1477 could be the high mark - could be wrong - 50% the h1 bar from 200% percent overbought bar low is 100% bar at high mark at 1480 - So only slight pullback level -
I did opt for a complete 5 minute chart swing high phase at 241% which tally`s with 1500 - but then on further calculation Price would serve better off the h1 chart.
So either way will count. But i find the lower end as best valid as the h1 bar could result as being full and count as a trend reversal.
So its best to monitor until you get the break.
