Measuring how tight or wide a stock's last five days are, against its own history.
Some weeks a stock barely moves. Other weeks it swings from one extreme to the other. The Weekly Range tool measures how far a stock has traveled over its last five trading days and, more usefully, whether that is normal for the stock.
A range on its own is hard to read. A 2 percent five-day range is a very quiet week for a fast-moving small cap and a wild one for a steady blue chip. So the tool never judges a range by an absolute number. It compares this week only against the same stock’s own past.
The column labeled Tighter Than Its History does exactly that. It ranks today’s five-day range against every five-day range that stock has made, reaching back as far as 20 years of daily prices where the stock has traded that long. If today’s range is narrower than 90 percent of those past ranges, the stock is having one of its quietest weeks on record. If it is wider than most of them, the week has been unusually turbulent for that name.
Next to it, the Typical 5-Day Range column shows the median five-day range across that stock’s whole history, the middle of its normal. Reading today’s range against its typical range tells you at a glance whether this week is calm, ordinary, or stretched for that specific stock.
The Range Read column turns that percentile into plain English. It runs from Extremely Tight and Unusually Tight at the calm end, through Tighter Than Usual, Typical Range, and Wider Than Usual in the middle, to Unusually Wide and Extremely Wide at the turbulent end. Green marks the tight readings, red marks the wide ones, and the middle stays neutral.
The rest of the table answers the natural follow-up question: after weeks that looked like this one, what tended to happen next? The tool finds the past days whose five-day range was closest to today’s, measured on that same percentile scale, and gathers around fifty or more of the nearest matches into one group. A tight day is compared with the stock’s other tight days, and a wide day with its other wide days, so the odds you see are drawn from setups that actually resemble today’s.
For that group, the tool reports the next-day and next-week columns: the average up move, the average down move, and how often the stock closed green versus red by each date. Those are base rates drawn from history rather than forecasts of what comes next.
A quiet week is not a promise of anything. Sometimes a narrow range gives way to more of the same calm, sometimes to a larger move in either direction. The tool does not take a side. It shows how often each outcome actually occurred, up and down, and leaves the read to you.
Type any symbol and the tool opens a full breakdown for that stock: a projected price range over the weeks ahead built from those similar days, a probability graph for any move size you choose, and a complete log of every past week that resembled this one with the moves that followed. On the landing table, the default view sorts every stock by its tightest weeks first, so the names trading in their narrowest ranges rise to the top.
The high-to-low span of the last five sessions, shown as a percent of the low and in dollars. One number for how much ground the stock covered this week.
Where this week’s range sits against every past five-day range the same stock has made. A green meter marks an unusually tight week, red marks an unusually wide one.
A plain-English label from Extremely Tight to Extremely Wide, so you can read the week at a glance without reading the percentile.
For the past weeks most like this one, the next-day and next-week odds and the average up and down moves. The base rates after similar stretches, both directions.
The landing table opens sorted by the tightest weeks first. Scan the top to find the stocks trading in their narrowest five-day ranges relative to their own history.
Type a ticker and read its percentile. A range that looks dramatic on the chart may sit right in the middle of that stock’s normal, while a modest-looking week can be one of its quietest ever.
Use the forward columns and the similar-days log to see how often comparable weeks were followed by green versus red, and the average size of each move. The tool shows the history and leaves the read to you.
