I have an indicator that plots lines ahead of Forex price action for the previous day's OLHC. This works well, but come Friday it strangely disappears. I'm wondering if the time calculation is affected by the forthcoming weekend (market close). However, I've been scratching my head to determine the precise cause. Any help would be greatly appreciated.
