PC上的股票交易软件的自动止损、自动下单等功能比较弱，不如期货交易软件。
自力更生，程序员都是自己打造工具。
根据IPO模型（Input 输入，Process处理，Output输出），为了方便自动化首先要获取当前交易软件上浏览的股票代码。
截图再OCR显然太麻烦，通过Winspy工具查看下交易软件自带功能的消息号（33780），大家记住这个号码！
下面在用AutoHotkey作为变成语言，发送这个消息号来获取当前浏览的股票代码。
;脚本功能：获取通达信软件上的股票代码
;测试环境：招商证券、中银国际提供的官方通达信客户端

;验证方式：在交易软件中按 热键 win+z#z::
SendMessage,0x111,33780,0,,ahk_class TdxW_MainFrame_Class
MsgBox %Clipboard%
return效果如下，简单一条SenMessage语句解决！后续可以利用这个代码去记录、去自动化下单、或者联动到其它交易软件中。
如有需求，可以联系我微信交流，欢迎打赏！
有朋友索要查看消息的ahk工具，代码如下（2021年2月25日更新，只显示当前鼠标下面菜单项的消息号）：
用法：下面代码存成独立ahk脚本，运行之。在想要查看消息的程序内，调出该软件的相关菜单，把鼠标移动到某个菜单项上，查看屏幕左上角的tooltip。
