Banknifty descending triangle

Updated
If it breaks level mentioned then we can see 400 points down move. Lets see if Monday holds it. My analysis is on 15 min chart and only for educational purpose. Please don't trade but just observe if this chart pattern works.
Note
Looks like it is not going to break , this analysis may not hold good given gap up opening.
