It provides a wide range of data and analysis tools covering various aspects such as economics, finance, stock markets, bond markets, and futures. With its extensive database and professional analytical features, the TEJ platform is widely used by financial institutions, research units, and investors to access real-time, accurate market data and conduct in-depth data analysis to support decision-making.<\/p>\n\n\n\n<p>As financial markets evolve and data analysis demands grow, TEJ offers diverse economic data services, enabling investors to better organize and analyze data in this era of big data, and even to engage in profitable asset trading.<\/p>\n\n\n\n<p>Among TEJ&#8217;s many services and products, <strong>TEJ API<\/strong>, <strong>TEJ Tool API<\/strong>, and <strong>TQuant Lab<\/strong> are tools designed for data retrieval and analysis. While they all provide robust data integration tools and analysis capabilities, they differ in specific applications. This article will delve into the main features, usage scenarios, and advantages and disadvantages of these three tools, helping users better understand their distinctions and choose the most suitable one for their needs, ultimately enhancing efficiency in data analysis and investment decision-making.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"TEJ_API\"><\/span><strong>TEJ API:<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>As mentioned above, TEJ focuses on acquiring diverse data from economic markets. From basic stock trading data to detailed accounting items, TEJ API encompasses a wide range of content. Users can retrieve specific stock data by selecting the desired database.<\/p>\n\n\n\n<p><strong>Example:<\/strong>By specifying different databases, users can access various datasets. The following example demonstrates using the monthly revenue database (TWN\/APISALE) to retrieve the monthly revenue data of Taiwanese companies for the period from January 1, 2024, to December 31, 2024.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>import tejapi\ntejapi.ApiConfig.api_key ='your tejapi key'\ntejapi.ApiConfig.api_base= \"your base\"\ntejapi.ApiConfig.ignoretz = True\n\n\nstart_date = '2024-01-01'\nend_date = '2024-12-31'\ndata = tejapi.get('TWN\/APISALE',     #\u8cc7\u6599\u8868\u4ee3\u78bc\n                  paginate = True,\n                  mdate={'gte': start_date, 'lte': end_date},\n                  chinese_column_name = True)\nprint(data)\n<\/code><\/pre>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" src=\"https:\/\/www.tejwin.com\/wp-content\/uploads\/2_AD_4nXcvQttP1hKISj0gNh1mfLsHh3sQ70RyY5tb-vZTsaylWgZfZRki2w_T1WETwN_cpr7z4RbIeQsIRshCZ5kY5bX0LRo62new1y6py09mmEzeieV6-g2SLLcoFIIRrY3oYaYDNUHuNAkeyLGOnIfOMZK3zO7b7JfbxwG_w.png\" style=\"\"><\/p>\n\n\n\n<p>For details on the available databases, please refer to the following website: <a href=\"https:\/\/api.tej.com.tw\/index.html\" target=\"_blank\" rel=\"noopener\">Website<\/a><\/p>\n\n\n\n<p>TEJ API primarily provides comprehensive market data, offering single-point data access suitable for basic data analysis, simple data retrieval, and automation needs. It is highly beginner-friendly for those new to working with databases, making it an easy-to-use product for quick deployment.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"TEJ_Tool_API\"><\/span><strong>TEJ Tool API:<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Building upon an understanding of TEJ API, users can leverage various databases to access diverse data types. However, advanced data users often face the challenge of merging and processing multiple datasets, which requires aligning data by time and frequency. For example, when analyzing both monthly revenue and stock closing prices, users must address the frequency mismatch, as monthly revenue is monthly data while closing prices are daily data.<\/p>\n\n\n\n<p>This is where <strong>TEJ Tool API<\/strong> comes into play. It provides services for integrating different types of data, enabling advanced users to skip the manual data consolidation process while ensuring accuracy.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Example:<\/strong><\/p>\n\n\n\n<p>Using the [ get_history_data ] function from TEJ Tool API, users can directly retrieve data for specified fields (as shown in the &#8220;columns&#8221; section of the illustration). This includes data spanning different frequency types, such as trading data (e.g., closing prices), accounting data (e.g., total liabilities), and financial ratios (e.g., current ratio). These datasets, originally of varying frequencies, can be seamlessly integrated into a single table using TEJ Tool API.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>import TejToolAPI\n\n\ncolumns = &#91;'Industry', '\u672c\u76ca\u6bd4', '\u6536\u76e4\u50f9', '\u6d41\u52d5\u6bd4\u7387', '\u80a1\u6771\u6b0a\u76ca\u7e3d\u8a08', '\u8ca0\u50b5\u7e3d\u984d', '\u71df\u6536\u6210\u9577\u7387','eps','mt_div','\u73fe\u91d1\u80a1\u5229\u7387']\n\n\nstart_dt = pd.Timestamp('2015-12-29', tz = 'UTC')\nend_dt = pd.Timestamp('2024-12-31', tz = \"UTC\")\n\n\ndata__ = TejToolAPI.get_history_data(start = start_dt,\n                                  end = end_dt,\n                                  ticker = pool,\n                                  fin_type = 'A', # \u70ba\u7d2f\u8a08\u8cc7\u6599\n                                  columns = columns,\n                                  transfer_to_chinese = True)\n\n\ndata__&#91;data__&#91;'\u80a1\u7968\u4ee3\u78bc'] == '2330']\n<\/code><\/pre>\n\n\n\n<p class=\"has-text-align-center\"><img decoding=\"async\" src=\"https:\/\/www.tejwin.com\/wp-content\/uploads\/2_AD_4nXfAhDHlKPxPGJsUYZnsqWaxk041a2dHapKqNRBKu53ZHCEYeAzQxOZF_K09KYTh4BdhejFYtjexa-VaickH-tUHSH1-OZAjs9WjBYy7gvcY32OW6MB8TIzTqo7bsDr0xn63yIMrPQkeyLGOnIfOMZK3zO7b7JfbxwG_w.png\" style=\"\"><\/p>\n\n\n\n<p>For more information about the fields available in TEJ Tool API, please refer to the following website: <a href=\"https:\/\/tquant.tejwin.com\/%e8%b3%87%e6%96%99%e9%9b%86\/\" target=\"_blank\" rel=\"noopener\">Website<\/a><\/p>\n\n\n\n<p>TEJ Tool API is designed for users requiring diverse data types.
