buy will be advisable only if price sustain above 142 .as we can see three things on weekly chart
1. trend line resistance - price didn't closed above 140 and hence formed a shooting star
2. fib extension suggest price target and resistance at 138-140
3, long shooting star on weekly CHART (which need a confirmation to validate on next candle i.e next week closing)
so neither i will buy at this point nor i will sell unless it break 135 and close below it.
at the end kindly trade as per ur advisor this is my view and i can b completely wrong.
