This is purely observational, but today I noticed that Hang Seng futures have risen from a 61.8% Fibonacci level six times this year. And as the rallies have landed anywhere between 6.5% to nearly 50%, it is worth noting that it is trying to rally from it a seventh.
A 3-day bullish reversal pattern formed on Monday (morning star formation) and the daily RSI (2) was oversold on Friday. Bulls could seek dis back towards the 61.8% in anticipation of a leg higher to 20k or 20.5k over the near term.
