Hi rajesh,
There were Sell Triggers for the scrips you mentioned. But if you have read my earlier posts about the AFL, you will find there that I have written about certain circumstances when you have to verify the signal by inspecting the charts. If you have seen the charts of ABGSHIP and UNITECH you will find that these are in a trading range. You can see from the charts that, ABGSHIP is still above the previous low where it had taken support. Similarly, UNITECH is on the upmove (making higher lows) which is a factor to be considered before taking the Sell decision. Therefore, it is possible that signal may reverse shortly. Unless they are out of the trading range, you can not obey the trigger. In such cases, just keep a watch on the price movement in coming days and then decide about the trade. That is why I have not included them in the list.
