What these charts show, and what they leave out
Every bar is an end-of-day bar from Databento’s consolidated US equities summary, split-adjusted, about two years of them up to the last published session. Studies are computed in your browser from those same bars, over the whole history, so a 200-day average is a real value at the left edge of a one-year view. Each study carries its settings in its name, because a study is a measurement with parameters.
What is missing is missing on purpose. There are no intraday bars, live quotes, Level 2 or time and sales: those need data we do not show publicly, and a session VWAP needs intraday prints, which is why the VWAP here is a moving one built from daily bars. Oscillators carry a neutral midline and no 70/30-style bands, which would invite an overbought or oversold reading this page does not make. Nothing on the page picks a stock for you: the movers list is the last session’s measured moves, ranked, and the marks are records with their dates, not calls.
Questions
Are these charts live?
No. Every bar is an end-of-day bar: one per trading session, published after the close. There are no intraday bars, live quotes or order book here, and every chart says so under it. The newest bar is the last session our data provider has published.
How far back does the price history go?
To 1 July 2024, when the consolidated dataset we license starts: the All range shows everything since then, and 2Y shows the last two years. There is no 5Y view to offer. Prices are split-adjusted, so a 10-for-1 split does not draw a cliff on the chart.
Which timeframes are there?
Daily, weekly and monthly bars, over a month up to everything on file, picked from a list laid out the way trading terminals lay theirs out: 6 M : 1D is six months of daily bars, 2 Y : W two years of weekly ones. Star a timeframe to put it on the toolbar, or add any range with any bar under Customize list. A weekly or monthly bar is built from the daily bars: the first open, the high and the low, the last close and the summed volume, and the newest one is the week or month so far. Intraday bars, from 1-minute to 4-hour, are not available: showing them publicly needs data rights we do not have yet.
Which studies are there?
Twenty-seven, each with its settings in its name and editable: simple, exponential and weighted moving averages, a moving VWAP from daily bars, Bollinger, Keltner and Donchian channels, Parabolic SAR, Ichimoku, classic pivot points, Darvas boxes, ADX, RSI, MACD, stochastic, Williams %R, CCI, momentum, rate of change, PPO, TRIX, the awesome oscillator, a volume average, money flow, on-balance volume, the accumulation/distribution line and average true range. Each study can go on every chart or on one. Every formula is printed in the studies menu, and none labels a reading as overbought, oversold or a reason to trade.
What can I draw?
Trend lines, rays, extended lines, arrows, horizontal lines and rays, vertical lines, parallel channels, rectangles, ellipses, Fibonacci retracements, a measure tool and text notes. Lines and boxes report what they span: the price change, the percent change, the sessions and the calendar days. Click a drawing to select it, drag it or its points to move them, Delete removes it, and Ctrl+Z and Ctrl+Y undo and redo. A magnet option snaps points to the bar’s open, high, low or close.
What are the marks on the chart?
Records, dated by the day they became public. E marks an 8-K reporting results (Item 2.02), Q a 10-Q and K a 10-K, 20-F or 40-F, from the company’s own SEC submissions file; grey dots are its other 8-Ks. I+ and I- are insiders’ open-market purchases and sales from Form 4s of the last 180 days. C+ and C- are congressional stock trades, on the day they were disclosed. Split marks a split found in the bars, and H a trading halt from our halt archive, which only reaches back to the day it began recording. Hover a session and the legend lists each record with a link to it.
Where are my drawings and layouts kept?
Signed out, in this browser: drawings per ticker, named layouts, notes and studies. Signed in, they are also kept with your account and follow you to every device you sign in on; edits made on two devices are merged, so neither erases the other. The Layouts menu can also export all of it to one file. A link carries the tickers, the number of charts and the range, so Copy link reopens the same charts anywhere; drawings stay with you.
One company at a time, with its filings, ownership and calculators: the company workspace. The whole market for one session: movers, trading halts and the SPY holdings map. Educational information, not investment advice.
