It's just as simple as this both goes hand in hand both for technical and fundamental analyst. Trading is one career that requires steady update on how the new could affect the direction of a trade or possibly how an indicator or a candle stick can direct a trader on where the market is heading. If there is no time for a consistent update on your previous knowledge as a trader I guess at some point some level of gambling sets in.

A successful trader isn't a trader who makes consistent profit without any loss but rather a trader who knows why his trade went the opposite direction and also a trader who understand risk management. Most traders makes massive profit in a single trade and blows everything down in the next trade as such there is no professional despite his initial achievements. To maintain clean records of both profit and loss margin reading as a trader is inevitable because despite the level of knowledge you might have acquired there must always be a newer technique you learn each time you seek to update your previous views about how the market behaves.

Only gamblers stay a full month without refreshing their memories on what the already know because in as much as trading is concerned there are multiple ways of predicting market flows and it only takes consistent research to get a hand full of approach to maintain a good profit margin in trading.
