BTC broke through a small-scale channel and then hit the midline of a larger channel,

and after encountering resistance above, it pulled back. If it reaches the 73 resistance level again, consider opening a long position.

However, be aware that this area is close to the daily downtrend channel. If a breakout occurs, you can first stop-loss at 73 long position,

and wait for a higher level to go long. If the 705 support holds, consider adding to long positions. If it cannot hold, consider entering at 688-693.

Try to buy at around 675. If it breaks below the ascending channel, stop-loss.
