BNB is fighting to break out of the falling channel on top, it is currently struggling with the upper limit of a specific channel, as you can see, breaking out of the downtrend line with the top gave a strong upward signal.
Resistance lines are visible just above the upper border of the downtrend channel, while the next significant resistance levels are $666 and $724.
However, if the price is rejected and we experience declines again, we can see the first support zone from $564 to $544, then we have support at $509, and then the second very strong zone from $486 to $454.
