GBP/JPY is developing potential impulse wave 5 (colored light green in the chart) of medium term downtrend from 120.78. Within this wave there are five subwaves (colored red in the chart), and subwave A is now developing against the downtrend from 116.91. The targets of the upmove are Fibonacci retracements of 120.78-116.91, and 127.31-116.78.

Resistances:

- 118.85 = .50 retracement
- 119.30 = .618 ret
- 120.80 = .382 ret

However if the downtrend resumes and the price breaks below 116.78, the immediate supports will be Fibonacci expansions off 130.81-123.27-127.31, 127.31-116.78-120.78, 120.78-119.06-120.73, 120.73-117.66-119.06.

Supports:

- 116.23 = super expanded objective point (SXOP)
- 115.99 = objective point (OP)
- 115.11 = expanded objective point (XOP)
- 114.27 = contracted objective point (COP)
- 114.09 = XOP

Overbought/Oversold

Assuming that the major wave is now down it's preferable to try short positions when the Detrended Oscillator gets above the zero level (10-20 pips above the current prices) or into the overbought area (40-55 pips above the current prices).
