Data & Forecast Methodology

How the source reference becomes the displayed data, indicators and planning scenarios.

Market data + short-term model
1

One reference across every page

Quote, history, forecast and calculators use the same Yahoo Finance chart snapshot. Source observation time and automated check time are shown separately. Price changes use the previous completed observation. Bond moves are basis points; index values are points.

2

Source boundaries

Yahoo Finance supplies the named instrument reference and daily OHLC history. No placeholder catalogue prices, synthetic candles, or fabricated fundamentals are used.

3

Short-term statistical model

25%-shrunk 60/40 blend of 30/90-session mean log-return drift with a model-implied central 80% lognormal interval from 30-session realized volatility; constant-volatility assumption, not empirically calibrated coverage Intervals are not calibrated empirical coverage; jumps, fat tails and parameter uncertainty are excluded.

4

Signals and refresh

Indicators use completed daily observations and require 200 samples. Composite = (Buy − Sell) / rule count: Strong Buy above 0.55; Buy above 0.15; Neutral above −0.15; Sell above −0.55; otherwise Strong Sell. Each browser checks every 60 seconds; provider snapshots are cached for up to five minutes. Failed refreshes are visibly marked.

Long-term scenarios + controls
5

One scenario anchor

Every planning band uses the same timestamped reference displayed above. Changing the annual assumption updates the scenario chart, yearly bands and regular-contribution calculations.

6

Explicit planning assumptions

Lower and upper paths apply the selected annual change in opposite directions. The base path keeps the reference unchanged. These paths have no assigned probabilities and are separate from the short-term statistical model.

7

Market-specific interpretation

Prices use the instrument’s quoted units; indices use points and yield moves use basis points. Fees, taxes and distributions are excluded. A yield path cannot estimate a bond investment return.

Read as a range: short-term estimates and long-term planning scenarios can fall outside every displayed band. Source gaps and unsupported calculations are withheld.

How much history is available?

How are changes and conversions calculated?

Price changes compare observed reference values. Yield moves use basis points. Conversion amounts use the same timestamped source rate; spreads, fees and distributions are excluded.
