If your analysis leads you to more profit with AVXL trades then I am very happy for you. I have not found pattern technicals to be that useful for my Biotech trades, especially if binary events are around a corner. I do think price support and resistance lines offer some value in setting my option strike prices (CC and short puts). I will sometimes trade a MACD divergence in larger biotech stocks, especially if I am ok with owning the stock for a while if a short put gets exercised.
