The world of cryptocurrency trading is evolving rapidly, and artificial intelligence (AI) is at the forefront of this transformation. Traders and researchers alike are turning to machine learning models—particularly neural networks—to forecast price movements and design profitable trading strategies. This article explores how a neural network-based algorithm can be used to predict cryptocurrency price trends and generate consistent returns, based on a comprehensive research study that leverages historical data and advanced modeling techniques.
Understanding Algorithmic Trading in Crypto Markets
Algorithmic trading uses predefined rules executed by computer programs to automate trade decisions. In high-volatility environments like the cryptocurrency market, such systems offer speed, precision, and emotional detachment—key advantages over manual trading.
This approach becomes even more powerful when combined with AI models capable of identifying complex patterns in vast datasets. The core objective? To develop a reliable and profitable model that predicts future price directions of digital assets using publicly available historical data.

Data Collection and Feature Engineering
A robust predictive model starts with high-quality data. The study analyzed a dataset comprising 402 cryptocurrencies, all paired against the USDT stablecoin, with OHLC (Open-High-Low-Close) and volume data collected at 4-hour intervals. After preprocessing, this yielded approximately 1.5 million data samples—a substantial foundation for training.
Key Features Used in the Model
To enable accurate classification, the researchers extracted 36 meaningful features, including:
- Technical indicators: RSI (Relative Strength Index), ULTOSC (Ultimate Oscillator)
- Volatility measures: Bollinger Bands
- Trend signals: EMA (Exponential Moving Average) crossovers
- Price change metrics: Percentage change in closing prices, Z-Score
- Temporal data: Time-based patterns such as day-of-week or session trends
These features allow the model to detect subtle market behaviors that may precede significant price moves.
Labeling Strategy: Turning Prediction into Action
Instead of predicting exact prices (a regression task), the problem was framed as a classification challenge with three actionable labels:
- Buy
- Sell
- Hold
This simplifies decision-making and aligns directly with real-world trading actions.
The labeling algorithm uses two threshold parameters, α (alpha) and β (beta):
- α is set at the 85th percentile of historical price changes
- β is set at the 99.7th percentile
These thresholds help filter out noise and extreme outliers. If expected returns fall below α or exceed β, the label defaults to "Hold," reducing false signals during volatile or stagnant periods.
The Neural Network Architecture: Multi-Layer Perceptron (MLP)
The chosen model is a Multi-Layer Perceptron (MLP)—a type of feedforward neural network. It consists of:
- An input layer (36 neurons for each feature)
- Two hidden layers (128 and 64 neurons respectively)
- An output layer with 3 neurons (Buy/Sell/Hold)
The architecture was optimized through iterative testing to balance performance on both training and test sets, avoiding overfitting without relying on dropout or regularization techniques.
Grid search was employed to determine optimal window sizes for input sequences—balancing short-term responsiveness with long-term trend recognition.
Model Comparison and Performance
Several models were evaluated:
- XGBoost
- Logistic Regression (Logit)
- Stochastic Gradient Descent (SGDLinear)
While XGBoost performed well, the MLP outperformed all others in accuracy and consistency across multiple market conditions—especially in distinguishing between sideways, bullish, and bearish phases.
Backtesting: Validating Strategy Profitability
Accuracy alone isn’t enough; profitability matters most. The top-performing models were subjected to rigorous backtesting across Bitcoin, Ethereum, and Algorand.
Key Findings from Backtests
- The model demonstrated strong generalization, performing well across different cryptocurrencies.
- Long-term backtests showed particularly strong returns on Ethereum.
- During market crashes (e.g., TerraLuna, FTX collapse), the MLP-based strategy exhibited smoother drawdowns compared to naive benchmarks.
- A protective stop-loss mechanism further enhanced risk management.
Notably, the model operates with relatively low trade frequency, making it suitable for traders seeking sustainable gains without excessive transaction costs.
Feature Importance Analysis Using SHAP
Understanding why a model makes a decision is crucial. Using SHAP (SHapley Additive exPlanations), researchers identified the most influential features:
✅ Top-performing features:
- Technical indicators
- EMA crossovers
- Time-based signals
❌ Less effective:
- Candlestick patterns (showed limited predictive power)
This insight helps refine future models by focusing on high-signal inputs.

Comparison with Existing Research
The study benchmarks its results against five recent papers using similar methodologies. Key differentiators include:
- Use of three-class labeling vs. binary (up/down)
- Focus on profitability rather than pure accuracy
- Inclusion of transaction fees in performance calculations
- Testing across diverse market cycles
Despite lower trading frequency, the proposed MLP strategy achieved competitive or superior ROI compared to high-frequency alternatives—some of which turned unprofitable after accounting for fees.
For example:
- One LSTM-based model reported 115% ROI but incurred 258% losses after 0.3% fees
- Our model maintained profitability under realistic cost assumptions

Frequently Asked Questions (FAQ)
Q: Can neural networks reliably predict cryptocurrency prices?
A: While no model guarantees perfect predictions, neural networks like MLP can identify statistically significant patterns in historical data, improving the probability of successful trades when combined with sound risk management.
Q: Is this strategy suitable for beginners?
A: The underlying concept can be understood by beginners, but implementation requires knowledge of Python, machine learning libraries (like TensorFlow/PyTorch), and basic financial data analysis.
Q: How important are transaction fees in algorithmic trading?
A: Extremely. High-frequency strategies often fail because fees erode profits. This model emphasizes lower trade frequency to remain profitable even after costs.
Q: Can this model work outside crypto markets?
A: Yes. With proper adaptation, the framework can be applied to forex, equities, commodities, or indices—any market with sufficient historical data.
Q: What makes this approach better than simple "buy and hold"?
A: Backtests show superior risk-adjusted returns. The model actively avoids downturns and captures upward momentum more efficiently than passive strategies.
Q: Are candlestick patterns useless in AI trading?
A: Not entirely—but in this study, they contributed less than technical indicators or moving averages. Their value may increase when combined with other modalities.
Future Research Directions
Potential enhancements include:
- Incorporating multi-timeframe analysis
- Integrating sentiment from social media or blockchain on-chain data
- Exploring hybrid models (e.g., combining MLP with LSTM)
- Expanding to non-crypto financial instruments
As AI continues to mature, so too will its role in shaping smarter, more adaptive trading systems.
