Step-by-Step Guide

Step 1

Understand What Cash and Carry Actually Pays

Spot-to-futures arbitrage means buying BTC (or ETH) on spot, selling the same amount on futures, and pocketing the funding rate or basis spread when they converge. In early 2024, annualized yields hit 20-40% on Binance during the bull run. As of May 2026, annualized rates on BTC perpetuals sit closer to 8-12% in neutral markets, per Coinglass data.

Step 2

Calculate Your Real Break-Even After Fees

Binance charges 0.1% spot taker + 0.02% futures maker per entry and exit. On a $10,000 position, round-trip fees eat roughly $24 before funding income. You need the funding rate to exceed your fee drag within the holding period — at 0.01% per 8-hour funding interval (the Binance default), that's 0.03% daily, or about $3/day on $10,000.

Step 3

Check Whether the Basis Has Compressed in 2026

The carry trade is crowded. Institutional desks and on-chain delta-neutral vaults like Ethena (which held over $3 billion in open interest as of Q1 2026) compress the spread whenever volatility spikes. Retail can still participate, but you're competing for 8-12% annualized yield against players with sub-millisecond execution.

Step 4

Identify the Specific Risk That Kills Retail Accounts

The trade is not "risk-free." If funding flips negative (shorts pay longs), your position bleeds instead of earns — this happened 11 times on BTC perps in 2025 according to Coinglass historical data. Forced liquidation on the futures leg during a violent spot pump also wipes gains from weeks of carry income in under an hour.

Step 5

Decide Whether to Build the Scanner

A scanner is worth building if you target altcoin perps, not BTC/ETH. Smaller coins like PENDLE, JUP, or new listings frequently show funding rates of 0.1-0.5% per 8 hours (annualized: 109-547%) for 12-72 hour windows, because retail long bias concentrates there. Coinglass and the Binance REST API /fapi/v1/fundingRate endpoint give you this data free, with 8-hour granularity.

Step 6

Build the Minimum Viable Scanner in One Evening

Pull funding rates across all Binance USDT-margined perps using the /fapi/v1/premiumIndex endpoint, filter for annualized rate above 50%, cross-reference spot liquidity (reject pairs with less than $500,000 in 24h spot volume), and alert via Telegram. The edge is not speed — it's catching a high-funding altcoin 30 minutes after listing before the arb crowd arrives. Cash and carry on majors is largely institutional in 2026; on long-tail tokens, retail still has a 2-4 hour window before compression.

Tips and Best Practices

Check funding rates on Binance and Bybit daily because cash-and-carry only works when perpetual funding is consistently positive enough to exceed trading fees and slippage.
Compare spot vs futures basis across multiple expiries on CoinMarketCap derivatives data as of 2026-05 to confirm the spread is wide enough to cover maker fees, which often range from 0.01% to 0.05% per trade.
Track Binance 24h volume spikes since liquidity compression reduces arbitrage fills, and low volume periods often turn theoretical spreads into untradeable noise.
Build a scanner only if you can measure real execution fills from on-chain data from Etherscan and exchange trade logs because paper spreads rarely match filled returns in live markets.
Focus on stablecoin-margined perpetuals like USDT pairs on major exchanges rather than small altcoins because thinner books often show misleading funding rates that collapse during volatility spikes.
