Hammer pattern in Tfday on the exact support level(and also EMA200) hints that it will probably be a short-term bottom and bounce back to resistance level at 1692 and test 1700. (which is a tough one since it's a resistance level with a round number)
But the island reversal told us that there's a potential change coming on a way.
So SET might bounce back to retest a resistance level as a courtesy of the hammer and then decline again as a favor of Island top.
