Friends I could see no premiums are going down easily! It's stucked. I expect premium will erode huge if there is no surprise news from the budget! So making long strangle may not work in this case. Mostly our following strategy will work if there is no big surprise news.
So take only risky traders the following:
Short straddle:
Sell BNF 32200CE & 30700PE at 120-121
SL 145 TGT 105 90 80!
