How are the Nicolas Darvas boxes formed in this tool? This tool looks first for the top, if top is not penetrated for 3 days including that day then it tries to find the bottom. It does the same for bottom, i.e. if bottom is not penetrated for 3 days then bottom is established. Low of the days between top and top+3 is ignored as this is the time when top is getting established. After top and bottom are established it tries to find the breakout. If there is no breakout yet then the color of the box is blue. If breakout is to the up side then color of the box is green, else it is red. You can change box period = 3 to any value.
