Support breached but where would carnage stop on Nifty?

Nifty finally breached 7 months old downside channel towards south which indicates more furious sell-off in coming weeks. Since last few weeks, 15900 was acting as a strong support on the indices but on Friday we have closed below the support indicating more weakness. So were would this carnage end for the bulls? The market always of probabilities in answer and so I have this time too. Checking on Elliot wave, I feel we are into corrective wave C which could end now either at 15450 (considering Wave A=Wave C) or at 14800 (considering Wave C= 123.6% of Wave A). Though chances of taking support at 15450 are little bit brighter because it coincides with other EW guideline which states that corrective WAVE shouldn't trade below motive wave 1's high which is 15431. Please note that its just a guideline and Nifty could even test the second possibility so trade accordingly.

P.S. Sell on rise still considerable for short term traders with SL at 16500.
