Struct yata::methods::CrossUnder
source · [−]pub struct CrossUnder { /* private fields */ }
Expand description
Searches for value
timeseries line crosses base
line downwards
If value
crossed base
downwards, then returns Action::BUY_ALL
Else 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::core::Method;
use yata::methods::CrossUnder;
let mut cross_under = CrossUnder::new((), &(0.0, 5.0)).unwrap();
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, 0, 0, 1, 0 ];
(0..t1.len()).for_each(|i| {
let value = t1[i];
let base = t2[i];
let cross_value = cross_under.next(&(value, base)).analog();
assert_eq!(cross_value, r[i]);
});
