I wrote customized software for personal use because what is available out there is not offering what I want exactly. I use them myself on a daily basis to monitor the markets. They are available on this blog.
The websites are updated at least once per day. Sometimes, the data source is broken and updates cannot be made.
I put my idle money with moomoo Cash Plus while waiting for investment opportunities because it offers above-average yield and can be withdrawn within days. If you are keen, please read my review and sign up if you like it.
