Generating Trading Signals

Overview

Multi-indicator signal generation system that analyzes price action using 7 technical indicators and produces composite BUY/SELL signals with confidence scores and risk management levels.

Indicators Used:

• RSI (Relative Strength Index) - Overbought/oversold
• MACD (Moving Average Convergence Divergence) - Trend and momentum
• Bollinger Bands - Mean reversion and volatility
• Trend (SMA 20/50/200 crossovers) - Trend direction
• Volume - Confirmation of moves
• Stochastic Oscillator - Short-term momentum
• ADX (Average Directional Index) - Trend strength

Prerequisites

Install required dependencies:

pip install yfinance pandas numpy

Optional for visualization:

pip install matplotlib

Instructions

Step 1: Quick Signal Scan

Scan multiple assets for trading opportunities:

python {baseDir}/scripts/scanner.py --watchlist crypto_top10 --period 6m

Output shows signal type (STRONG_BUY/BUY/NEUTRAL/SELL/STRONG_SELL) and confidence for each asset.

Step 2: Detailed Signal Analysis

Get full indicator breakdown for a specific symbol:

python {baseDir}/scripts/scanner.py --symbols BTC-USD --detail

Shows each indicator's contribution:

• Individual signal (BUY/SELL/NEUTRAL)
• Indicator value
• Reasoning (e.g., "RSI oversold at 28.5")

Step 3: Filter and Rank Signals

Find the best opportunities:

# Only buy signals with 70%+ confidence
python {baseDir}/scripts/scanner.py --filter buy --min-confidence 70 --rank confidence

# Rank by most bullish
python {baseDir}/scripts/scanner.py --rank bullish

# Save results to JSON
python {baseDir}/scripts/scanner.py --output signals.json

Step 4: Use Custom Watchlists

Available predefined watchlists:

python {baseDir}/scripts/scanner.py --list-watchlists
python {baseDir}/scripts/scanner.py --watchlist crypto_defi

Watchlists: crypto_top10, crypto_defi, crypto_layer2, stocks_tech, etfs_major
