BHARTIARTL - Taking support on 200EMA

Bharti Airtel taking support on 200EMA, and facing resistance of 100EMA and 20EMA. To me, looks like into a no trading zone as one of the bearish flag like pattern is formed and if it breaks down buy range will be around 510-515 levels. On the other hand if it goes above, a safe entry will be around at 537-540. However, not expecting it to go down as the 200EMA support is one of the strongest support for this so far.
