What is SD_SR_But CU?
SD_SR_But CU automatically plots several support and resistance zones and assigns a color and label to each zone. The labels include Weak Support, Verified Support, and Turncoat Support, with corresponding resistance states.
The labels are intended to keep the relative history of a zone visible while the chart is reviewed. They are reference categories, not an automatic decision about future price behavior.
How to use SD_SR_But CU
Apply SD_SR_But CU to an MT4 chart and compare the color and strength label of each zone with the recent price reactions around it.
Use the zone, label, and color inputs to reduce clutter and keep the strength categories readable on the selected timeframe.
Where it helps
Separates weak, verified, and turncoat support or resistance states.
Draws multiple horizontal areas without requiring every level to be placed manually.
Makes the zone classification visible directly on the chart.
