[−][src]Struct yata::methods::Cross
Searches for two timeseries lines of type ValueType
cross each other.
If value
crossed base
upwards, then returns Action::BUY_ALL
If value
crossed base
downwards, then returns Action::SELL_ALL
Else (if series did not cross each other) returns Action::None
Parameters
Has no parameters
Input type
Input type is (value
: ValueType
, base
: ValueType
)
Output type
Output type is Action
Examples
use yata::prelude::*; use yata::methods::Cross; let mut cross = Cross::default(); let t1 = vec![0.0, 1.0, 2.0, 3.0, 4.0, 5.0]; let t2 = vec![5.0, 3.0, 1.8, 2.9, 4.1, 5.6]; let r = vec![ 0, 0, 1, 0, -1, 0 ]; (0..t1.len()).for_each(|i| { let value = t1[i]; let base = t2[i]; let cross_value = cross.next((value, base)).analog(); assert_eq!(cross_value, r[i]); });
