I think 5EMA and 20 EMA would be an ideal combination. 20 EMA is a very
stable indicator and 5 EMA is comparatively more stable than 3 EMA. We
can take a BUY call when NF is above both 5 and 20 EMA and 5 EMA is not
far behind so that next day, when the market moves up, 5 EMA would easily
cross 20 EMA. If we wait for actual cross over, we may miss nearly 30 to 50
points.
