What is P4L BoxFibo?
P4L BoxFibo draws a box between a start and end time, then calculates Fibonacci lines from the high and low inside that box. The default uses midnight to 09:00 with 50%, 100%, and 200% levels.
Additional lines can be added, and familiar ratios such as 38.2% or 61.8% can be selected from the inputs. The tool is a measurement aid whose result depends on the chosen window.
How to use P4L BoxFibo
Apply P4L BoxFibo to an MT4 chart and choose the start and end times that define the price box you want to measure.
Adjust the Fibonacci ratios, line count, colors, and style settings to keep only the levels relevant to the selected session or range.
Where it helps
Uses a clearly defined start and end period rather than an unspecified history window.
Allows additional Fibonacci lines and alternative ratios to be added.
Builds the levels directly from the selected box extremes.
