GBP/JPY is developing wave C of medium term downtrend (colored magenta in the chart). Within this wave C there are A-B-C subwaves (colored red) with subwave C still developing. And there are 5 waves of still smaller degree in the latter C subwave - colored yellow in the chart. The targets of the downmove are Fibonacci expansions off 133.03-130.75-131.61 (A-B waves), 131.61-129.55-130.30 (A-B subwaves), 130.30-129.23-129.72 (waves 1-2), 129.72-128.28-128.70 (waves 3-4).
Supports:
- 127.99-92 = confluence area of two expanded objective points (XOP)
- 127.81 = contracted objective point (COP)
- 127.26 = objective point (OP)
- 126.97-92 = confluence area of XOP and super expanded objective point (SXOP)
If the price reverses up its resistances will be Fibonacci retracements of the downwave from 130.30 - this wave is not developed yet.
Overbought/Oversold
Assuming that the prevailing trend is up it's preferable to use overbought readings of the Detrended Oscillator in conjunction with Fib resistances. The overbought area is 30-40 pips away from the current price.
