# Volume Bubbles Volume bubbles: a bubble on each bar with outsized volume, sized by how far it exceeds its average, to highlight high-activity bars. ## How to read it - Green when the bar's taker delta is positive, red when negative (candle direction where no delta is known). - Bubbles sit at the bar's typical price. - Bubbles at swing extremes often mark climaxes. ## Key settings - MA length 20, minimum ratio 1.5 × average. - Max bubble size 16; opacity. ## Good to know - Drawn on the price pane, over the candles.
