Summary

Element-wise multiplication of two input series.

Reference data (CSV) · Chart (SVG)

Chart metadata i

Outputs

• outReal: line · zero · positive · negative

Formula

outReal[i] = inReal0[i] * inReal1[i]

Inputs

• inReal0 — First operand series
• inReal1 — Second operand series

Outputs

• outReal — Product of the two inputs at each index

Properties

Numerical Stability: Start-Independent

☐ Overlap Input
✅ Independent Y-Axis i
☐ Candlestick
☐ Display Shift

☐ Can Output NaN or ±Inf
☐ Identity at Period 1
☐ Uses Transcendental
☐ Input Must Be Positive

Example

C

#include <stdio.h>
#include <ta_libc.h>

int n = 252;
double series0[252]; /* your data, oldest first */
double series1[252]; /* your data, oldest first */
double out[252];
int outBegIdx, outNBElement;

TA_Initialize();
TA_MULT( 0, n - 1, series0, series1, &outBegIdx, &outNBElement, out );
printf( "%d values from bar %d; last out = %f\n", outNBElement, outBegIdx, out[outNBElement - 1] );

Rust

use ta_lib::Core;

let series0 = vec![0.0; 252]; // your data, oldest first
let series1 = vec![0.0; 252]; // your data, oldest first
let mut out = vec![0.0; 252];

let core = Core::new();
let range = core.mult(0, series0.len() - 1, &series0, &series1, &mut out)?;
println!("{} values from bar {}; last out = {}", range.count, range.beg_idx, out[range.count - 1]);

Java

import io.github.talib.Core;
import io.github.talib.OutRange;

double[] series0 = new double[252]; // your data, oldest first
double[] series1 = new double[252]; // your data, oldest first
double[] out = new double[252];

Core core = Core.DEFAULT;
OutRange r = core.mult(0, series0.length - 1, series0, series1, out);
System.out.println(r.count() + " values from bar " + r.begIdx() + "; last out = " + out[r.count() - 1]);

C#

using System;
using TALib;

var series0 = new double[252]; // your data, oldest first
var series1 = new double[252]; // your data, oldest first
var outReal = new double[252];

var core = Core.Default;
OutRange r = core.Mult(0, series0.Length - 1, series0, series1, outReal);
Console.WriteLine($"{r.Count} values from bar {r.BegIdx}; last outReal = {outReal[r.Count - 1]}");

TypeScript

import { mult } from 'ta-lib';

const series0 = new Float64Array(252); // your data, oldest first
const series1 = new Float64Array(252); // your data, oldest first

const { begIdx, values } = mult(series0, series1);
console.log(values.length + ' values from bar ' + begIdx + '; last values = ' + values[values.length - 1]);

Implementation

Added in 0.4.0.
