Hello, we have read your project requirement; something we have doubt about, how can the user of your site get access to the archive of announcements? from what we have understood, the third-party feeds provide daily announcements, or announcements from 1 previous trading day. we believe we can do this job, but we need to make sure the third-party feeds provide enough info. fyi, we have +15 years of experience in creating web applications. Looking forward to hear from you. Thank you
