The candle at 18:06, which passed through my confirmation was actually not strong enough. Although I caught another pullback, this one is not as beautiful as the one before.
Obviously the price would get bounced from the trendline. When the big green candle appeared at 18:35, I was ready to get in. However, that candle did not close above my confirmation of entry. I waited for a few minutes and got in at the beginning of 18:39.
This may not be a safe trade as the 18:38 candle closed just a little bit higher than my confirmation...
