Biosensor currently trading at $1.35. See what i posted "Will it go higher?" on 3 Feb 2012, if u have sold at 1.65 you probably be waiting for another entry. The good news is now this stock is at it's support again!
Now could be a good entry again, however, this will be a counter trend trade. Meaning now the short term trend is down(in fact down quite sharply). SO, if want to enter, go in baby size first( 1/3 normal size), wait for it to turn and wait for the day when price break above previous day high. Stoploss can place at 5% below your entry e,g 1.35 * 0.95 = 1.28
