On time frames like hour 4 the last open bar time is 16:00 right before market closes at 17:00. Then when it reopens the first bar starts at 16:00 again.
On m1 timeframe chart says market closed at 17:00 and reopened at 17:00. Are these bars cut off or something on hour 4 chart? So the price between 16:00 and 17:00 is represented as a 4 hour time period? Then again when market re opens?
So I think I've confirmed this as the High Low values for first h4 bar after latest market open(2014.07.27 16:00) matches those on m1 chart from 17:00 to 20:00.
Mt4 represents ticks from 17:00 to 20:00 as a 4 hour period. As well as every other high time frame.
