# How fresh is the data?

> Where each feed comes from and what its lag looks like.

Different parts of auramarkets pull from different sources. Here's what's fast, what's slow, and what's planned.

## Equity prices and indices

**Source:** yfinance (Yahoo Finance free feed).

**Lag:** 15–20 minutes during US market hours. End-of-day close is the close (not delayed).

**Why:** real-time direct feeds cost meaningful money. The current build uses free feeds; the plan is to migrate to paid near-real-time feeds once the site is more bootstrapped.

## Treasury yields

**Source:** Primary is CNBC's quote endpoint (added in the most recent build); fallback is yfinance.

**Lag:** Roughly real-time during US market hours via CNBC. Daily close otherwise.

**Why:** rates are too important to leave on a 20-minute delay. CNBC's free endpoint provides effectively-live yields.

## Volatility tickers (VIX, MOVE, SKEW, etc.)

**Source:** yfinance.

**Lag:** 15–20 minutes. Same as equities.

## Quant score and Daily Recap

**Source:** computed in-house.

**Cadence:** quant score updates **every 5 minutes** during market hours (8 AM – 6 PM ET, weekdays). The score is logged to a timeline regardless of user traffic, so the [day's arc bar](/concepts/days-arc-bar) fills end-to-end even if no one is on the page.

The Daily Recap is generated automatically at **4:30 PM ET** on weekdays.

## Market Pulse

* Tiles refresh every 5 minutes
* AI Briefing refreshes every \~15 minutes
* Events / Calls update as picked up from feeds (within minutes)

## Research feed

**Source:** Substack, X, YouTube ingestion pipelines.

**Cadence:** daily ingest, runs overnight. Items appear the next morning.

## Portfolio holdings

**Source:** Plaid (read-only).

**Cadence:** daily auto-refresh. Manual refresh button available in the controls.

## Off-hours behavior

Outside market hours and on weekends, you'll see the last cached values. The site doesn't burn API calls fetching nothing. Daily Recap shows the most recent recap; arc bar fills its full range based on last session.

## Coming improvements

* Paid near-real-time equity feeds (planned, no date)
* Paid options chains for richer vol calculations (under consideration)
* Live Market Pulse refresh at sub-5-minute intervals (depends on data feed upgrade)
