@lightflower Basically everything in the green means positive price changes in the last 24 hours and then the bars are the percentages.

He also created an index with different coins where he put the bulk into Bitcoin, Ethereum Ripple and Bitcoin Cash and then some in other coins. He created another index with Bitcoin, Ethereum, Bitcoin Cash, QTOM and EOS, which he rebalances every month. Then he tracks performance for both indexes over time and compares them.

You can try something like that yourself on a site like coinlib. I've created an article some time ago where I use that site.

Thanks @koreaculture
