The MESA adaptive moving average is a trend-following indicator. It adapts to price movements in a very unique way, based on the rate of change (ROC), as measured by the Hilbert Transform Discriminator.

Like other moving averages, traders use this indicator to spot trends and trend reversals. This is done by crossovers between a fast and a slow moving average. 

When the fast moving average crosses the slow one upwards, a buy signal is generated, and will hold this signal until a bearish crossover takes place. Likewise, when the fast moving average crosses the slow one downwards, it will signal a sell until a bullish crossover takes place.

Unlike other moving averages, MESA won’t only give a signal when the crossover between moving averages has taken place. It will signal a buy or a sell until the next crossover occurs.
