MACDAS

The MACDAS indicator tracks momentum shifts by applying an Exponential Moving Average (EMA) to the MACD histogram to generate earlier entry and exit signals than the standard MACD.

Usage

The MACDAS is used to identify trend reversals and momentum exhaustion before they become apparent in lagging indicators. Traders primarily utilize this tool to find early entries based on the interaction between the MACDAS line and its signal line.

• Bullish Crossovers: A bullish signal is generated when the MACDAS line (the smoothed histogram) crosses above its signal line. This often serves as a leading indicator for a trend shift.
• Bearish Crossovers: A bearish signal occurs when the MACDAS line crosses below its signal line, suggesting that upward momentum is fading.
• Zero Line Rejections: Monitoring how the MACDAS reacts near the zero line can help traders identify whether a trend is strengthening or if a mean reversion is likely.

The settings allow users to adjust the sensitivity of the calculations. Shorter periods will result in more frequent signals, while longer periods filter out market noise at the expense of increased lag.

Details

The MACDAS is based on the methodology popularized by Thomas Aspray. While a standard MACD compares two moving averages of price, the MACDAS operates as a "derivative of a derivative." It calculates the difference between the MACD and its signal line (the histogram) and then applies a secondary 9-period EMA to that result.

In this implementation, Exponential Moving Averages (EMA) are used for all calculation steps—including the initial MACD construction—to ensure the script reacts more sensitively to recent price action compared to Simple Moving Average (SMA) variants. By smoothing the histogram itself, the indicator highlights changes in the rate of change of momentum.

Settings

• Fast Period: Defines the lookback period for the shorter EMA used in the base MACD calculation.
• Slow Period: Defines the lookback period for the longer EMA used in the base MACD calculation.
• Signal Period: Determines the smoothing length for both the original MACD signal line and the final MACDAS signal line.

FAQ

How does MACDAS differ from the standard MACD? Standard MACD focuses on the relationship between two price averages, whereas MACDAS treats the MACD histogram as the primary data source and applies a signal line to it, providing faster reaction times to momentum shifts.

What is the best way to interpret the signals? The most common application is watching for crossovers between the MACDAS and its signal line. Because it is highly sensitive, it is often used in conjunction with other trend-following tools to confirm entries.
