Personal view on Nifty levels
The short term uptrend, since the low of 2500, is in form of Higher-Low Higher-High (HL HH) pattern, as visible in 30min/60min charts.
After making a new higher high on Friday, SPOT 2923 becomes the key previous HL and a close below SPOT 2923 breaks/stops/reverses the uptrend.
SPOT 2923 is also the 5 Day Swing Low & thus, last week's low.
A close below SPOT 2923 would also mean a re-failure of 50Day Simple Moving Average.
The corresponding FUT level is around 2930, which was the near-low of both Thursday & Friday.
On upside, SPOT 3145-3160 is the key resistance band. A break above confirms the intermediate uptrend.
