The indicator on the quadrangle patterns, designed to work on hourly timeframes.

Indicator displays quadrangle figure, angles of which are

1. Daily Open
   
2. Daily High
3. Daily Close
4. Daily Low

The essence of the system is visual determination of subsequent movement:

• If the latter figure has a narrowing and the narrowing is less than the base of the figure, it forecasts continuation of a trend (at least the size of the base)
• If the latter figure has an expansion and the expansion is greater than the base of the figure, it predict possible reversal (at least the size of the base)
• If the base and the end of the figure are visually equal, a correction is expected
  

• Narrowing 3 is less than base 1 == trend continuation is predicted
• Narrowing 4 is approximately equal to the base 2 == flat is predicted
  
• Narrowing 6 is greater than base 5 == change in the trend is predicted
• Narrowing 9 is greater than base 7 == change in the trend is predicted
• Narrowing 11 is greater than base 8 == change in the trend is predicted
