BLIX Market Data Methodology

BLIX tracks CS2 item listings across supported marketplaces and turns that data into practical market signals: current prices, offer counts, wear-based ranges, marketplace availability, price history, and popularity indicators.

 

This methodology explains how BLIX collects, cleans, ranks, and displays market data for CS2 skins, knives, gloves, cases, stickers, agents, and other tradable items. It also explains what each metric means, what it does not mean, and how users should interpret the numbers shown on item pages.

BLIX market data is designed for comparison and research. It is not financial advice, investment advice, or a guarantee that a listed offer will remain available.

What BLIX Market Data Covers

BLIX item pages combine several types of information:

 

• current marketplace offers;

• lowest and highest tracked prices;

• price ranges by wear and version;

• active offer counts;

• marketplace coverage;

• price history;

• item metadata such as rarity, collection, container, float range, and available versions;

• popularity and liquidity signals where enough data is available.

 

For example, an AK-47 skin page may show the current lowest tracked offer, the number of active listings, the cheapest available wear, the collection it belongs to, whether StatTrak versions exist, and how its current price compares with recent history.

 

BLIX does not create, sell, or custody CS2 items. Marketplace availability, prices, fees, seller reputation, payment methods, and regional restrictions are controlled by the individual marketplaces.

Marketplace Sources Used by BLIX

BLIX tracks offers from supported CS2 marketplaces and trading platforms that provide enough structured listing data to compare item prices reliably.

 

A marketplace can be included in BLIX tracking when it provides at least the following:

 

• item name or market hash name;

• price;

• currency;

• item version, such as normal, StatTrak, or Souvenir where applicable;

• wear condition or float value where available;

• listing URL;

• listing availability status;

• marketplace identifier;

• timestamp of the latest listing update.

 

BLIX may exclude a marketplace from certain calculations if its data is incomplete, stale, duplicated, region-locked, or not comparable with the rest of the tracked market.

Example

If two marketplaces list AK-47 | Crane Flight (Field-Tested), BLIX can compare those listings only when both offers clearly refer to the same item version and wear. If one source does not identify wear or returns a stale unavailable listing, that offer may be shown separately, excluded from the calculated market price, or ignored until the data is refreshed.

How BLIX Normalizes Marketplace Prices

Marketplace data is normalized before it appears on BLIX.

 

The normalization process can include:

 

• converting prices to the display currency used on BLIX;

• removing unavailable or expired listings;

• deduplicating repeated offers from the same source;

• matching marketplace item names to the BLIX item database;

• separating normal, StatTrak, and Souvenir versions;

• separating wear conditions such as Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred;

• excluding listings with missing or invalid price data;

• flagging suspicious outliers for review.

 

BLIX tries to compare like with like. A normal AK-47 | Redline (Field-Tested) listing should not be mixed with a StatTrak listing, a Souvenir listing, or a different wear unless the page explicitly says that the metric covers all versions.

How BLIX Calculates the Current Price Range

The current price range on an item page is based on active tracked offers that pass basic data-quality checks.

 

BLIX commonly displays:

• Lowest tracked price: the lowest active offer found across supported marketplaces after filtering invalid listings.

• Highest tracked price: the highest active offer in the current comparable set.

• Offer count: the number of active listings used for the displayed item scope.

• Marketplace count: the number of unique marketplaces with at least one active comparable offer.

 

The displayed range is not a promise that every user can buy at the lowest price. An offer may become unavailable, require regional access, include marketplace fees, or change after BLIX last refreshed the data.

Example

If BLIX tracks 1,204 active offers for AWP | Asiimov across 24 marketplaces, and the lowest valid offer is $73.08 while the highest valid offer is $239.85, the page may display:

 

 

These values should always be shown together with a precise update time, such as Prices checked July 16, 2026 at 14:35 UTC.

How BLIX Calculates the Market Price

The lowest price is useful, but it can be unstable. A single underpriced listing, damaged data point, or unavailable offer can distort the market view.

 

For this reason, BLIX can use a market price estimate based on a cleaned group of comparable offers. The exact calculation may vary by item type, but the preferred approach is:

 

1. Start with active comparable offers for the same item, version, and wear.

2. Remove unavailable, duplicated, or invalid listings.

3. Exclude extreme outliers when they are far outside the normal marketplace range.

4. Calculate the median price or a trimmed average from the remaining offer set.

5. Display the lowest tracked offer separately from the calculated market price.

 

The market price is intended to answer a different question from the lowest offer.

 

Example

If one marketplace briefly lists a Field-Tested skin at $10 while most comparable offers are between $18 and $22, BLIX may still show the $10 offer as the lowest tracked offer. However, the market price should remain closer to the stable range if the $10 listing is an outlier or disappears quickly.

How BLIX Handles Wear, Float, StatTrak, and Souvenir Versions

Wear and float can change the price of a CS2 skin dramatically. BLIX separates wear-based data whenever enough marketplace information is available.

 

For weapon skins, BLIX can display prices by:

 

• Factory New;

• Minimal Wear;

• Field-Tested;

• Well-Worn;

• Battle-Scarred.

 

For each wear, BLIX may show:

 

• lowest tracked price;

• market price or median price;

• active offer count;

• cheapest marketplace;

• 24-hour, 7-day, 30-day, and 90-day movement where enough history exists.

 

StatTrak and Souvenir versions should be treated as separate market variants because they often trade at different price levels and have different demand patterns.

Example

For AK-47 | Crane Flight, BLIX may compare Field-Tested and Battle-Scarred offers separately:

 

 

This kind of comparison is more useful than a generic statement such as “this skin is affordable.” BLIX should explain the reason with numbers.

How BLIX Ranks Marketplace Offers

BLIX offer lists are designed to help users compare options quickly. Offers can be ranked by a combination of price, availability, marketplace quality, and sponsorship status.

 

The default ranking should prioritize:

 

1. active availability;

2. item match accuracy;

3. lowest comparable price;

4. marketplace reliability signals;

5. clear version and wear data;

6. update freshness.

 

Sponsored offers may be displayed on BLIX, but they should not change the calculated market price unless the methodology explicitly says so. Sponsored placement should be labeled clearly.

Lowest Trusted Offer

The Lowest Trusted Offer is the cheapest active offer that passes BLIX quality checks.

 

An offer should not qualify as the lowest trusted offer if:

 

• the listing is stale or unavailable;

• the item version is unclear;

• the wear or float does not match the page scope;

• the price is missing or invalid;

• the marketplace fails the minimum reliability threshold;

• the offer is sponsored and the block is specifically meant to show non-sponsored market data.

Example

If Marketplace A shows an item for $12.00 but the listing is stale, and Marketplace B shows the same item for $12.40 with confirmed availability, BLIX should use Marketplace B as the lowest trusted offer.

How BLIX Builds Price History

Price history is based on repeated snapshots of comparable offers over time.

 

BLIX can use the following values in historical charts:

• lowest tracked price;

• median price;

• market price estimate;

• active offer count;

• marketplace count;

• version and wear-specific price points where available.

 

For item pages, BLIX should identify whether a chart uses all versions, one version, or one specific wear. A chart for all AK-47 | Redline offers is not the same as a chart for AK-47 | Redline (Field-Tested).

Example

A 30-day price change should compare the same item scope at two different points in time: 

 

In this example, the 30-day change is +4.9%.

 

BLIX should avoid showing percentage changes when the historical scope is incomplete or when the earlier data point is missing.

How BLIX Calculates Popularity

BLIX popularity is a market activity signal, not a statement about in-game strength, visual quality, or investment potential. 

Popularity can be calculated as a 0-100 score using normalized marketplace signals. A plausible model is: 

 

The final score should be capped between 0 and 100

BLIX should not display popularity values above 100%. If the underlying calculation produces an invalid value, the popularity block should be hidden until the data is corrected.

Popularity Bands

Example

If a skin appears on 22 marketplaces, has thousands of active offers, and receives frequent fresh listings, it may receive a high popularity score. If another skin appears on only two marketplaces with a small number of stale offers, it should receive a lower score or no score if the data is too thin.

How BLIX Calculates Liquidity

Liquidity describes how easy it may be to compare, buy, or sell an item based on current market depth.

 

BLIX liquidity can use:

 

• active offer count;

• marketplace count;

• spread between the lowest offer and median price;

• recent listing freshness;

• recent sales or completed-trade data where available;

• number of comparable offers per wear or version.

 

A skin with many active offers across many marketplaces is usually easier to price than a rare item with only a few listings. However, high supply does not always mean strong demand. BLIX should treat liquidity as a market-depth signal, not a buy recommendation.

How BLIX Detects Outliers and Bad Data

Marketplace data can contain errors. BLIX may filter or flag data when:

 

• the price is zero, negative, missing, or impossible;

• the item name does not match the BLIX entity;

• the listing points to the wrong version;

• the marketplace returns duplicate listings;

• the offer disappears during refresh;

• the price is far outside the normal range for the item;

• the update timestamp is too old;

• the listing cannot be connected to a valid marketplace URL.

 

When BLIX does not have enough reliable data, the page should show a clear message instead of forcing a misleading metric.

Example

Instead of showing 0.00% drop probability or 118128% popularity, BLIX should hide the block and display:

 

Not enough reliable market data is available for this metric yet.

How BLIX Handles Item Metadata

BLIX item metadata is used to connect market data with the correct CS2 entity.

 

Metadata can include:

 

• item name;

• weapon or item type;

• rarity;

• collection;

• container;

• release date;

• finish style;

• available wear range;

• minimum and maximum float;

• available versions;

• creator information where available.

 

This metadata should be separated from market calculations. For example, rarity is a property of the item, while market price is a current marketplace signal.

How BLIX Updates Market Data

BLIX item pages should display the exact time of the latest successful data refresh.

 

The preferred format is:

 

Prices checked July 16, 2026 at 14:35 UTC

 

If different data blocks update at different times, BLIX should label them separately:

 

• offers updated at a specific time;

• price history updated at a specific time;

• item metadata last reviewed on a specific date;

• methodology last updated on a specific date.

 

Relative freshness labels such as updated recently are less useful because they do not tell users or search engines when the data was actually checked.

How BLIX Uses Editorial Review

Automated market data can explain what is happening, but editorial review helps explain why it matters.

 

BLIX may add editorial notes to high-value or high-traffic item pages when a skin has:

 

• unusual price movement;

• limited marketplace availability;

• large differences between wears;

• unusual StatTrak or Souvenir pricing;

• strong collector interest;

• major changes after a CS2 update;

• newly added marketplace data.

 

Editorial notes should be reviewed by a human editor or data reviewer and should include a last reviewed date.

Example

Instead of writing:

 

Battle-Scarred is the best value.

 

BLIX should write:

 

Battle-Scarred is currently the cheapest entry point because it has the lowest median price and the highest number of active offers among tracked wears. Choose Field-Tested instead if you prefer a cleaner look and the price premium is acceptable.

How BLIX Presents Sponsored Offers and Affiliate Links

Some marketplace links on BLIX may be sponsored or affiliate links. Sponsored or affiliate relationships do not mean that BLIX owns the marketplace or controls the final transaction.

 

BLIX should disclose:

 

• when an offer is sponsored;

• whether sponsored placement affects offer sorting;

• whether affiliate links may generate commission;

• whether commission changes the price paid by the user;

• whether sponsored offers are excluded from calculated market price metrics.

 

For trust, calculated metrics such as market price, median price, popularity, liquidity, and price history should be based on data rules rather than advertising relationships.

How Users Should Interpret BLIX Market Data

BLIX market data is best used for comparison.

 

Users can use BLIX to answer questions such as:

 

• Which marketplaces currently list this item?

• What is the lowest tracked offer?

• How wide is the price range?

• Which wear is currently cheapest?

• How many offers are active?

• Is the item broadly available or thinly listed?

• Has the market price changed recently?

 

Users should still check the final marketplace page before buying. Final price, fees, availability, seller reputation, regional access, and payment options may differ from the BLIX snapshot.

Limitations of BLIX Market Data

BLIX market data has several limitations:

 

• offers can change after the latest refresh;

• marketplaces may update or remove listings without notice;

• fees and taxes may not be included in every displayed price;

• regional restrictions can affect availability;

• low-supply items can have unstable prices;

• rare versions may not have enough data for reliable trends;

• historical charts depend on consistent snapshots over time.

 

When data is missing or unreliable, BLIX should avoid publishing forced conclusions. A missing metric is better than a misleading metric.

Corrections and Data Feedback

If users notice incorrect item data, stale prices, broken marketplace links, or mismatched item versions, they can report the issue to BLIX.

 

A useful report should include:

 

• the BLIX page URL;

• the item name;

• the marketplace URL;

• the incorrect value;

• the expected value;

• a screenshot or timestamp if available.

 

BLIX should review reported data issues and update affected pages when the correction is confirmed.

Methodology Change Log

BLIX should update this methodology when it changes: 

• marketplace coverage;

• price normalization rules;

• offer ranking rules;

• popularity or liquidity formulas;

• outlier filters;

• refresh frequency;

• sponsored offer treatment;

• item metadata sources.

 

Each methodology update should include a date and a short explanation of what changed.
