The Crypto Base Scanner (CBS) is a powerful signal service rooted in the QFL (Quantitative Fair Value Gap) trading methodology, designed to help traders identify high-probability reversal opportunities in volatile cryptocurrency markets. By detecting key support levels—known as "bases"—and monitoring price behavior around them, CBS delivers actionable trading signals that have demonstrated consistent performance over time.
Whether you're using automated bots or managing trades manually, understanding how CBS works, optimizing your settings, and interpreting monthly performance reports can significantly enhance your trading outcomes. This comprehensive guide breaks down everything you need to know about Altrady’s Crypto Base Scanner—from its foundational principles to advanced configuration strategies.
What Is the Crypto Base Scanner?
The Crypto Base Scanner (CBS) identifies potential buying opportunities when the price of a crypto pair drops below a historically significant support level—a "base"—by a predefined margin known as the median drop. These bases are derived from prior market structure: areas where strong buying pressure emerged after deep corrections.
When price breaks below such a base—especially during panic-driven selloffs—it often triggers rapid rebound momentum due to accumulated demand. The CBS signal is triggered when:
- Price falls below the base
- The drop reaches or exceeds the historical median drop for that pair
- Market conditions meet specific filtering criteria (e.g., volume, success rate)
This strategy has proven effective both for manual traders and bot-assisted execution, offering a disciplined, rules-based approach to contrarian trading.

Historical Evolution of CBS
Originally launched as a standalone product at cryptobasescanner.com, the Crypto Base Scanner was later integrated into Altrady, a multi-exchange trading platform built to empower retail traders with advanced tools. While CBS remains accessible independently, all Altrady subscription plans now include full access to CBS signals.
Altrady also features its own Base Scanner tool, which uses the same underlying algorithms but is tailored for manual or semi-automated trading. Unlike the CBS signals, which are automatically sent to users, the Base Scanner allows traders to visualize bases directly on charts and receive alerts based on customizable thresholds.
These two systems operate independently—settings in one do not affect the other—giving users flexibility whether they prefer automation or hands-on control.
Subscription and Access Options
All Altrady subscriptions provide access to CBS signals for use with integrated trading bots. Additionally, CBS signals are available through third-party platforms like 3Commas Marketplace, though separate payment is required there, and an Altrady subscription does not grant access on 3Commas.
For those interested only in signals without full platform access, a signals-only plan is available via Altrady or CryptoBaseScanner. If you already have an account on cryptobasescanner.com, you can use the same email to create your Altrady login by selecting “Forgot password.”
Performance and Success Rate
CBS maintains a strong track record, with monthly performance summaries published in the CBS Monthly Reports. These reports analyze every signal sent during the month and measure how many reached target profits of +1%, +2%, or +3%. They also evaluate performance with Dollar-Cost Averaging (DCA) strategies applied.
You can filter data by:
- Exchange
- Quote currency
- Algorithm type
- 24-hour trading volume
These filters allow traders to fine-tune their strategies based on real-world results across different market conditions.
How Are Signals Triggered?
A CBS signal is generated when:
- The price breaks below a defined base
- The decline reaches or surpasses the median drop for that trading pair
Additional conditions are met:
- Minimum 1,000 hours of historical data
- Success rate ≥ 50%
- Median drop > 3%
- Drop occurs within expected timeframe
- Minimum 24-hour volume of 0.25 BTC
These criteria help ensure signal reliability and reduce false positives in low-quality markets.
Why Signal Frequency Varies
Signal frequency depends heavily on broader market dynamics:
- Stablecoin pairs (e.g., USDT) tend to drop when BTC/USD falls sharply, triggering altcoin panic selling.
- BTC pairs fall when BTC rises in value (since fewer BTC are needed to buy alts), or during major BTC sell-offs.
- Altcoin quote pairs (e.g., ETH, BNB) behave more unpredictably, influenced by both BTC correlation and individual project news.
During high-volatility periods—like bull runs or market crashes—signal frequency increases significantly. Conversely, in sideways markets, fewer signals are generated.
Optimizing Bot Settings for Maximum Efficiency
To get the most out of CBS signals, proper bot configuration is essential. Below are key settings every trader should understand.
Position Size and Number of Concurrent Positions
Balancing position size and concurrent trades is crucial for risk management:
- More positions = lower individual risk per trade
- Fewer positions = higher capital allocation per trade, increasing exposure
For example:
- With 2 concurrent positions at 40% each, a 50% crash results in a 20% account loss
- With 1 position at 80%, the same crash causes a 40% loss
It’s wise to keep 20–50% of funds unallocated for emergency DCAs or manual rescues.
Percentage vs. Fixed Amount Position Sizing
Using percentage-based sizing allows your position size to grow with your account balance automatically. However, rapid profit growth can lead to oversized trades in illiquid markets unless minimum volume rules are adjusted accordingly.
Some bots calculate position size based on available funds only; others include invested funds. Know which model your bot uses to avoid miscalculations.

Minimum Order Size Considerations
Exchanges enforce minimum order values (e.g., $10 for USDT pairs on Binance). Due to tick size rounding, placing orders exactly at the minimum often leads to rejections.
Best practice: Set your minimum order size slightly above exchange thresholds to ensure execution. For low-sat pairs like REP/BTC, even small rounding differences can push orders below acceptable limits.
Minimum Volume Requirements
Liquidity matters. To avoid being stuck holding illiquid coins:
- Aim for 100x your position size in hourly volume
- For safety, consider 200x–500x, especially in volatile or micro-cap markets
However, overly strict volume filters may exclude potentially profitable low-cap opportunities.
Choosing the Right Quote Currency
Your quote currency impacts:
- Signal frequency
- Profitability in fiat terms
- Recovery speed after drawdowns
For instance:
- BTC pairs generate more signals when BTC rallies but may recover slowly
- Stablecoins (USDT, BUSD) react strongly to BTC dips and typically rebound faster
Use monthly reports to compare win rates across quote currencies on your preferred exchange.
Managing Base Currencies and Blacklists
Certain markets should be excluded:
- Leveraged tokens (e.g., ETHDOWN) are inherently risky and excluded from CBS signals
- Low-sat pairs may suffer from long fill times—use price filters or entry time limits to avoid delays
- Delisted or news-sensitive coins pose sudden downside risks
While Altrady blocks known delisted pairs, unexpected crashes still occur. Mitigation strategies include:
- Deep stop-losses
- Smaller position sizes
- Reserving funds for rescues
- Using tight take-profit levels
A/B Testing Your Strategy
Most bots support A/B testing, allowing side-by-side comparison of different DCA levels, stop-loss placements, or concurrency settings. Test across diverse market phases (bull, bear, sideways) to avoid overfitting to short-term patterns.
Remember: The perfect is the enemy of the good. A robust strategy performs well across conditions—not perfectly in one.
Handling Failed Trades: The Rescue Process
No system achieves 100% success. When a trade fails to recover despite DCAs, intervention may be necessary.
Simple Rescues
Add an extra DCA at a lower level to reduce average entry price. Timing matters—wait for signs of stabilization before adding more funds.
Advanced Rescues
If no funds remain for DCA:
- Sell part of your position at a loss
- Rebuy lower to reduce break-even price
- Repeat until recovery becomes feasible
Altrady’s Break Even Calculator helps track your current breakeven point, simplifying rescue decisions.
Market Crashes: Extreme Scenarios
During systemic downturns (e.g., March 2020 “COVID crash”), even strong strategies face prolonged drawdowns. Altcoins often fall harder and recover slower than BTC. In such cases:
- Expect extended holding periods
- Monitor macroeconomic triggers
- Adjust expectations and risk exposure proactively
API Integration for Developers
Programmers can integrate CBS-style signals via Altrady’s public API, available with Trading Plan subscriptions and above for personal use. Commercial applications require direct approval from Altrady support.

Frequently Asked Questions (FAQ)
Q: Can I use CBS signals without a bot?
A: Yes. While bots automate execution, you can manually follow CBS signals using Altrady’s Base Scanner or external alerts.
Q: Are leveraged tokens included in CBS signals?
A: No. All leveraged tokens (e.g., ETHUP, BTCBEAR) are excluded due to their decay and volatility risks.
Q: How often are new signals sent?
A: Frequency varies daily—from zero to dozens—depending on market volatility and your selected filters.
Q: What happens if my order isn’t filled?
A: Fast drops may result in missed fills. Using an entry time limit ensures unfilled orders don’t block future signals.
Q: Should I always use DCA?
A: Not necessarily. While DCAs improve success rates, they increase capital commitment. Use them wisely based on risk appetite.
Q: How accurate are the monthly reports?
A: Reports reflect real signal data with conservative assumptions (e.g., median drop as entry price). They’re updated after positions have time to close fully.
