Range Coach suggests ±4%
Stable pairs usually mean-revert; a tight ±4% band captures fees without parking idle capital far from price.

After fees, expected IL, and gas, this range nets about 27.1% annualized under your shock assumption.
Assumptions
Fees from seed 24h volume ÷ TVL × a concentration boost. IL from a ±move over the horizon. Gas = mint + exit.

How the numbers work
Is this live pool data?
Pool Explorer and Calc prefer near-live DefiLlama yields (TVL, 24h volume, fee APR) plus coin prices, cached ~20 minutes in D1. If the fetch fails, we fall back to labeled seed tables — never silent fake “live.” Deposit sizing is still planning math, not an executable quote or wallet write.
What does the Net Yield Truth Label include?
Your fees (24h volume × fee tier ÷ TVL, boosted for how concentrated your range is), minus IL drag (classic impermanent loss for your expected ± move, annualized over the horizon), minus gas drag (your mint + exit gas, annualized). It is a planning estimate, not a guaranteed return.
Do I need a wallet to use Calc?
No. Nothing on DefiLPKit connects to or signs with your wallet. Saving a scenario stores it against an anonymous cookie session — we never request token approvals or custody funds.
How does Range Coach pick a width?
Coach maps the pair’s volatility bucket (stable / blue-chip / volatile) to a suggested ± band around the current price. It is the default range; edit min or max to go custom.
What is Range Studio’s historical backtest?
Range Studio estimates how often free CEX hourly closes (Coinbase → Kraken → Binance public APIs) stayed inside your band over 7/14/30 days. It shows % in-range, a stricter full-bar metric, and rough fee×time-in-range vs classic IL. Candles are CEX proxies — not Uniswap ticks or exact LVR. Results are labeled estimates; source + window are always shown.
