About Gielinor Gains
Welcome to Gielinor Gains
Gielinor Gains is your premier companion for Old School RuneScape (OSRS) Grand Exchange trading. We analyze recent market data from the OSRS Wiki API to identify profitable trading opportunities, helping players of all levels maximize their returns through intelligent, data-driven insights.
Our Mission
We believe that everyone should have access to powerful trading tools. That's why Gielinor Gains is completely free to use, with one optional paid feature - the Planner tool. Our goal is to democratize Grand Exchange trading and help players profit from intelligent market analysis, not subscriptions or paywalls.
How Our Algorithm Works
Our sophisticated scoring algorithm (0-5 scale) analyzes multiple market factors to identify the best trading opportunities:
- Technical Indicators: RSI (Relative Strength Index), ROC (Rate of Change), and MACD for identifying oversold items and momentum shifts
- Trader Activity Analysis: Buy/sell volume balance and market depth to ensure executable trades
- Risk-Adjusted Returns: ROI calculations with volatility adjustments and capital efficiency scoring
- Market Health Metrics: Trading consistency, data completeness, and liquidity assessment
Understanding the Score System
Our scoring system analyzes market conditions and ranks items from highest to lowest opportunity. Currently, scores range from approximately 2.4 to 3.0, with small differences representing significant trading advantages:
Score 2.85-3.0: Top Opportunities
- Best combination of profit potential and execution feasibility
- Strong technical indicators (oversold RSI, negative momentum)
- Healthy market activity with good liquidity
- These items appear at the top of the table
Score 2.7-2.84: Good Opportunities
- Solid profit potential with reasonable execution
- May have slightly higher competition or less ideal timing
- Still worth trading, especially with good capital
Score 2.5-2.69: Average Opportunities
- Moderate profit potential but may require patience
- Could have lower volume or less favorable indicators
- Consider if top-scored items aren't available
Score Below 2.5: Lower Priority
- Limited profit or execution challenges
- May have poor liquidity or unfavorable technical signals
- Better opportunities likely available higher up
Why Small Differences Matter
Even though scores only range from 2.4-3.0, a difference of 0.1 points can mean:
- The difference between RSI 25 (oversold) vs RSI 50 (neutral)
- 10x more daily trading volume for better execution
- Significantly better profit margins after accounting for competition
- More balanced buy/sell activity vs whale-dominated markets
Focus on relative position in the table rather than absolute score values.
Smart Offer Strategy
Gone are the days of guessing buy/sell prices. Our dynamic pricing engine automatically calculates optimal offer prices based on real-time market conditions:
How Prices Are Calculated
Buy Price Formula
Latest Low Price × (1 + Smart Buy Offset)
Offset typically 0.08% - 2% based on market conditions
Sell Price Formula
Latest High Price × (1 - Smart Sell Offset)
Automatically accounts for 2% GE tax in profit calculations
Dynamic Offset Calculation
The system adapts your offer strategy based on multiple factors:
Market Liquidity
- • Ultra-liquid (100K+ vol): ~0.27% spreads
- • Medium liquid (1K-10K vol): ~0.9% spreads
- • Thin markets (<500 vol): ~1.7% spreads
Technical Conditions
- • Oversold (RSI <30): Aggressive buy pricing
- • Overbought (RSI >70): Aggressive sell pricing
- • High momentum: Tighter spreads
- • High volatility: Wider spreads for safety
Why This Matters
- No Guesswork: System automatically finds the sweet spot between profit and execution
- Market Adaptive: Tight spreads for liquid markets, wider spreads for risky ones
- Technical Timing: More aggressive when technical indicators are favorable
- Risk Management: Wider spreads during volatile or uncertain conditions
- Tax Awareness: All profit calculations account for Grand Exchange tax
