Canonical identity
Network, contract or mint, venue, market type, base, quote, and settlement terms. Symbols are labels, not global IDs.
Altcoin market scanner
Scan markets without turning noise into certainty.
A framework for Solana and Ethereum token screens, technical analysis tools, HFT-style data, liquidity filters, alerts, and reproducible signal definitions.
Signal stack
Identity → data → liquidity → indicator
A result should preserve contract or market identity, event time, source, quality flags, parameters, and enough liquidity context to judge whether the signal is usable.
Scanner architecture
Every result needs four layers of context
Event chronology
Exchange event time, receipt time, processing time, corrections, and late messages. Processing order is not market order.
Liquidity context
Spread, depth, recent trades, venue coverage, slippage, and position-size filters. Volume alone is not execution quality.
Reproducible signal
Input series, interval, lookback, smoothing, warm-up, missing-data policy, and calculation version.
Technical analysis tools
Describe conditions, not guaranteed trades
Moving averages, RSI, momentum, volatility, volume expansion, trend structure, and order-flow features are transformations of historical data. A scanner should state exactly what condition occurred and which parameters produced it. It should not convert a detected pattern into certain future performance.
Ranking should include quality and liquidity. A dramatic move in a barely traded pair can outrank a liquid market when a system sorts only by percentage change. Add minimum depth, trade count, freshness, venue coverage, and outlier controls first.
Signal record
- Instrument and venue identity
- Source series and candle definition
- Event and publication timestamps
- Indicator parameters and version
- Liquidity and quality filters
- Observed condition and invalidation rule
HFT and high-rate data
Fast feeds require stricter time and correction rules
High-frequency altcoin analytics introduce clock drift, sequence gaps, duplicate messages, out-of-order events, exchange corrections, and uneven venue latency.
Multiple timestamps
Return exchange, receipt, and processing times. Document precision, timezone, and clock synchronization limits.
Snapshot consistency
Use deterministic cursors and event boundaries so pagination does not skip or duplicate changing markets.
Correction policy
Version revised candles or expose revision metadata. A backtest is not reproducible when bars change silently.
A safer scanner workflow
Filter before ranking
Resolve assets
Confirm network, contract, venue, market type, and token metadata.
Validate feed
Check freshness, gaps, sample count, corrections, and mapping confidence.
Apply liquidity
Set spread, depth, slippage, trade count, and venue-coverage thresholds.
Calculate signal
Run a fully specified indicator and retain parameters, version, and context.
Scanner FAQ
Before you trust a signal
What is an altcoin scanner?
A scanner evaluates a defined market universe against filters or signals such as liquidity, price change, volatility, momentum, volume, or technical indicators.
Can a scanner find the next winning altcoin?
No scanner can guarantee future performance. It can surface conditions for research, but market regime, manipulation, execution cost, project risk, and changing information remain material.
Why is contract identity important?
Different tokens can share a symbol. Chain and contract or mint identity prevent histories and signals from joining to the wrong asset.
What should an alert contain?
Instrument, venue, observed condition, timestamp, source, parameters, liquidity context, quality flags, and a link to evidence.
How do HFT analytics differ from ordinary charts?
High-rate data require sequence handling, multiple timestamps, clock assumptions, correction policies, deterministic snapshots, and tighter resource controls.
Design signals that can be reproduced.
The scanner API guide covers canonical instruments, event time, indicators, liquidity, quality, pagination, and object-level security.
