Adding a Second Dimension
Using a CombinedScore checks WHAT price levels are being broken. CombinedScore asks: "What's moving fast AND breaking significant multi-timeframe resistance?"

Multi-Timeframe Breakout Detection
The BreakoutScore checks six timeframes: 1 week, 1 month, 2 months, 6 months, 1 year, and 18 months.

Ranking Examples:
Breaking an 18-month high scores approximately 17.7 points, which carries more weight than breaking a 1-month high at 4.0 points.

Volume Confirmation
Volume confirmation is required - breakouts must occur on volume exceeding 80% of the 50-week average to qualify as valid signals.

The Performance Trade-off
Using a CombinedScore methodology may show lower raw returns as the multi-timeframe filter is deliberately conservative. It only selects stocks breaking significant resistance with volume confirmation.

In Reality, this means
(a) Fewer trades overall (more signals filtered out)
(b) Missing some fast movers that haven't broken major levels yet
(c) Prioritising quality over quantity

The advantage
Using a CombinedScore methodology, you'll be buying strength at the moment it breaks through meaningful resistance - the exact point where institutional money often enters and trends accelerate. The trade-off is accepting potentially lower frequency for higher-quality setups.

Fine-Tuning the PositionScore (Ranking)
Think of it like this: A "BlendedScore" is like a momentum scanner showing every stock with strong recent gains - it identifies which stocks are running hot right now. Whereas, a "CombinedScore" is like a breakout scanner that only flags stocks making new 6-month or 18-month highs on expanding volume - it identifies which stocks are not just running hot, but breaking through significant resistance levels that have held them down for months.

In a nutshell
(a) BlendedScore finds the movers.
(b) CombinedScore finds the movers that are also breakers - stocks where accumulated selling pressure has finally been exhausted and new trends may be emerging.

Important Caveat: Data Limitations
When using Norgate Silver data, the "CombinedScore" strategy limits multi-timeframe lookbacks to 18 months maximum to avoid survivorship bias. Checking 2-year, 4-year, or 8-year breakouts in live trading or backtesting, you’d need Norgate Platinum’s comprehensive historical data to ensure accuracy.

Conclusion
There's no "best" PositionScore - only what fits your strategy's objectives. The "BlendedScore" excels at capturing raw momentum, generating more trades for those chasing frequent opportunities. The "CombinedScore", incorporating a multi-timeframe breakout context, prioritises high-quality, reliable trend entries, ideal for traders seeking fewer but stronger setups.

Understanding PositionScore in Amibroker
Let me clarify how PositionScore works in Amibroker and the key difference between exploration and backtest ranking. In a backtest, PositionScore prioritises which positions to buy until capital or position limits are reached. In exploration, SetSortColumns orders the output meeting the "Buy or Sell" filter criteria. The trade selection is up to you, as the exploration analysis report displays all the raw signals.

Exploration vs. Backtesting Ranking
(a) Exploration and backtesting rankings are unrelated. Exploration lists positions meeting the Buy or Sell filter, sorted by SetSortColumns for the correct buy order.
(b) Backtesting as a portfolio manager uses PositionScore to decide which buy signals are executed until limits are hit. All the other signals meeting the buy conditions are not displayed.

Why This Matters
PositionScore drives backtest trade selection, directly impacting performance, while exploration’s SetSortColumns helps you analyse and rank signals in your preferred format. Understanding this ensures you optimise both analysis and execution in the way you wish to trade your strategy.
