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.Merck & Co. Historical Data
