When 15min RSI hits its Bounce Area, prices either take support at 50%FR or 61.8%FR, currently its taking support at 50% FR. With that recent low of 507 being a stop on 15 min basis, its a long trade for an initial target of 516 (61.8%FR of fall from 522). Eventual target is 534.
A break of the low of 507, would result in a test of the lower end of the Gap Area 502. Will look for a long entry again at 502.
