Let us instead look at the daily price action. See the chart of Bharti (you can click on the chart to get a larger view which will be shown in a new window) .

It is clear that the trend has been up. So, we accept that the trend is up and treat the most recent price action as a correction. Therefore we should look and get ready for a buy set up. This view is supported by the slow stochastic about to come out above 20 and the RSI beginning to stay above 50. Here are some specific suggestions:
1. For Aggressive traders: buy between 820 and 750, with SL at 720.
2. For Traders with moderate risk appetite: buy when Bharti closes above 875 on a daily closing basis. SL at 750.
Once the trade is taken, trailing stop loss should be employed to protect gains if and when the trade becomes profitable.
