Nifty: Closed below it's Minor Demand Zone

Today Nifty tried to sustain above its minor supply zone @ 9350-9450 but it failed to sustain and in the last hour sell-off it was closed below its next demand zone @ 9100. Now, both levels are resistant for Nifty.
I took a short trade when I got the double confirmation when Nifty rejected the 9350-9450 zone 2nd time.
I carried this trade because today’s below 9100 was not a good closing. Tomorrow I should get a follow throw on the downside.
