Index Divisor Initialization

Install and import

bash
npm install fintech-algorithms
ts
import { calculate } from "fintech-algorithms/index-and-benchmark-engineering/index-initialization-and-continuity/index-divisor-initialization";

Signature

calculate(data)

Worked example

verified This is the worked example published in the article, replayed by the test suite on every run. The output cannot drift.

Input

data
{
  "marketValue": 125000000,
  "baseLevel": 1000
}

Call

calculate(data)

Returns

object with 3 fields: marketValue, divisor, indexLevel

{
  "marketValue": 125000000,
  "divisor": 125000,
  "indexLevel": 1000
}

How it works

This page states the contract — how to call it correctly. The article explains the concept: why it works, and where it breaks.
