What is Support and Resistance button?
Support and Resistance button draws horizontal support and resistance references from prior chart highs and lows. Blue and gray dots mark the displayed levels on the MT4 price chart.
The S&R button controls visibility when a cleaner chart is preferred. The package includes an .mq4 file and keeps the level display separate from the main candle data.
How to use Support and Resistance button
Review the dotted levels with the corresponding highs, lows, and nearby candle structure. The displayed history can provide a consistent visual reference while the chart is examined across timeframes.
SRcode and SRsize control the level calculation and dot size. The button inputs control position, text, colors, and dimensions; their default values are shown in the parameter table.
Where it helps
Prior highs and lows are converted into a consistent dotted display.
The S&R button can show or hide the level view.
Dot size, button position, text, colors, and dimensions are configurable.
