As Srinivas said, the section of the article you read was referring to Stop Loss when someone has taken a short position. In your case (of long position), your stop loss would be near the bottom of the bearish candle. The idea is to put the SL below find that support price (bottom of bearish candle), which if broken, would signal reversal of the bullish trend.
Hope it helps…
Cheers!
