t must look across all USA Stocks that is traded on Exchanges : Nasdaq, Nyse, Amex and have volume traded today bigger than 1mln. so on all of this stock look for this pattern and give alert, when it appears.
Step 1: Identify Swing Highs & Lows on 1 minute timeframe
- price bars that stand out from the 5 bars on each side (left and right). A swing high is a bar whose high is higher than the 5 bars before and after it. A swing low is a bar whose low is lower than the 5 bars before and after it.
Step 2: Draw Horizontal Lines
When a swing high/low is identified, the scanner draws a horizontal line from that point extending to the right of the chart.
Step 3: Monitor Price Returns
The scanner continuously watches for price to return to these horizontal lines. When price approaches and touches the line:
*  Resistance: Price touches from below and closes below the line
* Support: Price touches from above and closes above the line
Step 4: Generate Alerts
