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

[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)
