This is a great tool. One thing to note that i ran into; If you are having issues with low market cap coins, the part of the script here:
var url = "https://api.coinmarketcap.com/v1/ticker/?convert=USD&limit=70";
limits the coin lookup to the top 70 market cap. You can change that to 100,400, or 800 to your liking to get all coins. Thanks
