Time[0]

[flexi]

Hi,

I just tried the modieifed Prior OHLC indicator but it is making small problem.
The point of the modification is when the chart is shoewn in ETH session it will show
the prioir OHLC from start of the RTH session. The problem arise when
the ETH opening is higher then the RTH High. Then as Prior High it prints the High of the first bar of the ETH session. It is the same for the Prior Low. If the ETH opening is bellow the RTH Low, then as Prior Low it prints the Low of the first bar of the ETH session.
I tried to put - 100 and + 100 in the formula bellow to make sure that the High[0] and the Low[0] is always higher/lower but without succes.

currentHigh = Math.Max(currentHigh - 100, High[0]);
currentLow = Math.Min(currentLow + 100, Low[0]);

Any sugestions?


This is the code:
