Mate, why are you looking for a short term in here? Trading, and holding for a long term shoot is always going to be much more profitable than just holding for some days or hours.
This is just my advice, i am just giving you some tips to make more profit

I always watch my portfolio all day long. Because i have some coins for short term. So ı want to sell them when their prize is up and buy more when prizes are down. It's good to watch when all my coins going up but if they start to decrease i do not look that much for not to be panic or feel bad.
