it's ok. learn from the mistake. trade with the trend. too many times we look for reversal because we want to get the best possible reversal price. it never happens consistently. losses are a part of the game. as long as you are positive on a longer time horizon, daily loss doesn't matter. the red and blue lines on your chart were acting as support. clue into that if this is the system you follow. purple line was resistance. maybe trail mental stops and ride the wave up. markets do the opposite of what you think, especially when trending. The continuation can continue.
