在告訴你答案之前，先簡短的講講我的經歷吧！十多年前，我是世界500強企業的一名職員。通過自學，考試後現在轉行為證券公司的一名投顧。在我轉行之前也是到處找資料學習。相關的書籍啊，指標啊等等，但掌握了一些基礎知識後發現即使學會了這些東西還是遠遠不能在這個市場上生存的。通過認真思考我發現，如果做投資沒有自己的交易體系，那是很危險的一件事。在自己的交易體系建立之前，我做過外匯，做過權證，做過商品期貨，做過期權，當然也有股票。現在從業了，所以也就只是做做股票的模擬盤。所以對於指標類的東西還是有所發言權的。言歸正傳，下面來回答一下你的問題吧！

1.如果你真的想在這個投資市場上暢意的行走，你首先應該建立自己的交易體系。

2.在你建立交易體系之後，我現在正式回答你的問題。正常情況下，你只需要認真研究系統默認的幾個指標就可以了，K線，均線，量，KDJ，MACD就這幾個，其它雜亂的指標都是通過這幾個基礎指標編輯演變而成的，因為是手機截圖，所以這里截了兩個圖，如果需要操盤，建議最好是用電腦。

3.K線，K線就是紅綠柱，他代表最高價，最低價，開盤價和收盤價。在這里我就不詳細贅述了。

4.均線，均線分日，月，周，季，年均線等。那要看你是什麼周期，比如日均線m5就是五天內的平均價，也就是五日均線。M10就是十天均線等等。

5.量，量就比較復雜一點，常常需要配合其他指標使用，它代表成交量或成交額。周期也是和均線一樣。

6.MACD和KDJ，同樣需要結合周期來使用，最常見的就是金叉和死叉，但是也需要結合市場環境來看。

給大家一個去掉不適合自己參與的過濾選股器吧，懂代碼的可以自己修改，不懂得那就直接用，有幾個參數最好自己做一下修改，比如，股價，交易密度，等等。

它的功能是選出適合自己的帶有漲停板的活躍股，他不是操作的依據，只是幫你過濾掉那些不適合參與的股票，每天盤後下載數據，復盤選股，他不適合最預警，只適合復盤高效選股。

「獵庄擒牛」指標要點：

一、指標提示「莊家出現」信號時，表明監測到此處有莊家大資金進場，行情即將開啟拉升，可跟進建倉。

二、指標提示「莊家出貨」信號時，表明監測到此處莊家在進行籌碼派發，應果斷止盈離場，落袋為安。

效果圖：

「獵庄擒牛」主要作用就是對莊家大資金動向的監測，從而給出預警信號。當然指標還有其它關於籌碼和趨勢的信號判斷，這里就不做過多講解，大家拿到後可以去慢慢摸索。

大道至簡，簡單有效不要復雜。股市中最有效的技術指標就是那些最貼近市場本質的數據跟蹤指標，我最常用的就是K線，均線，MACD和量能及均量線，夠用了。

在一個多變復雜的市場中，越簡單反而才是越有效，過於復雜的技術工具適應能力太差。

好用的公式有很多，但是適合自己才行！今天我分享幾個我自己經常用的公式分享給大家！

這個公式主要就是抓買賣點的指標，不含未來函數，可以放心操作！

該公式是精準判斷操作位置，依然沒有未來函數！

其次，如果大家想炒股，先學習一些基本的炒股知識，並且少量投入，切不可一梭哈。不要迷信技術指標，所謂的指標都是事後才出來的，有精力的可以去看看指標編程，無非都出自於成交量、成交額、均線等等，所以都是滯後的。簡單的K線、成交量、2條均線，輔助參考判斷即可。技術指標越復雜，越難以付諸實施。

所以，還請大家不要迷戀技術指標，我曾經花了1年多的時間研究、編寫各種技術指標，到現在，我已經放棄了，只留了交易軟體裡面最原始的指標，做輔助判斷而已，記住只是輔助判斷。還請大家不要走彎路，一入股市深似海，到處都是坑，切記！！！

這個我認為因人而異，畢竟適合自己的指標才是好指標。這里我們來分享下我常用的指標

第一，均線，均線是時候非常實用的指標，無論是短線，中線，長線都非常實用。

（1）如果是短線，5日均線就夠了。5日均線比較神奇。

①當K線從5日均線下方上穿5日均線，而且均線開始拐頭，結合量能，底部放量，那麼短線就可以把我了，而且是超短機會。基本都有不錯的收益。

②當市場均線多頭排列，只要K線在5日均線上方，沿著5日均線上行，那麼也是一個持倉的機會。

（2）中線，中線一般就是看20日均線，這個均線比較實用，也稱為萬能均線，只要K線站穩在20日均線上方，而且拐頭向上，結合籌碼，籌碼低位單峰，中線就可以把握。

（3）長線，長線就是60日均線上穿120日均線，而且趨勢上行。

第二，MACD，領略到精髓，賺錢非常簡單。

1、 MACD在0軸上方——每發生一次金叉，股價將創新高，但是二次金叉不要追。2、 MACD在0軸下方——每發生一次死叉，股價將創新低新低後可以適當的補倉。3， MACD在0軸上方——金叉死叉次數越多越好、牛股,4,, MACD在0軸下方——金叉死叉次數越多越差、熊股。5,MACD水下兩次金叉，第二次金叉就是買入機會。6.MACD的黃白兩線不能和柱狀形成背離，背離則會產生行情反轉。

好了我就分享了我常用的這兩個希望對大家有幫助。

如果想聽實話，我就告訴你。最好用的指標是：K線、成交量(手)、均線和MACD。其它指標都可以忽略。

你進入叢林，容易繞花眼睛，七選八選-選個漏眼。其實最顯眼的就是最好的。

⑤ 請教一下，三菱PLC的通訊指令ADPRW S S1 S2 S3 S4/D各代表什麼。

ADPRW代表指令的使用

S代表從站的站號，例如要與1號站通信，S的位置就填寫H1。

S1是MODBUS的命令代碼。

S2是MODBUS軟元件的地址。

S3是設置從S2設置的MODBUS軟元件地址開始的幾個地址。S1如果使用寫的命令代碼，就代表從S2地址開始寫入S3個地址；S1如果使用讀的命令代碼，就代表從S2地址開始讀取S3個地址。

S4/D：S1如果使用寫的命令代碼，標記S4，表示把S4設置的軟元件的數據寫給從站；如果使用讀的命令代碼，標記D，表示把從站的數據讀到D設置的軟元件中。

三菱公司PLC網路繼承了傳統使用的MELSEC網路，並使其在性能、功能、使用簡便等方面更勝一籌。Q系列PLC提供層次清晰的三層網路，針對各種用途提供最合適的網路產品.

1、信息層銀鋒虧/Ethernet（乙太網） 信息層為網路系統中最高層，主要是在PLC、設備控制器以及生產管理用PC之間傳輸生產管理信息、質量管理信息及設備的運轉情況等數據，信息層使用最普遍的Ethernet。

它不僅能夠連接windows系統的PC、UNIX系統的工作站等，而且還能連接各種FA設備。Q系列PLC系列的Ethernet模塊具有了日益普及的網際網路電子郵件收發功能，使用戶無論在世界的任何地方都可以方便地收發生產信息郵件，構築遠程監視管理系統。

同時，利用網際網路的FTP伺服器功能及MELSEC專用協議可以很容易的實現程序的上傳/下載和信息的傳輸。

2、控制層/MELSECNET/10（H） 是整個網路系統的中間層，在是PLC、CNC等控制設備之間方便且高速地進行處理數據互傳的控制網路。

作為MELSEC控制網路的MELSECNET/10，以它良好的實時性、簡單的網路設定、無程序的網路數據共享概念，以及冗餘迴路等特點獲得了很高的市場評價，被採用的設備台數在日本達到最高，在世界上也是屈指可數的。

而MELSECNET/H不僅繼承了MELSECNET/10優秀的特點，還使網路的實時性更好，數據容基咐量更大，進一步適應市場的需要。

3、設備層/現場匯流排CC-Link 設備層是把PLC等控制設備和感測器以及驅動設備連接起來的現場網路，為整個網路系統最低層的網路。採用CC-Link現場匯流排連接，布線數量大大減少，提高了系統可維護性。

而且，不只是ON/OFF等開關量鋒神的數據，還可連接ID系統、條形碼閱讀器、變頻器、人機界面等智能化設備，從完成各種數據的通信，到終端生產信息的管理均可實現，加上對機器動作狀態的集中管理，使維修保養的工作效率也大有提高。在Q系列PLC中使用，CC-Link的功能更好，而且使用更簡便。
