HI St,
I just checked ACC. For me there is no sell or signal yet for the stock. Moreover it can slide down if it closes below 851. The CCI system i check and Stochastic RSI are not giving any signal Yet. Pivot system though suggestes that if it closes below 851, then we can see some downside. Trading above this it can bounce back, as it is standing in the long time support range of 824-855.
Also as you mention that 200 DMA is important, then you might see that it take resistance to go up just neas the 200 EMA and also closed below it, and also just below 20 and 34 EMA. With adverse market condition one can short below 851 only.
