PaperDesk Crypto
A backtesting and paper-trading sandbox for retail crypto traders that turns a simple strategy description into weeks of simulated Coinbase trades, with a clear, honest equity-curve report.
Retail crypto traders who want to test an EMA or breakout idea on real Coinbase data before risking real capital
- Plain-English strategy description that converts to a backtest without writing code
- Equity curve, drawdown, win-rate, and per-trade log report against real historical Coinbase candles
- Side-by-side comparison of up to three strategies on the same pair and timeframe
- Exportable trade log (CSV) so users can verify every signal and slippage assumption
The trending EMA bot's own README emphasizes paper-by-default as the trust hook — there's a real audience for the verification side of that value proposition.

Proven willingness to pay in this category: Cryptohopper charges $24–129/mo and SaaSworthy notes the average crypto-exchange SaaS plan is ~$17/mo, suggesting retail traders will pay but are price-sensitive with free tiers (Pioneer, simtrade.io free) compressing the floor.Cryptohopper Pricing Explained: All Plans, Costs & Fees (2026) ↗Pricing Insights for Cryptohopper - SaaSworthy ↗
Crypto systematic trading is durable and Coinbase's Advanced Trade API + Python SDK is a stable platform, though standalone backtesters risk being absorbed into broker-native tooling (Coinbase Advanced itself is expanding).Coinbase Advanced Trade API Python SDK - GitHub ↗
Buildable: official Coinbase Advanced Trade Python SDK and public candle data make ingestion straightforward, but realistic execution modeling (fees, slippage, partial fills) and a polished UI are the real effort drivers.Coinbase Advanced Trade API Python SDK - GitHub ↗
