Python程式碼：使用TCP SOCKET API接收NYMEX全推原油即時行情

contact email: twtpcc@gmail.com

NYMEX全推原油即時行情是一種提供美國原油期貨市場的最新價格和交易資訊的服務。這種服務可以幫助投資者及時了解市場動態，做出合理的決策。要使用這種服務，需要通過TCP API與服務端建立連接，並接收服務端發送的報文。本文將介紹如何使用TCP SOCKET API接收NYMEX全推原油即時行情，並提供一個Python程式碼的範例。


TCP API的基本概念

TCP API是一種應用層協議，它基於TCP協議，用於在網路上傳輸資料。TCP API的特點是可靠、有序、面向連接，適合傳輸大量或重要的資料。TCP API的工作原理是，客戶端和服務端之間建立一個TCP連接，然後通過這個連接互相發送和接收資料。資料的格式和內容由應用層協議規定，不同的應用層協議有不同的規則和約定。


NYMEX全推原油即時行情的TCP SOCKET API

NYMEX全推原油即時行情的TCP SOCKET API是一種應用層協議，它規定了客戶端和服務端之間的資料交換方式。客戶端要使用這個TCP SOCKET API，需要先向服務端發送一個請求報文，包含一些參數，如用戶名、密碼、訂閱的市場等。服務端收到請求報文後，會驗證客戶端的身份，並回應一個確認報文，表示連接成功。然後，服務端會根據客戶端訂閱的市場，不斷發送即時行情報文，包含每個合約的最新價格、成交量、開盤價、收盤價等資訊。客戶端收到即時行情報文後，可以對資料進行處理和分析，或者顯示在螢幕上。


Python程式碼範例

以下是一個使用Python語言編寫的程式碼範例，它可以使用TCP API接收NYMEX全推原油即時行情。程式碼的主要步驟如下：


導入socket模組，用於建立TCP連接和傳輸資料。

建立一個socket物件，指定使用IPv4協議和TCP協議。

連接服務端，需要提供服務端的IP地址和埠號。這裡使用的是一個免費測試的IP地址和埠號，如需正式使用，請聯繫服務提供商獲取。

發送請求報文，包含一些參數，如用戶名、密碼、訂閱的市場等。這裡使用的是一個示例的用戶名和密碼，如需正式使用，請聯繫服務提供商獲取。參數的格式和意義可以參考服務提供商的文檔。

接收服務端回應的確認報文，並打印出來。確認報文的格式和意義可以參考服務提供商的文檔。

進入一個無限循環，不斷接收服務端發送的即時行情報文，並打印出來。即時行情報文的格式和意義可以參考服務提供商的文檔。

在循環中加入一個判斷，如果2分鐘未能從服務端收到任何報文，則退出循環。這是為了防止連接中斷或服務端停止發送資料的情況。

關閉socket物件，結束連接。

Python

  1. import socket
  3. # TCP API接收NYMEX全推原油即時行情
  4. # 本程式中只需要加一個判斷，例如2分鐘未能從伺服器端收到任何報文，則退出即可
  5. # 此外，程式異常退出時，批次處理或shell會自動再次啟動本程式。
  6. # 這樣，即可 簡單、可靠地實現 斷線自動重連，且可靠性高
  8. s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  10. # 連接服務端
  11. # 請聯繫 twtpcc@gmail.com 得到 免費測試NYMEX原油期貨的IP地址、埠Port
  12. myIP='socket.twtpcc.com'
  13. myPort=51136
  14. s.connect((myIP, myPort))
  16. # 請求 | 發送資料到服務端
  17. s.sendall(b';uz=2;utf8=1;wt1=0;m=WE;u=twtpcc.com;p=twtpcc@gmail.com;')
  19. # 回應 | 接受服務端返回到資料
  20. while True:
  21.     data = s.recv(1024)
  22.     print(data)
  24.     # 如果2分鐘未收到資料，則退出
  25.     if data == b'':
  26.         break
  28. # 關閉 socket
  29. s.close()

臺灣股票即時行情API介面説明：永豐金證券的API

圖片
作者：Sean Liu      Source:  iT邦 感謝 Sean Liu ， 這篇文章介紹的是 永豐金證券的API。 臺北酷碼科技提供各種API介面支援，需要股票、期貨、外匯即時API介面的， 請聯係小弟：gmail郵箱前綴twtpcc ，謝啦！ 臺灣的券商也有提供股票下單API喔，包含：群益證券、永豐金證券、統一證券...等等，都有提供API下單的服務，其中有提供Python介面的券商有群益證券及永豐金證券，因為筆者本身是用永豐金的帳戶，下面會使用永豐金證券的API作為範例，當然大家也可以多方嘗試各家券商的API喔。 Shioaji GitHub Shioaji是永豐金證券提供的API介面，提供報價、下單功能，官方的 Document 還算蠻詳細的，接下來就會照著這個Document來用用看它的功能。 安裝Shioaji 就跟一般python套件一樣，一行就安裝了。 pip install shioaji 初始化 要使用券商的API的話，需要有： 券商帳號：login的時候會用到 下單憑證：有券商帳號後，下載電腦版的下單軟體，它就會請你下載憑證(.pfx檔案)，下面載入憑證時，就指定憑證檔案的路徑即可。 # 載入shioaji套件 import shioaji as sj # Initialization api = sj.Shioaji() # Login accounts = api.login( "YOUR_PERSON_ID" , "YOUR_PASSWORD" ) # 載入憑證 api.activate_ca( ca_path= "/c/your/ca/path/Sinopac.pfx" , ca_passwd= "YOUR_CA_PASSWORD" , person_id= "Person of this Ca" , ) Stock Contract 不管是要取得報價或是下單，要告訴電腦說你想看什麼商品，contract物件就是用來代表商品內容的，所以stock contract就是用股票當作你要查報價或下單的商品。 假設我今天對0050有興趣，可以這樣寫： In contract_0050 = api....

江恩分析圖表的處理 Taipei Cool Code

     多種不同類型的江恩分析對股價分析有不同的影響。臺北酷碼在此間有多年的經驗，愿與同好分享。      包含四方形、輪中輪、六角形、四分圖、數字表、偶數表。可調起點、間隔、週期、方向。      深得市場炒家崇拜的江恩，認為各種趨勢的形成都可以預測，他相信市場存在某種秩序，市況盛衰皆有特定軌跡和紀律，因而發展了一套市場循環理論。      江恩理論一向被譽為技術分析的王道，由其對趨勢轉捩點的掌握更是令人讚嘆。由於應用上混合了占星學與黃金比率，這無疑增添了江恩理論近乎玄學的成份，亦導致外界對之產生質疑與爭議。然而，以預測為本的理論，最重要是經得起不同市場實際走勢的驗證；而江恩亦以高獲利率戰績，成功證實其理論的精準和強大。      江恩理論指出，市場的時間與價位，存在著數字及幾何的關係，其中江恩角度線（Gann Fan，下稱「江恩線」）是最廣為人熟悉及採用的工具。      江恩說過：「當時間與價位形成四方形，市場轉勢便會迫在眼前。」這一句表明了江恩線並非一般意義上的趨勢線，它不只是分析價格的工具，更是同時具有時間和價格兩度空間的強大分析工具。     如閣下有意需要對特點股票、期貨、外匯走勢做江恩研究，歡迎來郵：twtpcc@gmail.com
