/**
* Plays one or more notes through Midi. If you find yourself wanting to use lots of individual
* sound files for a scenario, such as emulating an instrument for example, you may find using
* midi a better choice. It has several advantages over using lots of wav files:
* <ul>
* <li>It takes up far less space, so less disk space is used and loading times are reduced</li>
* <li>You can switch between instruments really easily if you wish</li>
* <li>You can adjust things like the length of time notes are held for really easily</li>
* <li>You can generally manipulate the details of midi notes far more easily than you can with actual sound files</li>
* <li>If you really want to be clever, you can add pitch bend, adjust how quickly notes are played and more!</li>
* </ul>
* However, Midi is not always suited to the task - the sounds aren't always the same on each
* computer (since they're generated through the sound card and not in advance) and the quality
* won't be as good as a recorded sound. If you're looking for special effects, a backing track
* or in game sounds then chances are you'll be better off using normal sound files.

/*
* DawnTrades is a free and open-source stock charting Java program
* that is intended to assist with trading publicly available common stock.
*
* Java and the Java Library xChart is utilized for the creation of DawnTrades
* due to the relative ease and convenience of making fast programs with graphs/charts.
*
* Currently, the development of this working prototype does not have all the features
* that are going to be present in the final non-prototype build.
* All features, User Interfaces (U.I.), and methodologies are subject to change
* during the development and improvement of this and future working prototypes.
*
* DawnTrades currently has:
*
* A simple static graph that shows the stock price of a single stock ticker.
* Inserting stock data via .csv file.
* Stock indicators.
* Technical Analysis integration.
*
* For long time goals:
*
* Using Funadamental Analysis combined with Technical Analysis
* to provide accurate predictions that can be displayed on charts.
* Be able to predict time to buy and sell for
* 1 day, 5 days, 1 week, 1 month, 3 months, 6 months, 1 year, 2 years, 5 years, 10 years, and lifetime of stock.
* Clean, simple, easy to understand User Interface (U.I.)
* Fast - Trades today happen between milliseconds to nanoseconds.
* Should speed be balanced by accuracy, or should speed be prioritized over accuracy?
*
* Extra features that could be added:
* Customizations of U.I.
* Customization of trading strategies.
*
* Derived and modified from a simple program given by ChatGPT.

| WeiJian123-tech/DawnTrades | Main.java | 567 | /*
* DawnTrades is a free and open-source stock charting Java program
* that is intended to assist with trading publicly available common stock.
*
* Java and the Java Library xChart is utilized for the creation of DawnTrades
* due to the relative ease and convenience of making fast programs with graphs/charts.
*
* Currently, the development of this working prototype does not have all the features
* that are going to be present in the final non-prototype build.
* All features, User Interfaces (U.I.), and methodologies are subject to change
* during the development and improvement of this and future working prototypes.
*
* DawnTrades currently has:
*
* A simple static graph that shows the stock price of a single stock ticker.
* Inserting stock data via .csv file.
* Stock indicators.
* Technical Analysis integration.
*
* For long time goals:
*
* Using Funadamental Analysis combined with Technical Analysis
* to provide accurate predictions that can be displayed on charts.
* Be able to predict time to buy and sell for
* 1 day, 5 days, 1 week, 1 month, 3 months, 6 months, 1 year, 2 years, 5 years, 10 years, and lifetime of stock.
* Clean, simple, easy to understand User Interface (U.I.)
* Fast - Trades today happen between milliseconds to nanoseconds.
* Should speed be balanced by accuracy, or should speed be prioritized over accuracy?
*
* Extra features that could be added:
* Customizations of U.I.
* Customization of trading strategies.
*
* Derived and modified from a simple program given by ChatGPT.
*
* Java Version: Java 8+
*
* Java Library: XChart
