Anyone who knows chart interpretation supposed would have known indicator analysis, so that is the reason why we continue to be emphasizing directly to the learning the rudiments of trading and knowing the foundation of trading before venturing into it, i believe that trading is one of the major thing that we have to understand that it's disadvantages is higher than the advantages.
Charts first, then followed by learning about indicators.
Charts and indicators are not the same. What contain in the charts are open, high, low and close price at a particular peeriod of time, it may also contain other information like number of transactions and volume etc. But indicators are primary ones like MA, EMA and BB, or secondary ones like RSI and other oscillating indicators.
It is easy for traders to learn and know charts, it may be not be hard to learn and know about indicators, bit it take longer time to learn than charts. Charts would first be learend before indicators too.
