Volume Bubbles Chart (1h)
Each 1-hour candle's volume is signed by its direction (up candles count as net buying, down candles as net selling) and drawn as a bubble at the closing price, green for buying and red for selling. Bubble size and colour intensity show how strong that flow is compared with the last 300 candles: the strongest 30% get full bubbles with their USD value, the rest stay as small dots. Unusually large bubbles flag aggressive buying or selling worth a closer look, often near breakouts, reversals or key levels.Seasonal Chart
Plots one line per calendar year showing the % change since the start of that year, with the current year highlighted against up to four previous years. Lining the years up on the same calendar shows whether the price tends to rise or fall in the same months, helping you spot recurring seasonal patterns. Treat it as context rather than a forecast: past seasonality does not guarantee future moves.OKB Derivatives

About OKB (OKB)
**OKB (OKB)** is the token associated with OKX, which describes itself as a cryptocurrency exchange. OKX's announcement on the X Layer upgrade and the OKB gas-token economic model states that OKB will continue to be the only gas and native token for X Layer.
The 2025 supply change
OKX announced a one-time burn of 65,256,712.097 OKB, accumulated from past buybacks and treasury reserves. The announcement says that after this operation is completed, the total OKB supply will be fixed at 21 million. The timeline lists the burn on August 15, 2025 and the OKB smart contract upgrade, which removes minting and burning functionality, on August 18, 2025.
Contract changes
The announcement says OKX will upgrade the OKB smart contract to remove minting and burning functionality after the burn. Historical repurchases, the one-time burn and the fixed supply are separate events, and users should compare the announcement with the current contract and OKX token information when assessing supply.
Reading the OKB chart
FMchart's OKB chart uses a composite market price from available sources and expresses it in USD. Prices on a single exchange can differ from the composite because of market conditions and data timing. The monthly and annual return tables report price changes over their displayed periods.
