Question for educational purpose

Hello all,

I am spending time on Solscan to learn how to read the ins and outs of the wallet. One of the wallets I am tracking is 5bnPJuLWa97tJh1Gx5Yopo4GWrDnvwrjENM9jkKPy8Zs.

Question:
This wallet has EDSE balance of 3.29 million. However, when I investigated this token and wallet address on dexcreener, I could only find the sell points on the EDSE’s chart and not find the buy points. Why is that?

It’s the same situation on a few other tokens that this wallet holds.
