a. Time Zone 1 (TZ-n) is the starting TZ and is defined in decimal minutes, i.e., 0.5 = 30 seconds, etc.
b. A user defined increment, also in decimal minutes, is added to TZ-1 to create TZ-2. The same increment is added to TZ-2 to create TZ-3. TZ-4 is anything above TZ-3. Lines are produce for TZ-1 to 3. The HTF-like “zone” is a sub period of TZ-1 and is identified when the bar time is LT or EQ to a user define number of seconds. If the bar time is below the defined time it could be considered potential HFT activity
c. An optional histogram of TZ1-TZ4 times is produced, with each zone having a user defined color.
