The parameters of the chart types that need them. Sizes are in price units and are used as given; a size the chart cannot use is reported on the chart instead of being replaced.

Fields

styles: ChartTypeStyles

Independent line, area and baseline styles, retained across chart type changes.

renko_size_method: BoxSizeMethod

Renko: method resolved once from loaded history, then frozen while bars stream.

kagi_size_method: BoxSizeMethod

Kagi: method for its reversal amount.

range_size_method: BoxSizeMethod

Range bars: method for their range.

pnf_size_method: BoxSizeMethod

Point and Figure: method for its box size.

renko_source: PriceBasedSource

Renko: close or high/low input, also used for wick extremes.

kagi_source: PriceBasedSource

Kagi: close or high/low input.

line_break_source: PriceBasedSource

Line Break: close or high/low input.

pnf_source: PriceBasedSource

Point and Figure: high/low, the traditional method, or close input.

renko_wicks: bool

Draw Renko wicks from the brick’s actual high and low.

renko_brick_size: f64

Renko: size of a brick.

kagi_reversal: f64

Kagi: the move against the line that starts a new line.

range_size: f64

Range bars: the range of a bar from its low to its high.

pnf_box_size: f64

Point and Figure: the size of a box.

pnf_reversal: u32

Point and Figure: the number of boxes a move against the column must cover to start a new one.

line_break_count: usize

Line Break: the number of lines a close must break through to reverse, 1 to 10.

baseline: BaselineLevel

Baseline: where the base line is drawn.

columns_base: Option<f64>

Columns: the price the columns rise above or fall below; None draws them up from the pane bottom.

tpo_period_minutes: u32

TPO: minutes per period, raised to the bar interval when shorter.

tpo_initial_balance_minutes: u32

TPO: minutes from the session open included in the initial balance, 60 by default.

tpo_poor_highs_lows: bool

TPO: mark the highest and lowest rows when they hold more than one TPO.

tpo_initial_balance_extensions: bool

TPO: draw one and two initial balance ranges above its high and below its low.

tpo_row_ticks: u32

TPO: instrument ticks per price row. Zero, or an instrument without a tick size, fits about 40 rows to the visible price range, each a whole number of the instrument’s ticks when it has a tick size.

tpo_value_area: f64

TPO: share of the TPOs in the value area, in percent.

tpo_split_sessions: bool

TPO: separate profiles for pre-market, regular and post-market hours.

tpo_single_prints: bool

TPO: highlight the rows touched by a single period.

tpo_letters: bool

TPO: paint each period’s letter inside its block.

tpo_composites: Vec<RangeInclusive<DateTime<Utc>>>

TPO: sessions combined into one profile, as in TPOConfig::composites.

Implementations

impl ChartTypeParams

pub fn tpo_config(&self, tick_size: Option<f64>) -> TPOConfig

The TPO settings for an instrument with minimum price increment tick_size, as the TPO chart type builds its profiles with them.

pub fn with_atr_renko(atr: f64, multiplier: f64) -> Self

Create with ATR-based Renko brick size

impl Debug for ChartTypeParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ChartTypeParams

fn default() -> Self

Returns the “default value” for a type.
