使用 AWS Lambda 搭配 EventBridge (CloudWatch Event) 定時發送每日資料至 Telegram

1. MoneyDJ

   基金資料, 每日更新時間約為 9:30 ~ 10:00 之間

   EventBridge Schedule expression: cron(0 2 ? * TUE-SAT *)

2. Yahoo Finance

   美股資料, 每日收盤時間為 04:00 (UTC+8), 夏令 05:00 (UTC+8)

   EventBridge Schedule expression: cron(30 21 ? * MON-FRI *)

要把 package 都包進 zip, 再上傳到 AWS Lambda

另外一個做法是把 package 包成 zip, 放到 layer 內, 如果是 python, 要在 zip 內新增一個 python 資料夾

參考以下連結的 Include library dependencies in a layer
