Is LetsDoCrypto the Best Free Crypto Pattern Scanner in 2026?
An honest look at what LetsDoCrypto does well, where it has limitations, and how it compares to the alternatives — from a practical trading perspective rather than a marketing one.
Writing an honest assessment of your own platform is difficult, but traders deserve a clear picture of what LetsDoCrypto actually does well and where it genuinely falls short — not a marketing brochure. This review covers both sides, with a practical comparison to the main alternatives in 2026.
What LetsDoCrypto Does Well
The platform has two core tools, and both deliver meaningfully on their specific purpose — pattern scanning at scale and algorithmic historical matching, both at no cost.
The platform has two core tools, and both do their specific jobs well:
Live Scanner: real-time pattern detection at scale. The Live Scanner monitor 500+ USDT perpetual futures pairs on six timeframes and detect 20 chart pattern types algorithmically. This is the primary use case: finding which pairs are currently forming your target pattern without manually checking hundreds of charts. The scanner updates in real time, ranks matches by similarity score, and covers the full range of common patterns.
Pattern Finder: algorithmic historical matching. The Pattern Finder searches 1M+ historical candles using 10 algorithms — DTW, Pearson, Ensemble, K-mer, Euclidean, Cosine, Chebyshev, Manhattan, Spearman, OBV — to find the closest past instances of the current price structure, then shows what actually happened next.
Free with no account required. Both tools are fully free with no sign-up, no email, no payment information. In 2026, most comparable tools are paywalled or require account creation. The no-friction access is a real differentiator.
Where LetsDoCrypto Falls Short
Being honest about limitations is as important as highlighting strengths — these four gaps are genuine, and knowing them helps you build the right complementary workflow.
- No drawing tools or custom indicators — not a charting platform; TradingView remains necessary for chart annotation
- No price alerts or push notifications — the scanner shows what is forming now but does not alert you when new patterns appear
- Coverage limited to USDT perpetual futures — does not cover spot markets, equities, forex, or other asset classes
- No saved searches or watchlists — without login functionality, you cannot save custom filters or recurring searches between sessions
How It Compares to Paid Alternatives
For the specific use cases LetsDoCrypto covers — real-time crypto pattern scanning and algorithmic historical matching — it is competitive with paid tools costing $39–100/month, with honest gaps in trendline automation and multi-asset coverage.
The main paid alternatives for crypto pattern scanning in 2026 start at $39/month (TrendSpider) and go to $100–$500/month for institutional-grade screeners. For the specific use cases LetsDoCrypto covers — real-time pattern scanning across a large number of crypto futures pairs and algorithmic historical matching — the free tool is competitive with paid alternatives that cost significantly more.
Where paid tools have a genuine advantage: TrendSpider's automated trendline detection, backtesting infrastructure, and multi-asset coverage are real capabilities LetsDoCrypto does not replicate. If you trade equities alongside crypto or need rule-based backtesting, a paid tool is worth the cost.
Who Should Use LetsDoCrypto?
LetsDoCrypto is best suited for active crypto futures traders and pattern-based discretionary traders — not for those who need interactive charting, alerts, or multi-asset coverage.
- Active crypto futures traders who want to find the best pattern setup in the entire market rather than manually checking a small number of charts
- Pattern-based discretionary traders who want historical base rates for setups they are considering, without writing code
- Beginners who want to see real patterns forming and resolving in real time as a learning tool, at no cost
- Any trader who wants to supplement their existing TradingView workflow with broader market scanning and historical pattern validation

Frequently Asked Questions
Is LetsDoCrypto completely free?
Yes — both the Live Scanner and the Pattern Finder are completely free with no account required. There is no free tier with limited features and a paid upgrade; the full functionality of both tools is available to every visitor without signing up or entering any payment information.
What exchanges does LetsDoCrypto scan?
LetsDoCrypto scans USDT perpetual futures pairs across major crypto derivatives exchanges, focusing on the most liquid USDT perp markets with sufficient volume and price history to produce meaningful pattern detection and historical matching results. The platform does not currently cover spot markets, coin-margined futures, or non-crypto asset classes.
Does LetsDoCrypto have push notifications or alerts?
No — LetsDoCrypto does not currently offer push notifications or price alerts. The Live Scanner shows patterns forming in real time when you are actively using the platform. For alert-based workflows, TradingView's alert system can complement the scanner: use LetsDoCrypto to identify which pairs to watch, then set TradingView alerts on those specific pairs for the breakout levels.
How many chart patterns does LetsDoCrypto detect?
The Live Scanner detects 20 chart pattern types across 500+ USDT perpetual futures pairs on six timeframes. Patterns include bull and bear flags, falling and rising wedges, ascending and descending triangles, symmetrical triangles, head and shoulders, inverse head and shoulders, double tops, double bottoms, cup and handle, and others. The Pattern Finder uses 10 different algorithms for historical similarity matching.
Who is LetsDoCrypto best suited for?
LetsDoCrypto is best suited for active crypto futures traders who trade based on chart patterns and want to find the best setups across the full market rather than manually monitoring a small number of pairs. It is also well-suited for discretionary traders who want historical data to validate setups before entering, and for beginners learning pattern recognition by seeing real patterns form and resolve in real time. It is not suited for traders who need interactive charting tools, custom indicator development, or multi-asset coverage beyond crypto futures.
