Look brother,
1st
Volatility is only for a day trading between 30 min trade to 8 hours trade.
I do use onlu eur/usd , gbp/usd and sometimes eur/gbp and can/usd
I do check volatility to use the pivot point strategy ONLY in M15 frame.
2nd your target is OCTO look formula that gave u already
about expert you can make it if you can program it.
