GBP/JPY is developing impulse wave C (colored light green in the chart) of medium term uptrend from 116.91. Within this wave there are three subwaves (colored royal blue in the chart), and potential subwave C is still developing from 119.93. Within the latter wave there also three waves (colored magenta in the chart) with subwave C developing from 120.62. The targets of the upmove are Fibonacci retracements of 130.81-116.78, and expansions off 116.78-120.78-116.91, 116.91-122.58-119.93, 119.93-122.04-120.62, 120.62-122.01-121.06.

Resistances:

- 122.45 = objective point (OP)
- 122.73 = OP
- 123.31-38-43 = confluence area of expanded objective points (XOP) and contracted objective point (COP)

If the price reverses to the downside the immediate supports will be Fibonacci retracements of 120.62-122.45, 121.06-122.45.

Supports:

- 121.76-75 = .50 and .382 retracements
- 121.59-54 = .618 and .50 retracements
- 121.39 = .618 ret

Overbought/Oversold

Assuming that the major wave is now up it's preferable to try long positions when the Detrended Oscillator gets below the zero level (current prices) or into the oversold area (30-45 pips below the current prices).
