Fundex
Perpetual futures pay a funding rate, and every exchange quotes it differently. Fundex lines them up honestly, then ranks the spread between exchanges by net return after fees and order-book slippage.

The story
01 · THE PROBLEM
A headline spread isn't a return.
Binance, Delta, CoinDCX, WazirX and CoinSwitch publish funding on different intervals and with different field semantics. Compare them naively and the spread you see is not the spread you'd earn.
02 · THE BUILD
Normalise first, rank second.
Each contract is normalised to its true funding interval. Opportunities are then ranked by net return after fees and slippage computed from the live order book, not by the raw rate gap.
03 · TRUST
Every opportunity is graded.
An 8-point trust score travels with each opportunity, so a stale quote or a shaky data source shows up as a warning instead of an attractive number.
04 · EXECUTION
From signal to paper trade to live.
A paper and live trading engine runs against live order books. A backtester replays history, and a Telegram bot with 20+ commands handles alerts and control. The whole thing is covered by 130+ unit tests.
