yes scalping can be done without using any indicators but with good strategies and technical analysis helps us to do scalping in a very good way too. Good experience is also very necessary and that means swimming without a life jacket and lack of knowledge of swimming because no matter what someone like that does, he will definitely sink because it is only a matter of time and I am very confident about that fact because there is no place to hold on when you are in the water and it is similar to the forex market too
