Session Charts

One trading day of one stock, ETF or index, as a line of percent change from an anchor against minutes from that anchor. The anchor is the previous close by default, so the line starts at the open with the overnight gap already on it; it can be the open instead, or a clock time such as the 2:00pm Fed statement. Up to eight sessions go on one chart, each in its own colour, which is how you compare the day after five different earnings reports or the last eight CPI mornings.

Five-minute bars for the last two months and hourly bars for the last two years, from Yahoo Finance. Older sessions are drawn as a straight line from the open to the close, and the legend says so. The chart is built for the shape of a day, not for trading off: it is not a replacement for a live charting platform.

The first regular session traded with the results known, the same rule the earnings history tool uses. For a company that reports after the close that is the next day; for one that reports before the open it is the report day itself. The earnings tab can also chart the report day, which for an after-close print is the run-up into it.

From the site’s own verified calendars: the economic calendar for every CPI, PPI and jobs release with its S&P 500 move, and the Fed meeting calendar for every FOMC decision day. None of them is scraped at request time.

Yes. The address bar always holds the chart on screen, symbol, dates, anchor and all, so copying the URL shares exactly that chart. The share bar also copies or downloads the chart as a watermarked PNG, and a shared link previews as the chart itself.

Prices are Yahoo Finance’s chart data, fetched per session at the finest granularity still available for a day of that age: 5-minute bars inside two months, hourly bars inside two years, the daily open and close beyond that. Each point is the last price of its bar, stamped at the bar’s end, and the 9:30am point is the session’s official open. The previous close is the prior session’s daily close. Extended-hours prints are thin and shown only when switched on. A session still trading refreshes every minute and is marked live; everything else is fixed once the day has closed. Earnings dates and timings come from the same feed and rule as the earnings history tool; macro dates from the economic calendar and the Fed meeting calendar. Past sessions describe what happened; they are not a forecast.
