I see trading a risky one. You have to exert more effort and time for you to have a close monitoring on it. Also, Trading have gains and losses , you have to take it openly because that is the risk of trading had.
I think day trading or short trading would really be hard if you don't really know on what you are doing and the risk involve is on its volatility itself. If you are a trader and riding on the waves of price increase and decrease you would really need to have a nearly precise assumptions and basis on your buy or sell orders.
