doppelgunner-stock api

Api for getting historical-prices and analyzing its data.

Installation

npm install --save doppelgunner-stock

Samples

Loading of historical prices from WSJ.

• Note: internet is required
• Note: important to pass function callback to execute when downloading finished

import { HP, HPCommons, HPModel } from 'doppelgunner-stock';

HP.load(HP.downloadWSJ('X',false,'PH'), funcCallback);

OR

HP.load(HP.downloadWSJ('X',false,'PH'), () => {/*something to do here*/});

Function callback

• Note: better to make promise for chaining
• Note: This sample extracts and displays all dates

function funcCallback(hpModel) {
    new Promise((resolve,reject) => {
        resolve(hpModel);
    }).then(xurpas => HPCommons.getColumn(xurpas, 'date'))
      .then(dateColumn => console.log(dateColumn));
}

Limitations

• Downloads from WSJ as of now
• Only historical-prices
