Market data and calculator methodology
Every useful number needs a definition, a time, and a source. This is how the current charts, market reads, and tools turn inputs into what you see.
Latest prices, changes and market sessions
The headline uses the newest timestamped price available, with points and percentage change from that same provider. We do not mix a current quote with another provider’s previous close. Crypto comparisons labeled 24h use a rolling 24-hour reference. If the newest valid observation is a daily close, it is labeled accordingly.
The market change beside a daily series is (latest completed close ÷ previous completed close − 1) × 100. The observation date belongs to the market's local trading day. It is not the time the page was downloaded.
For supported calendars, a close remains the latest completed session through weekends, listed holidays, and the following session until that session closes. For example, Nifty's 1 October 2026 close remains the latest through the 2 October holiday and 3–4 October weekend. Three elapsed days do not by themselves make that close outdated.
The reviewed calendar coverage currently includes NYSE 2026–2027 and NSE 2026. Other venues use regular-session context without claiming complete holiday verification. Dates outside reviewed coverage are treated as unverified. Crypto daily candles use completed UTC days.
Reading and inspecting candles
A candle records its open, highest price, lowest price, and close. Its direction compares its own close with its open. This differs from the daily percentage, which compares successive closes. A rising candle can therefore coexist with a negative day-over-day return.
Choose the candle interval separately from the date range. One-minute candles come from the provider; 5-minute, 15-minute, and hourly bars combine contiguous completed minutes. The open is the first open, the close is the last close, highs and lows take their extrema, and volume is summed. Missing minutes are not invented. Incomplete buckets are omitted.
Cash-market buckets are anchored to the venue's regular opening time; crypto buckets use UTC midnight. The date range ends on the latest available observation. Minute history is collected on a separate schedule, currently every 60 seconds, so candle history and quote updates can have different timestamps.
Point or tap a candle to inspect it. When the chart has keyboard focus, use the arrow keys, Home, or End. The optional “View values” table exposes exact figures without making everyone read a table.
Sources, units, and collection
Current prices use Upstox, Coinbase Exchange and Yahoo Finance, with the provider and observation time available in Price details. Yahoo prices may be delayed. A small last-updated cue appears when an observation is over 15 minutes old during that instrument's scheduled open session. Closed sessions do not trigger that cue; their observation times remain available in the disclosure. Session schedules cannot detect unscheduled trading halts.
NSE timings are collected from Upstox and retained with quotes. Other cash venues use reviewed exchange calendars including holidays, daylight-saving time and lunch breaks; crypto trades continuously. Commodity futures use the provider trading period bounded by the standard CME weekly session and daily maintenance break. Exceptional holiday hours can differ.
WTI crude oil, Henry Hub gas and gold futures are separate rolling-contract quotes from Yahoo Finance. The current provider contract name is in Price details. These are not spot prices, and a continuous history may cross contract rolls. EIA spot observations below remain dated daily publications and can be several days behind trading prices.
The Data sources & methodology disclosure lists each series and provider. Index and crypto feeds can differ in coverage, timestamp convention, and available history. If a feed is unavailable, we do not replace it with an invented price. A chart's availability does not grant permission to redistribute its underlying data.
Macro observations come from the U.S. Energy Information Administration for WTI oil and Henry Hub gas, the U.S. Treasury for 10-year par yields, and the European Central Bank for currency reference rates. Prices use their stated units; yield changes are in basis points. ECB reference rates are dated reference observations, not executable FX quotes.
A shared collector validates provider responses and stores results independently of readers. Browser requests read a shared API response, not a fresh provider request per visitor. Fetch time, observation time, and a provider's publication lag are different. Invalid high/low ranges are rejected rather than quietly repaired.
The observed futures move
Where both observations exist, the displayed move is (futures observation ÷ the same futures series at the last cash close − 1) × 100. The reference is the nearest eligible one-minute observation within five minutes of the cash close; the actual timestamp and offset are retained.
This is a movement in the futures series, not a guaranteed cash-opening gap. Contract basis, rolls, continuous-series construction, liquidity, and timestamp conventions can affect it. Dow futures are not Nasdaq futures, and a cash Nasdaq-100 series cannot stand in for a futures quote.
Older futures observations carry their observation time and are described as an earlier read. The cash market being closed does not prove a futures quote is current, because the instruments have different trading sessions. If the reference window is missing, we withhold the calculation.
The country direction reading
The country panel describes a conditional setup for the current cash session, or the next session when closed. Crypto uses a next-24-hour horizon. It is a transparent rule-based reading of stored observations, not a calibrated probability, trade instruction or validated prediction.
For a positive or negative setup, at least two selected external benchmarks must agree in sign. During an open local session, a fresh local benchmark must confirm that sign. Mixed signs or an unchanged local benchmark produce a two-way reading. Missing current evidence produces an awaiting-data state. India watches the S&P 500, Nikkei and Hang Seng; the US watches DAX, FTSE and Nikkei. The exact available inputs and dates are in the panel disclosure.
Fresh rising oil tempers a positive India setup, and falling oil tempers a negative one. A recent rise in US yields similarly tempers positive US or crypto readings, with the reverse for falling yields. These are qualitative economic channels, not fitted coefficients. Other country channels remain explanatory context. Sector developments and policy surprises are not captured by this simple rule.
Open-market observations older than 15 minutes are excluded. Closed-market evidence must belong to the latest completed session. US yield context must be a published observation within four days; it is not an intraday yield. The reading can change as data arrives. No forecast success rate, numerical confidence or empirical advantage is claimed.
What we do not claim from the cues
Oil, gas, yields, currency moves, crypto, and overseas sessions can provide context. They do not mechanically determine an index's next move. We do not turn hand-picked sector weights into a public probability or fabricate contribution bars to explain a price change.
A meaningful model needs point-in-time inputs and evaluation on later sessions that were not used to fit it. Directional accuracy alone can be misleading when a market rises more often than it falls. Calibration, probability error, and simple reference models help reveal whether a model adds useful information.
Observed price changes and explanatory context are distinct from numerical forecasts. Any published probability must identify its target, cutoff, model version, and independently assessed track record. The observed market read should not be interpreted as a probability of making a profit.
Calculator assumptions
Compound growth applies the stated annual rate through monthly compounding and assumes contributions at the end of each month. The result separates contributions from modeled growth. A constant assumed return is not a prediction, and fees, tax, and inflation are excluded unless explicitly included.
The loan tool uses a level-payment amortization schedule. Monthly rate equals the stated annual percentage divided by 12. At a zero rate, payment is principal divided by the number of months; otherwise payment is P × r ÷ (1 − (1 + r)^(−n)). Product fees, changing rates, and lender-specific daily interest are not included.
Emergency runway is available cash divided by monthly spending; a target reserve is monthly spending multiplied by the selected number of months. Net worth is the stated assets less the stated liabilities. These simple views do not appraise assets or verify debts.
Display currencies are labels for the amounts you enter. Selecting INR uses Indian digit grouping, but does not convert a USD amount into rupees. Check the full tool's assumptions before comparing a result with a real product.
