PPO (Percentage Price Oscillator)

stockcharts.com wrote: The Percentage Price Oscillator (PPO) is a momentum oscillator that measures the difference between two moving averages as a percentage of the larger moving average. As with its cousin, MACD, the Percentage Price Oscillator is shown with a signal line, a histogram and a centerline. Signals are generated with signal line crossovers, centerline crossovers and divergences. read more…
Formula: PPO = (EMA(12) - EMA(26)) / EMA(26) SIGNAL = EMA(PPO, 9) HISTOGRAM = PPO - SIGNAL

HI APPRENDICE ,
CAN YOU CREATE A STRATEGY BASED ON THIS INDICATOR PPO
INIDCATORS:
1.PPO DATA SOURCE PRICE(PPOP) BUY LEVEL:0 SELL LEVEL;0
2.PPO DATA SOURCE VOLUME(PPOV)
BUY LEVEL:0 SELL LEVEL:0
BUY;
PPOP CROSS OVER SIGNAL AND PPOP > BUYLEVEL AND PPOV > SIGNAL AND PPOV > BUY LEVEL
SELL:
PPOP CROSS UNDER SIGNAL AND PPOP< SELL LEVEL AND PPOV<SIGNAL AND PPOV < SELL LEVEL
