Binance futures order book history from 3 nodes, with a public gap log
What it is
What it does
CandleFeed is a small API for crypto derivatives data (funding, open interest, liquidations).
Problem
We wanted to test execution ideas against what the Binance book looked like.
Who pays
traders and developers in the crypto derivatives market
Monetization
$149/mo for the full archive
Competition
the niche may be moderate due to the specific focus on Binance futures order book data
Weaknesses
one venue, 25 symbols (10 with history from June 2026, 15 from late September), we can't backfill what we didn't record, the 100ms stream, not Binance's fastest
What could be built instead
Opportunity
expand to multiple venues and increase the number of symbols recorded
Vertical niche
yes, vertical SaaS for crypto trading analysis
MVP
a basic API that provides real-time access to Binance futures order book data.
Differentiation
data integrity checks and public gap log for reliability
AI opportunity
use AI to provide predictive analytics on trading data
