Enum BubbleColor 

pub enum BubbleColor {
    Side,
    Delta,
    Split,
    AbsoluteDelta,
    DeltaPercent,
    Volume,
}

What the colour of a bubble shows.

Variants

Side

The aggressor side with more volume, or the neutral colour on a tie and when no trade has a side.

Delta

The delta as a share of the volume with a side: the sell colour when every trade sold, the buy colour when every trade bought, and the blend between them in between.

Split

Two circles on one centre, each sized by its own side’s volume, so the smaller one shows inside the larger: the sell colour for the bid side, the buy colour for the ask side. Volume of unknown side is left out, and a bubble without any volume with a side is one neutral circle.

AbsoluteDelta

The sign of the delta picks the buy or sell colour, and its absolute size, relative to the largest absolute delta of the visible bubbles, the opacity, down to a fifth of it. A zero delta, and a bubble without volume with a side, take the neutral colour.

DeltaPercent

The delta as a share of the whole volume, unknown side included: the neutral colour when it is zero, fading to the buy or sell colour as the share nears 100%, so volume of unknown side pulls the colour toward neutral.

Volume

The neutral colour for every bubble: the diameter alone shows the volume.
