1. A horizonal line on chart acted as stiff resistance during 18th April 2016 to 6th June 2016, has now turned into support as shown on the chart.
2. Support line as mentioned in the preceding point also coincides with;
(a). level on Fibo (against rise in price from 9th April 2018 to 1st Oct 2018) and
(b). level on Fibo (against rise in price from 11th Sep 2017 to 1st Oct 2018.
3. drawn on the chart also indicates supports & reversal.
4. has good support near value 40 as observed on the chart but it is witnessed that during recent correction, has not even tested 40 which implies that momentum is still intact.
