Title: How to check (percent_change) for Crypto Currencies upon custom dates?
Post by: ahmednabil88 on November 30, 2017, 04:17:57 AM
We can check (percent_change) for all Crypto Currencies now
Using coinmarketcap website
https://coinmarketcap.com/all/views/all/ (https://coinmarketcap.com/all/views/all/)
BUT ONLY for 
  • (percent_change) LAST 1 hour
  • (percent_change) LAST 24 hours
  • (percent_change) LAST 7 days


Any help/idea/tool
How to check (percent_change) for Crypto Currencies upon custom dates?
For example
Need to show (percent_change) for Crypto Currencies during this period
  • Start date: 01-01-2017
  • End date: 01-11-2017

just calculate it on your own!
the price history is out there, you can just open up any exchange that has that coin and check the price at those two dates and then calculate the percentage change of it.
Code:
[(price2 - price 1) / price1] * 100
or
Code:
[(price2 / price1) - 1] * 100

if you are familiar with programming then you can use poloniex chart API to get the price of a specific date

Ok, so you're asking specifically about CoinMarketcap. The answer is: You can't choose custom dates. Why? Because the CoinMarketcap site and mobile app don't offer that functionality.

What coin are you interested in historical data for? Google: [insert coin name here] historical prices

This will likely return you a few sites that provide historical price data for the coin you have interest in, and one of these sites should allow you to customize the date range.

If that doesn't work, follow Pooya's advice below:

Good suggestion and instead of manually calc the required (percent_change) for each currency one by one
The programmable app will do
Thanks!
