Absolute Price Oscillator (APO)

Absolute Price Oscillator — the absolute difference between a fast and a slow EMA. Absolute Price Oscillator (APO) shows the absolute (not percentage) difference between a fast and a slow EMA. Unlike PPO, the APO value depends on the asset’s price. It is used to determine the direction and strength of a trend.

Formula:

APO = EMA(fast) - EMA(slow)
Signal = EMA(APO, signal_length)
Histogram = APO - Signal

TriggerDirectionConditionDescription
Signal line cross up🟢 BuyThe main line crossed the signal line from below to above — a buy signal.The APO line crosses the signal line from below to above — a bullish crossover.
Signal line cross down🔴 SellThe main line crossed the signal line from above to below — a sell signal.The APO line crosses the signal line from above to below — a bearish crossover.
Zero cross up🟢 BuyThe indicator line crossed zero from below to above — a buy signal.The APO line crosses the zero level from below to above.
Zero cross down🔴 SellThe indicator line crossed zero from above to below — a sell signal.The APO line crosses the zero level from above to below.
Histogram crosses zero up🟢 BuyThe histogram crossed zero from below to above — a buy signal.The histogram (APO) crosses the zero level from below to above — a bullish signal.
Histogram crosses zero down🔴 SellThe histogram crossed zero from above to below — a sell signal.The histogram (APO) crosses the zero level from above to below — a bearish signal.
Slope turns positive🟢 BuyThe indicator slope turned positive — an upward reversal.The APO line changes its slope from descending to ascending — the indicator stopped falling and started rising.
Slope turns negative🔴 SellThe indicator slope turned negative — a downward reversal.The APO line changes its slope from ascending to descending — the indicator stopped rising and started falling.
Line diverges from signal↕️ BothThe distance between the main line and the signal line increased by the specified amount.The APO line moves away from the signal line — momentum is strengthening.
Line converges to signal↕️ BothThe distance between the main line and the signal line decreased by the specified amount.The APO line converges to the signal line: the distance shrinks, a crossover may be building up.
