It has been moving in a bullish parallel channel for past a month and may still see an uptrend in the coming days/weeks but for now it has broken a wedge.
If the market stays bullish we can see an upward movement from here (breakout) , otherwise a downward rally (as follows) : -
Resistance - 1) 678 2) 700 (Strong Resistance)
Support - 1) 644 2) 635 (Strong Support)
DISCLAIMER : I am new at this, learning and have a long way ahead, so trade at your own risk !!!!
