Every good trader uses his or her own style based on the reason that any index suits itself. And it is not a requirement to use a specific index of all good traders. You can pick indexes and analyze movements and combine them with others and keep trying until you find the best combination that works for you. I think the trader uses his own technique with every indicator he finds suitable for him. I think the specific indicators used by all traders are good. I also think that you can choose indicator and analyze movement.
