完全使用TRAE和AI 开发一款完整的应用----第一周

虽然也在工作使用使用ai 补全代码或者完善代码，但还是没有完全使用ai 做一款应用，不依赖手工编程、不依赖人查找资料

所以决定自己写一个应用玩玩，感受一下全完使用ai开发一款应用的乐趣，跟上时代发展的步伐

不得不说以前写玩具项目挺枯燥，现在用ai写还是挺有意思的

应用的需求：

使用ai 分析 k线，并进行点评，让天底下的韭菜没有看不懂的k线，让ai进行cosplay 扮演各路专家进行点评，这不是一款应用这是一款ai驱动的综艺节目

考虑我国复杂的金融监管环境，对股票分析限制非常多，所以对美股和港股还有web3 领域的token 进行分析

下面是项目和代码文件

主要是一个图表组件TradingChart.tsx和首页 page.tsx
