About OsMA Indicator
The OsMA (Moving Average of Oscillator) indicator, documented at axiory.com and available in numerous enhanced variants (SC MTF Osma, OsMA Arrow MTF, Color OSMA, BB OSMA) via mql5.com and forexmt4indicators.com, is the difference between the MACD line and its signal line — effectively the MACD histogram displayed as a standalone indicator.
Based on MACD principles, it measures the difference between the 12-period and 26-period EMAs relative to the signal line, reflecting current price momentum and the potential for trend continuation or reversal. Bars oscillate around a zero line: positive/green bars indicate bullish momentum, while negative/brownish-red bars indicate bearish momentum. It's popular among day and intraday traders for identifying momentum shifts.
