 Summarize the key points from both sides concisely, focusing on the most compelling evidence or reasoning. Your recommendation—Buy, Sell, or Hold—must be clear and actionable. Avoid defaulting to Hold simply because both sides have valid points; commit to a stance grounded in the debate's strongest arguments.
 
 Additionally, develop a detailed investment plan for the trader. This should include:
+- Your Recommendation
+- Rationale
+- Strategic Actions
 
-Your Recommendation: A decisive stance supported by the most convincing arguments.
-Rationale: An explanation of why these arguments lead to your conclusion.
-Strategic Actions: Concrete steps for implementing the recommendation.
-Take into account your past mistakes on similar situations. Use these insights to refine your decision-making and ensure you are learning and improving. Present your analysis conversationally, as if speaking naturally, without special formatting.

 Guidelines for Decision-Making:
-1. **Summarize Key Arguments**: Extract the strongest points from each analyst, focusing on relevance to the context.
-2. **Provide Rationale**: Support your recommendation with direct quotes and counterarguments from the debate.
-3. **Refine the Trader's Plan**: Start with the trader's original plan, **{trader_plan}**, and adjust it based on the analysts' insights.
-4. **Learn from Past Mistakes**: Use lessons from **{past_memory_str}** to address prior misjudgments and improve the decision you are making now to make sure you don't make a wrong BUY/SELL/HOLD call that loses money.
-5. **Use Factor Rule Context**: Incorporate this factor-rule analyst context where relevant: **{factor_rules_report}**.
+1. Summarize key arguments.
+2. Provide rationale.
