摘要：# -*- coding: utf-8 -*-# @Author : 小红牛#, messageboxclass StockTradingGUI: def __init__(self, root): self.root = root self.root.tit
主要设计说明：该版本提供了接近专业交易软件的界面体验，同时保持了代码的简洁性和可扩展性，若要用于股票交易模拟教学或个人投资练习，还需要接入真实的股票交易数据，以下源码中的数据虚拟模拟随机生成的数据。
1.界面布局重构：将行情和持仓并排显示在面板中，持仓使用带标题的LabelFrame包裹，持仓Treeview添加汇总行并设置不同背景色。
2.持仓信息实时显示：移除单独的"显示持仓"按钮，持仓信息与行情同步刷新（每3秒），自动颜色标记盈利（红色）/亏损（绿色），增加了持仓市值的实时计算和显示，自动计算并显示总浮动盈亏。
3.显示优化：所有面板使用LabelFrame添加标题，交易记录显示框添加标题，持仓表格自动计算并显示总盈亏。
4.自动更新机制：持仓数据随价格波动实时更新，买卖操作后立即刷新持仓显示，汇总行使用不同背景色突出显示。
5.新界面特点：实时行情和持仓信息并排显示，持仓信息包含详细成本和盈亏计算，自动汇总显示总浮动盈亏，所有数据实时同步更新，界面布局更加紧凑合理。
6.操作说明：初始默认资金500万，可自由修改。持仓信息会随价格波动自动更新，买卖操作后持仓立即刷新，总盈亏显示在持仓表格底部，其他操作方式保持不变。
