marketcap-filter

A simple nodeJS script to filter coinmarketcap microcap coins using the coinmarketcap api.

This script is based on the methodology described in this medium article by nik :

Picking Out Microcaps 101

---

Note: Please respect coinmarketcap's API limit request of no more than 10 per minute. This version also uses a direct 'maxsupply' filter instead of a 'supply ratio'.

---

Installation :

• Requires nodeJS and npm to be installed.
• clone the repo: git clone https://github.com/jolleyjoe/marketcap-filter.git
• cd marketcap-filter
• npm install

Running the script :

• From project folder: node query.js [options]

Required options:

• --maxmc : The maximum market cap you wish to query in USD (--maxmc=250000 recommended in article)
• --volmcratio : The min ratio (%) of 24 hour volume to marketcap (--volmcratio=2 recommended in article)
• --maxprice : The maximum price in USD per coin
• --maxsupply : The maximum available coin supply (e.g. --maxsupply=50000000 would mean that you will exclude coins with a greater available supply than the maxsupply given)

Optional:

• --sort : Sort by one of the following (If no --sort option is given, the default is 'rank') :
  • marketcap : The total marketcap in USD
  • price: The price in USD
  • rank: The coinmarketcap ranking
  • supply: The ratio of total vs available coins

Sample usage:

• node query.js --maxmc=250000 --volmcratio=2 --maxprice=1 --maxsupply=50000000 --sort=supply

Creating standalone programs

Disclaimer: This is the way I did it and not the only way!

• You can create a binary by using the pkg library.
  • npm install -g pkg
  • Run pkg query.js to create 3 x binaries, one for Linux, MacOS and Windows.
  • Run pkg --help for options.
• You can then execute the binary directly without invoking node query.js.

There are other ways to create node command line utils. Great post here
