Action
Get Stock Previous Close Data
This tool retrieves the previous day's closing data for a specific stock symbol. it provides essential trading information including the opening price, highest price, lowest price, closing price, trading volume, and timestamp for the previous trading day. it complements other finage tools by offering detailed previous day data, which is useful for computing day-over-day change and informing daily trading analysis.
Why this helps
A changed signal on a message can reopen a discussion, but the supporting data may not be handy when the team returns to it.
- Connect a changed message signal to a concrete data refresh.
- Help a reopened discussion regain its market context.
- Avoid starting the lookup from scratch when a note is revisited.
Setup
Build it in a few focused steps.
- 1Connect Slack and Finage to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis to retrieve previous-close data when a chosen reaction is removed from a Slack message that names a stock.
- 3Select the Slack message reaction removed trigger and choose a channel for run reports.
- 4Test by removing the chosen reaction from a ticker-related message.
Questions about this workflow
When would reaction removal be useful?
It can signal that a message needs renewed attention, if your team uses the chosen reaction consistently that way.
Does this update the Slack message?
The configured Finage action retrieves previous-close data; the automation prompt should specify how Notis reports the result.
