We have a Google Cloud Compute Engine that regularly retrieves the prices and calculates the RSI via a custom Python script.
I just check out the site and it looks pretty cool. It would be a big help for the traders to know the coins that are currently on sale. Just a suggestion though since beside the coin there is a view market and when I click it, it goes directly to Bittrex so can you also add OP the link directly to binance? It would be a good way also to check if there are arbitrage opportunities to the coins since as you stated the API is from both exchanges so having the view markets link to both exchanges would be convenient. I know we can just go to binance and check the price of the coins ourselves but it would be a great help if we can directly check it from the link in your site.
