How to Get BUFF Gamma Doppler Price History

cs2.sh records BUFF Gamma Doppler history for Phase 1 through Phase 4 and Emerald separately. Dedicated BUFF history adds phase-specific float buckets and average-ask OHLC from May 19, 2026.

Emerald is a distinct variant, not a fifth ordinary phase. Its price and market depth should remain separate from Phase 1 through Phase 4 throughout a history analysis.

Two BUFF Gamma Doppler history views#

POST /v1/prices/history provides per-source variant OHLC for BUFF alongside the other marketplaces. That series begins December 24, 2025 and supports 5m, 30m, 1h, and 1d intervals. BUFF points include ask and bid OHLC, last-observed ask_volume and bid_volume, sample_count, and the real open_time and close_time.

POST /v1/market/buff/history provides the more detailed BUFF range model from May 19, 2026:

• Every variant has a base bucket for its phase-wide market.
• Each phase can have narrower float buckets with independent prices.
• ask, avg_ask, and bid each receive OHLC fields.
• ask_volume and bid_volume are the last active counts in the interval.
• The dedicated data refreshes every 10 minutes and supports 30m, 1h, and 1d.

Variant version codes are p1, p2, p3, p4, and emerald. These codes are stable even if a display label changes.

Choose the series that matches the question#

Use general price history when you need comparable BUFF and cross-marketplace phase-wide candles, especially before May 19, 2026. Request the base Gamma Doppler market_hash_name, filter to source buff, and select the variant by its version.

Use dedicated BUFF history when float-specific pricing or avg_ask changes the answer. Discover the current bucket catalog with BUFF latest, then match the stable bucket_id in the history response. A phase-wide Emerald analysis uses its base bucket; an Emerald low-float analysis uses the appropriate Emerald float bucket.

Applicable endpoints#

Details that change the analysis#

• close_avg_ask is the closing average active ask. It does not average completed sales, so it should be read with the listing floor and ask_volume.
• A missing Emerald bucket is missing coverage. Filling it with a parent item or Phase 1 through Phase 4 value would create data the marketplace did not report.
• Compare premiums at matching bucket timestamps. Using an Emerald close and a base close from different intervals mixes overall market movement into the variant premium.
• The dedicated BUFF history has no data before May 19, 2026. The general endpoint cannot supply earlier float-range or average-ask history.
