Trading: short term, emotional based
Investing: long term, fundamental based
So you say both are trading, only difference is in time, first one is short other is long term?! In my opinion trading is gambling, you gamble on the outcome, you buy or sell because you believe the price will rise or drop, you are trying to predict what will happen and you make your bets. In my opinion, based on years of doing both, both are like games, they have some similarities, but also they have differences, like different games, you can't put Counter Strike, League of Legends and Puzzles in the same basket, each has its own rules and regulations, you can play all of them with the same strategy.
Investing is everything you do with your money, you invest in what you believe is best for your skills (at least it should be like that, but some people are just lucky guessing and hope for the best). You can invest in trading, or gambling, or anything else, and when you invest you hope that it will bring some profit, depending on the game and strategy you will know results after few seconds or few months!
Investing or trading both have similarities with gambling but not complete at all,you can make profits from making right analysis but in gambling its impossible to analyse things except sport prediction games.And you can apply same strategies for both but if you are interested in making more money then you have to separate things.
For trading you have to be more concentrating on technical analysis and needs to be more active.
