How I want to get 100pips perday ?what should I do and what indicator I must using?

Answer
You question will get a lot of scam website references.

Forex is a seriously competitive market dominated by experts, not a market for simple easy profits. Anyone who claims otherwise is lying.

Imagine that someone could generate 100 pips per day easily. That person would become fabulously wealthy by trading daily. The person would not dilute their own returns by selling a system or robot. They certainly wouldn't give away the secret to strangers.

If you think it is easy, you will lose your entire investment quickly.

what are the average daily ranges of the major forex pairs?

Answer
70-100 pip a day
