Waiting for clear bearish engulfing candle (best when wick also engulfed) and after 1st bearish candle close wait for confirmation with next candle (down wick of 1st bearish engulfed with 2nd bearish) and that's good sign to go short. Take profit on support line (I think it will be also in dynamic support/resistance zone - between 30 and 50 simple moving average). R:R=~2 or better.
