Market news for an F&O trader is a volume problem, not a scarcity problem. One announcement at ten in the morning is fifteen articles by eleven, each a rewrite of the same filing, and a raw aggregator hands you all fifteen. This feed collapses coverage of one underlying story into a single entry.
What you scroll is therefore a count of distinct events rather than a count of articles published. The difference shows up most on busy days. A session with one large regulatory announcement and a session with twenty separate company disclosures produce a similar quantity of text in a raw feed and look nothing alike here, which is the only property of a news feed that actually saves time.
Collapsing is done on the story rather than on the source. A wire report and the papers that rewrite it become one line, and that line is the one that appeared first, because for a position already on the book the time a story broke matters and the time an outlet got around to it does not.
The feed leans toward the events that reprice options rather than the ones that move a stock a per cent:
De-duplication is a judgement about whether two headlines are the same story, and it is wrong in both directions occasionally: a genuine follow-up carrying new information can be folded into the original entry, and two separate announcements about one company minutes apart can be merged. When something touches a position you are carrying, open the entry rather than trusting the single line.
The second limit is that a feed is not an edge. By the time an event is a headline the option chain has usually already moved, and the participants who repriced it were not reading this. A feed is good for explaining a move you can already see on the implied-volatility and straddle charts, and for knowing what is scheduled before you carry a position through it. Nothing here is filtered or scored for sentiment, and none of it is advice.
Because most outlets are rewriting one primary source, usually an exchange filing or a wire report, within the same hour. A raw aggregator counts articles, so one event fills the screen. This feed groups those rewrites into a single entry, which turns the list back into a list of things that happened rather than a list of things that were published.
Scheduled and structural events, mostly: results and result dates, corporate actions, exchange and regulatory notices, and index rebalances. These change either the contract itself or the uncertainty inside its remaining life, so implied volatility has to respond. Commentary and narrative pieces can move a stock a per cent without changing what the option market charges at all.
It updates through the trading session as stories break, and it keeps running outside market hours, since filings and regulatory notices do not stop at 3:30. Each entry carries its own timestamp from when the story first appeared, so you can tell a fresh development from one that has been sitting there since the morning.
Realistically, no. By the time something is a headline the option chain has usually repriced, and whoever moved it was not waiting for an article. A feed is useful for the opposite job: explaining a move you have already seen in implied volatility, and knowing what is scheduled before you carry a position into it.
It happens occasionally, because grouping is a judgement on headline and body text rather than a fact the source supplies. Two announcements about the same company minutes apart are the usual case. Open the entry to see the individual reports underneath it whenever the story touches a position you are actually carrying.
