BTC has broke the trendline support as well as broke the current structure on lower timeframes. This could be the start of a correction to the bottom of the channel.
But considering BTC is bullish on higher timeframes, this could just be a fakeout & consolidation that pushes to new ATHs. Similar to the last push up last week.
As of right now, I am slightly bearish on lower timeframes but waiting for more confirmation before entering any trades. I will look for shorts upon a clear break of the next support around 18275 and then look for longs around 16.5k.
If we get a strong impulse to the upside, I will only look for longs.
