NG [Wave Period Oscillator]
The WPO is a short-term oscillator that measures the buying and selling period of price cycles over a certain time interval.
The leading oscillator indicates a rise in buying period when it moves above the zero line and a rise in selling period when it moves below the zero line.
Trading Tactics
Center line Crossover: a bullish center line crossover occurs when the WPO line moves above the zero level to turn positive.
A bearish center line crossover occurs when the WPO line moves below the zero level to turn negative.
When bulls are in control, the price rally begins and the average of the bull’s period T increases to drive the WPO line above the center line.
A buy signal is subsequently triggered.
When the bulls start to loose power, prices move sideways and the average period decreases. In this case, the WPO line may fl utter near the center line and cause false signals, whipsaws.
To avoid the whipsaws occurring on the center line, the following trading tactics are proposed:
Uptrend Tactic:
During an ideal uptrend, the WPO does not reach the lower boundary -2 and usually rebounds from a higher level than -2.
This means that the bulls have taken control earlier. Hence, a zero line crossover generates a buy signal. The WPO crosses the upper boundary at +2 then pulls back again below +2 to generate a sell signal.
Sideways Tactic:
During sideways, the WPO fluctuates between the lower and upper boundaries -2 and 2. This tactic is also used in an uptrend where corrections are strong enough to drive the WPO line below the lower boundary.
Downtrend Tactic:
During downtrends, the WPO fails to reach the upper boundary and oscillates between the 0 and -2 levels. The bears enter early indicating an obvious weakness in the market. Therefore, crossing the zero level generates a sell signal.
Exit at Weakness:
During uptrend reversals and downtrends, the WPO oscillates between the center line and the lower boundary -2. The bears are controlling the market and move in wide cycle periods while the bull’s strength is almost absent.
An exit signal is triggered once the WPO crosses -2. When prices decline, the WPO may cross its extreme lower boundary at -2.7. Therefore, a swift exit signal is triggered once the WPO crosses -2.
Re-Entry:
During uptrend, the WPO crosses down the upper boundary level at +2 to generate a sell signal. Yet, it does not reach the zero line and the oscillator moves back toward the upper boundary.
This case is considered as strength while a re-entry signal occurs at the +2 level crossover. The sell signal is generated when the WPO line crosses down the upper boundary.
The leading oscillator indicates a rise in buying period when it moves above the zero line and a rise in selling period when it moves below the zero line.
