Methodology content updated 2 weeks ago

Source and timestamp

Live data includes a reference source or its latest update time.

Separate data from interpretation

Raw values, calculations and explanations remain distinct layers.

State the limitations

Missing data must lower confidence rather than be replaced by guesses.

Each tool uses its own method

Open the data center

One shared process

From original source to the screen

Each product has a different formula, but all pass through these five checks.

01
Collect
Receive data from APIs, exchanges, official documents or suitable public sources.
02
Normalize
Align units, timestamps, asset names and statuses into one format.
03
Calculate
Apply a versioned method; missing data lowers coverage or blocks a conclusion.
04
Check
Review freshness, valid ranges, sources and conflicts before display.
05
Publish
Show the result with its update time, interpretation and limitations.

Do not interpret every number the same way

These four results answer four different questions.

Radar score 0–100

Describes whether market conditions look weak, balanced or selectively strong.

It is not the probability of a price rise or an order to trade.

Fit score 0–10

Compares an option with the needs and criteria you selected.

It does not mean absolute safety or licensing in Vietnam.

Alert level Low → very high

Prioritizes signals to check before connecting a wallet or sending funds.

No alert found never guarantees that an asset is safe.

Strategy result Measured in R

Records whether a setup hit targets, broke even or reached its stop.

It evaluates the method, not the performance of a user account.

Source priority

Which sources come first?

The right source depends on the question, but original data and official documents take priority.

Direct market data

Exchange APIs, prices, liquidity and indicators from providers with clear update schedules.

Official sources

Exchange notices, project documents, regulators and public records take priority when available.

Coin4VN explanation layer

Editors and AI may explain existing data; neither is treated as the original source of a fact.

Frequently asked questions

When should you trust a result?

Four short answers before using data in a real decision.

Does a high score mean I should buy now?

No. A score describes conditions or fit from its inputs. Review the contributing factors, update time and asset-specific risks first.

Why can a price or indicator differ from another website?

Sources, trading pairs, snapshot times and aggregation methods differ. Coin4VN shows its source and timestamp so you can compare them.

Does AI decide scores or facts?

No. Normalized data and formulas create results. AI may help explain or review wording, but it cannot replace the source or calculation.

What happens when data is delayed or missing?

The result must lose coverage, show that an update is needed or withhold a conclusion. Coin4VN does not invent values to fill the interface.
