Bollinger Bands: One thing to note is that currently, the stock is at the bottom of the band. If it remains in the band, rebounded and crossed the middle line (20dma), it would be better for the stock for possible upside.
Stochastic: Seems like OCBC is firmly heading into the oversold region. Look to see if a crossover happens below the 20%. Crossover under 20% level would signal a good possibility of stock price moving up.
Resistance: $9 can be the so called psychological support/resistance for traders. Currently, it seems to be a resistance. Next level resistance is at $9.23.
