.
2. Operating principle
When the stock price deviates too much from the average market cost, the investor's psychological factors make the deviation return.
The greater the positive deviation rate, the more profitable the stockholders, and the easier it is to make money and leave. So the subsequent stock price will fall, and this is the perfect selling point.
The greater the negative deviation rate, the greater the loss of stockholders, and those with ambitions will get the bottom. The stock price naturally rises, and a better buying point at this time.
Usually, after the plunge or surge, the index will be a certain distance away from the 5-day moving average. The large-cap stock price index exceeds 2%, and the small-cap stock price index exceeds 4%. There is a high probability that the oversold rebound will be triggered. [This standard is only applicable to the market where the volatility is not very large. In 2015-2016, when the volatility of A shares is relatively high, this standard is about 5%] This is not a rigid number. The standard in the turbulent and peaceful years is not same. In short, it is very reliable to judge the short-term oversold rebound and overshoot reversal with the deviation rate. With the long and short Bollinger indicators of the withdrawal channel, long and short lines, support lines and pressure lines, the effect is better!
In addition, it should be noted that if the overall trend is in the downtrend channel, even if there is a high negative deviation rate, the rebound will be fleeting. At this time, grab the theme to make quick money and sell it on the next day.
Don't be greedy, be careful. The parameters of individual stocks and the broader market are different. Large-cap stocks can be modified by referring to the parameters of the large market. Don't look at the deviation rate for small-cap stocks that fluctuate too much. It is easy to be fooled without understanding the stock!
Remarks: I use the deviation rate as a short-term indicator, because the long-term does not make much sense in a bear market, so I only need the 5-day moving average deviation rate. How to adjust it? You only need to change all three parameters to 5 as shown below:
7. Easy-to-use indicators are so simple-SAR
1 Introduction
Have you noticed that stock trading does not speak a few English words, and you can't even understand the indicators?
So let ’s learn a few simple words first:
- stop--The meaning of end and stop
. What needs to stop in the stock market? Of course it is lost! So the "stop" in the stock market is the stop loss.
Before buying or selling stocks, you must set a stop loss level to reduce investment risks. The stop loss should be adjusted with the fluctuation of the stock price, which can control the risk without losing the banknote.
How to find a balance between the two? The SAR indicator can be easily solved, as long as the situation changes from red to green, it is necessary to stop the loss.
- reverse--Reverse Reverse means
only operations in the stock market can be reversed. The reverse operation is when the price reaches the stop loss level, throw out the stock and wait and see the currency.
Then when the stock price rises above the pressure of the stock price shown by the SAR indicator, quickly buy the stock and hold the stock to rise.
2. SAR combat operations
It is a multi-functional indicator. In the short term, instruct us to buy when SAR is red and sell when it is green.
SAR can perfectly grasp the reversal point of the broad market and individual stocks.
Let's take an example:
set the analysis period of the Shanghai and Shenzhen 300 Index to weeks, buy 300 ETF (trading open index fund) when SAR is red, and sell 300 ETF when green. Suppose that with 10,000 yuan in admission in 2005, the big bull market experienced in 2006 and 2007, a sharp decline in 2008, a violent rebound in 2009, and a long bear market from 2010 to 2013, 2014 to 2015 The unilateral market, a sharp decline from 2015 to 2016, and then to the slow bull in 2018, and now.
If (note! Here is if!) You go according to the SAR indicator, red entry, green short position, each entry is 10,000 yuan, and your current income is 88,000 yuan.
If you invest the money you earn every time, your benefit will be 620,000 yuan! ! !While buying the Shanghai and Shenzhen 300 held in the same period, 10,000 yuan became 48,000 yuan.
Therefore, whether it is 88,000 yuan or 620,000 yuan is too much 48,000 yuan.
3. Small summary
There are two reasons for SAR's victory:
- Caught all bull markets;
- Avoid all bear markets.
As a multi-function indicator, the rising angle of SAR should also be noted in the short-term.
The angle of the curve running downward is too large, indicating that the decline is relatively rapid and will continue. At this time, you must not enter the field to grab a rebound, otherwise you will be shot and killed on the beach.
The downward running angle of the curve gradually becomes smaller. Once the stock price breaks through the SAR curve upwards, it indicates that the mid-to-long-term downtrend may end. At this time, it is necessary to flexibly buy on dips.
When the upward angle of the curve is too large, just running upward indicates that the stock price will continue to rise. At this time, you can welcome hope as long as you stabilize it.
If the curve has been running upward for a long time, and the stock price rises too much in the short term, it means that the stock price may reverse at any time.
and so! Once the SAR sends a clear sell signal, it should resolutely leave the market.
The medium- and long-term index used in the Shanghai-Shenzhen 300 index, which is relatively difficult to change, can be said to be quite practical.
It's not a big ticket in the shock, and it's confused.
However, in the unilateral rise and fall, the advantages are most clearly reflected.
Isn't it great to let the profit run and stop the loss in time? When you are in a bear market, you dare not start, and you are afraid of missing a rebound or reversal that may come at any time. It is recommended to try this strategy!
