Enum yata::core::Action

pub enum Action {
    Buy(u8),
    None,
    Sell(u8),
}

Action is basic type of Indicator’s signals

It may be positive (means Buy some amount). It may be negative (means Sell some amount). Or there may be no signal at all.

You can convert Action to analog i8 value using analog() method, where:

• 1 means buy;
• -1 means sell;
• 0 means no signal.

You can convert Action to digital Option<f64> value using ratio() method with internal value in range [-1.0; 1.0], where:

• negative value means sell some portion;
• positive value means buy some potion;
• zero value means there is no distinct decision;
• None means no signal.

Variants

Buy(u8)

Buy signal

None

No signal

Sell(u8)

Sell signal

Implementations

impl Action

pub const BUY_ALL: Self = _

Shortcut for Buy All signal

pub const SELL_ALL: Self = _

Shortcut for Sell All signal

pub fn from_analog(value: i8) -> Self

Create instance from analog signal (which can be only -1, 0 or 1)

Any positive number converts to BUY_ALL

Any negative number converts to SELL_ALL

Zero converts to None

pub fn ratio(self) -> Option<ValueType>

Converts value with the interval [-1.0; 1.0]

pub fn analog(self) -> i8

Returns a sign (1 or -1) of internal value if value exists and not zero.

Otherwise returns 0.

pub fn sign(self) -> Option<i8>

Returns a sign of internal value if value exists

Otherwise returns None

pub const fn value(self) -> Option<u8>

Return an internal representation of the value if signal exists or None if it doesn’t.

pub const fn is_none(self) -> bool

Checks if there is no signal

pub const fn is_some(self) -> bool

Checks if there is signal
