In the recent past the BTC/USD pair is not breaking the line pattern. It is more in the overbought section. But is not going into the oversold section. Even in one instance when it crossed the line pattern, it was just one candle which retracted back up in the next candle.
Partly the reason could be the upcoming fork. The break from the pattern could be confirmed when we get 2 candles below the line (1 partly and 1 full).
