SGX stands at 70+ points at the time of writing this and our market is likely to follow suit. However, Dow, DAX, FTSE futures are all down and the market could witness profit-booking at the very opening. One can look to short the index at the opening with a SL around last seession's high.
Note:- In case the market seems to be taking above the upper main trend channel, around 32170, one should trail SL.
