Two detection mechanisms

How CSPump identifies quiet accumulation

China-Surge (CN Lead)

Pumps and accumulation phases often start on Chinese marketplaces (Buff163, Youpin, C5Game) hours or days before Western markets react. CSPump catches this cross-market lead.

Supply Drain

Active marketplace listings drop at an abnormal rate across CSFloat, Buff163, and Steam while prices remain flat, revealing quiet position-building.

Volume vs flat price

A surge in daily turnover without an immediate price jump is the signature footprint of accumulation before the supply shock triggers a pump.

What gets accumulated

Cases, stickers, and rare weapon finishes

Discontinued cases

Rare drop pool and operation cases quietly absorbed from circulating supply until a supply shock occurs.

Tournament capsules

Discontinued major capsules and high-demand tournament stickers undergoing multi-week absorption before rallies.

Trade-up & play skins

Covert trade-up inputs, popular play skins, and operation collections thinned out on order books.

FAQ

Common questions about CS2 accumulation

What is CS2 accumulation?

Accumulation is quiet, sustained buying that often precedes a pump. Traders or investors systematically absorb listings across Western and Chinese marketplaces at current market prices without bidding up the order book.

How does China-Surge detection work?

Chinese exchanges account for a massive share of CS2 liquidity. When abnormal buying surges on Buff163 or Youpin before Western platforms react, CSPump flags a China-Surge accumulation signal.

Is accumulation detection included in the Free tier?

Free tracks items in your own CS2 inventory and alerts you when they pump on Steam. Accumulation detection (both China-Surge and Supply Drain across the full catalog and custom watchlists) is an advanced feature included with CSPump Pro, with a 7-day free trial.
