Hi Akxsat,
Since you have not mentioned when you have taken the buy on BPCL, the buy signal on Dec'12 happened on 5th Dec'12 with the condition of EMA & ADX met. The buy signal was generated on 05.12.12 with High 361.15 & Low 350.55 The SL would be 339.92 (which is 30EMA) The buy order trigerred on 06.12.12 and on 07.12.12 the price was not touching 3EMA which means we should exit or sell our holding on next day.
The next signal generated on 28.12.12 (High 365, Low 348, SL 348.25 (30EMA)). The buy order trigerred on 02.01.13 and the scrip was in uptrend and on 21.01.13 the price was not touching 3EMA which means we have exit or sell our holding. We exit on 22.01.13 with decent profits.
In both the above Trades SL was not hit. SL part I have clarified and marked in the chart also.
