► This Indicator draws a rectangle around the candlesticks formed during the Pre-opening of the American Session, it provides the minimum, maximum values as well as the difference and draws segments from the highest and the lowest
until the closing of the American Session…

[Properties] Two checkboxes
– “Info” Shows or hides alphanumeric information
– “Segment” Shows or hides the lines (higher / lower)

Two variables used to
– “Alpha” Adjust the transparency of text and lines (0 to 255)
– “Delta” Adjusts the information (above and below) of the rectangle
(to adjust according to the selected asset)
