Quoting zenophyteDislikedHere is something I use to show the Asian market open.In MT4 if you right click on the chart and select properties.
Go to the common tab and select show grid and select show period separators and apply.
Then when you look at your hourly chart the first candle after the heavy line is open of the Asian market on the chart.
Open of the Eur 7 candles from the heavy line.
open of NY is 13 candles
etc.Ignored
btw, I don't know why MT4 does not allow to switch the chart clock to match your system clock ..
