How long have you had the 215-230 range?
I saw I am out of range this morning and seemed quite unlikely to go into the range on the short term (still out of that range now, was briefly in), plus it seemed to play in a tighter range below what I had, and I rebalanced my position in a much tighter range 203-207. So far, so good. I also removed the liquidity from one of my tests yesterday and added it on top of the same range as curve. I didn't nail this one so well, as it moved away from the big bins relatively soon. But if it goes back down and plays at the bottom of that range again, I might earn more fees.
By the way, do you prefer the pool with 0.02% base fee and a higher volume compared to liquidity or the one with 0.10% fee and a lower volume to liquidity? The fees/TVL per 24h were almost identical last time I checked.
I went out quite fast because it dropped under 200 and I didn't believe it would go back immediately.
I tend to go for the lover fees if the ration fees/TVL is similar. I think that bigger fees only are triggered when there is an arbitrage option. So in my opinion smaller fees will get more regular transactions but I'm not 100% sure about that :-).
I chose the one with the smaller fee too. So far it doesn't seem like we are wrong about it.
