What is HamaSystem button Indicator?
HamaSystem button is an MT4 indicator that displays a HAMA moving-average system with an on-chart button for showing or hiding the lines. The Hama MA period controls the smoothing used for the displayed average.
The indicator also includes optional screen, sound, push, and email notifications, along with settings for button text, colors, size, and position. These options organize chart review without adding a fixed interpretation to the display.
How to Use It in Practice
Use the HAMA display and button as chart-review controls:
- Add HamaSystem button to an MT4 chart and review the displayed HAMA lines.
- Use the chart button to show or hide the moving-average display.
- Adjust Hama MA period when a different smoothing level is preferred.
- Enable the existing alert options and customize the button position, text, colors, and size as needed.
The HAMA display can be toggled without removing the indicator, notification options cover several delivery methods, and the button layout is configurable for different chart workspaces.
