TD Sequential

Implementation of TD Sequential Indicator in node.js.

Tom Demark Sequential indicator specifies when a trend is forming or is getting exhausted, and when to get into a trade. It is widely used in Forex, stock market, and cryptocurrency trading.

TD Sequential indicator consist of two components. TD Setup is the first one and it is a prerequisite for the TD Countdown

Package Description

This module is an implementation of TD Sequential in node.js based on this link.

The input is an array of ohlc (open, high, low, and close) values. For example:

let ohlc = [{
  open: 100,
  high: 200,
  low: 10,
  close: 50,
}, ...
]

The output is an array of the same size where each entry has the following fields:

{
  buySetupIndex: 0,                                 //Counting for buy setup
  sellSetupIndex: 0,                                //Counting for sell setup
  buyCoundownIndex: 0,                              //Counting for buy countdown
  sellCoundownIndex: 0,                             //Counting for sell countdown

  countdownIndexIsEqualToPreviousElement: true,     //Indicates that the countdown index on item i is the same as i-1

  sellSetup: false,                                 //Indicates Sell setup happened
  buySetup: false,                                  //Indicates Buy setup happened
  sellSetupPerfection: false,                       //Indicates a perfect Sell Setup
  buySetupPerfection: false,                        //Indicates a perfect Buy Setup

  bearishFlip: false,                               //Indicates a bearish flip happened
  bullishFlip: false,                               //Indicates a bullish flip happened

  TDSTBuy: 0,                                       //highest high(usually the high of bar 1) for a buy setup
  TDSTSell: 0,                                      //the lowest low(usually the low of bar 1) for sell setup
  countdownResetForTDST: false                      //Indicates the countdown got reset due to observing TDST
}

Install

npm i -S tdsequential

Usage

var TDSequential = require("tdsequential");

let result = TDSequential([
  {
    time: 1525651200,
    close: 9377.81,
    high: 9662.23,
    low: 9202.13,
    open: 9643.99,
    volume: 73842.44,
  },
  ...
]);

console.log("result: ", JSON.stringify(result, null, 2));

Below is an example screenshot. The setup numbers are annotated on the top, and the countdown numbers are annotated on the bottom.

A perfrect setup is highlighted with a "P" mark.
