I would like to share this http://cryptomarketscanner.com/, it is a great tool for giving signals of positive or negative change in the market value. You could change the settings of checking period, percentage change, minimum volume, base currency and exclude coins as well. It simply runs on the browser and you can leave it in tab, gives a buzzing sound when there are markets that met your criteria(settings). Currently covers 7 exchanges but still a good use. Best of it, you can use the scanner for FREE. Good for day traders like me.
