We have put in a higher low as per the ribbon system at 20517.8 (up from earlier low of 20494.6) The last 2 highs were lower highs 20599.9 and 20564.8. Now if we take out 20564.8 with OBV also higher at those levels we can think of going long with sl of 20517.8. But right now the volumes (OBV is not supporting) as when the volumes are not in sync it can lead to a divergence trade.
