ThreeZones displays the time and sessions in three time zones with the help of colored rectangles. (An extended version of my ThreeClocksMT5 product).

In the upper-left corner of the ThreeZones chart, there are three labels. Label 1 on the left, label 2 in the center, label 3 on the right. By default, label 1 displays JST (UTC 8) (Japanese Standard Time), label 2 displays GMT (UTC 0, Daylight Saving Time) (Greenwich Mean time), label 3 displays New York Time (UTC-5, Daylight Saving Time). To the left of each label, there are buttons that enable or disable the session display using a colored rectangle. The colored rectangle consists of the opening time, closing time, maximum and minimum session price of the given time zone. Please note that sessions are displayed on the H1 timeframe and below.

• GMTOffset1-offset from GMT of the left label.
• UseDST1 — use daylight saving time for the left label.
• GMTOffset2-offset from GMT of the central label.
• UseDST2 — use daylight saving time for the central label.
• GMTOffset3-offset from GMT of the right label.
• UseDST3 — use daylight saving time for the right label.
• ServerOffset — the offset of the MT4 server . Let your broker know if you are not sure about the value of this parameter.
