Package Exports
- data-forge-redis
- data-forge-redis/build/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (data-forge-redis) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
data-forge-redis
The redis module for use with Data-Forge and recoded from data-forge-fs.
Supposedly, we have a series of data that has been stored in the redis database.
Unlike the module of data-forge-fs, the data structure of the securities is constructed as follows:
KEY FIELD VALUE [PREFIX]SYMBOL YYYYMMDD {"O": XX.XXX, "C": XX.XXX, "H": XX.XXX, "L": XX.XXX}
This library contains the redis extensions to Data-Forge.
The example code is listed as follows:
const dataForge = require('data-forge');
const dataForgeRedis = require('data-forge-redis');
require('data-forge-indicators');
var toDate = new Date();
toDate.setDate(toDate.getDate() - 8); // get the last 7 days data, today's data is not imported
var fromDate = new Date(toDate.getTime());
const options = {
host: localhost,
port: 3679,
database: 11
};
// async call, please use it in a async function, otherwise it will cause issues
var dataFrame = await dataForgeRedis.fromRedis(options).load(symbol, fromDate, toDate);
// for symbol that is stored with a prefix
// var dataFrame = await dataForgeRedis.fromRedis(options).load(symbol, fromDate, toDate, 'asx:price:');
var inputSeries = dataFrame.parseDates('date').setIndex('date').renameSeries({date: 'time'});

See Data-Forge docs and guide for details on how to use.
For company code changes
// for symbol that is stored with a prefix and code changes data is stored with a prefix as well
var dataFrame = await dataForgeRedis.fromRedis(options).load(symbol, fromDate, toDate, 'asx:price:', 'asx:cc');
