Agreed, from constant researching as a trader you get to know many things about the market that'll help you the next time you want to trade. Research gives you wisdom about the market and experience also gives you wisdom hence they're both very important for a trader to have. There isn't going to be a good trader that doesn't do his research regularly. You have to be doing more research than you're trading because for a majority of your trades to be accurate at all times, it has to show that you have knowledge of what you're doing. Research is what makes a trader great and it isn't about just doing random research but knowing how to do your research correctly and interpret the market in the right way. Professional traders are good at researching and they too have the experience that they learnt and ready to make use when they're researching for future trades.
