Nifty moving towards a big drop and start of bearish trend?

What i have observed that whenever Nifty has crossed or got resistance from long time trendline it retrace back, ideally it should behave like that. But due to high momentum in short time retracement can be delayed and that is happening in Nifty right now.

I think the force behind Nifty run is weakening in coming days and fresh drop will start. What do you think about above analysis?
