// MACD divergence system
//
// This system detects MACD and MACD-H positive and negative divergences, and 
// crossovers.  

// This indicator/expansion is based completely on indicators/explorations written
// by other AFL contributors, all of them much cleverer than me. There is very 
// little original work here.

// As an indicator, it displays the usual MACD and MACD-H indicators. It also 
// displays a shape indicating where a divergence or crossover occurs.
// As an exploration, simply select n = 1, define the stock universe to be
// examined, and press the "Explore" button. The detected stocks are listed
// together with a red/green color-coded indication of the divergence or
// crossover
// Several parameters can be configured, including the minimum divergence and 
// histogram widths. Configure to suit your own requirements.

// This is still a work in progress, so if you have any suggestions or improvements,
// please let me know via the forum.

// MACD divergence system
//
// This system detects MACD and MACD-H positive and negative divergences, and 
// crossovers.  

// This indicator/expansion is based completely on indicators/explorations written
// by other AFL contributors, all of them much cleverer than me. There is very 
// little original work here.

// As an indicator, it displays the usual MACD and MACD-H indicators. It also 
// displays a shape indicating where a divergence or crossover occurs.
// As an exploration, simply select n = 1, define the stock universe to be
// examined, and press the "Explore" button. The detected stocks are listed
// together with a red/green color-coded indication of the divergence or
// crossover
// Several parameters can be configured, including the minimum divergence and 
// histogram widths. Configure to suit your own requirements.

// This is still a work in progress, so if you have any suggestions or improvements,
// please let me know via the forum.

Thanks,it’s very useful

2. davidalan

getting error line577 can anyone correct

3. viet

This is a great tool! Thanks for sharing! I will study the code and see what changes I can make to improve the indicator.

4. goldie

Somehow i got the MACD lines and the histogram showing as separate. Is there anything I need to change?
