NSE:RELIANCE has broken down from rising wedge (bearish) in hourly chart convincingly. We should see weakness in the stock for few days and given it's weight in NSE:NIFTY , that also can remain subdued. 2800/2850 should be the target zone on the downside for this and those level should offer support.
On the flip side, 20 day MA is around 2925 which might stop the stock from falling further hence keep an eye on that. If 20 DMA breaks today on closing basis then downside remains open.
