Low 3500s look good for long?

Weekly bearish block rejected BTC today and now it's retracing.
Why 3500? 1H and 4H bullish orderblocks and fib support seem aligning there. If we get there, I might take a long. I'll observe for now.

I took some longs before but my original long order never filled. New charts now.
