Stephis Supply & Demand Zones v3

📉 Support
Definition: Support is a price level where a downtrend can be expected to pause or reverse due to a concentration of buying interest.
Why it matters: When the price of an asset falls to a support level, traders expect buyers to step in, preventing the price from falling further.
Visual clue: On a chart, support often appears as a horizontal line where the price has bounced up multiple times.
📈 Demand
Definition: Demand refers to the willingness and ability of buyers to purchase an asset at a given price.
In trading context: High demand typically pushes prices up, while low demand can lead to price drops.
Relation to support: A support level exists because of demand—buyers are willing to buy at that price, creating a floor.
🧠 How They Work Together
When price approaches a support level, traders watch to see if demand increases—if it does, the price may bounce.
If the support level is broken, it may signal that demand has weakened, and the price could fall further.
🔁 Opposite Concept: Resistance & Supply
Resistance is the opposite of support—it's a level where selling pressure (supply) may stop a price from rising.
Just like demand creates support, supply creates resistance.
