Above 18000! Will it sustain or not?

We are up to the 2nd week of expiry and the nifty is above 18000. On Monday, Nifty opened with a gap up and gave a good up move and closed just above 18,000. Today it sustained the 18000 consolidation between 100 points. It's encouraging to see that more bull runs or breaks below 18,000 are on the way. Because we know there is a lot of data on the way, we can expect a move accordingly. I do think overnight aggressive positioning is a good idea. We have an important line to watch above 18200. Well, below 17900, I kept a close look at the lines and today 18020 was respected. Let's see where it opens tomorrow.
When it comes to my weekly option selling, I have 17600 PE and 18350 PE. I entered an intraday short straddle on Monday now that it is bright and sunny. I already have my overall P & L in nearly 1% red this month, so I'm not confident about carrying it till Thursday. I hope to exit at 0.5%+Tomorrow, planning to take a fresh entry on Thursday to end up flat this week. I am excited to see where Nifty opens on Thursday.
