a breakout of the previous low? Y/N?

if you look at the chart, the price has fallen below the previous low and has made a new low...BUT...
strange thing normally happen on the day b4/after the exchange date, which fall on the 16th every month...
for new fcpo traders, you might wanna take notes on this...If you are a seasoned trader, most probably you already noticed this...
SO let's see what happen on next Monday
