Presenting Results

After a successful analysis response, present the results clearly:

• State the bias prominently (Buy / Sell / Neutral)
• Show Entry, Stop Loss, and Take Profit as formatted prices
• Include the Confirmation Price if provided
• Summarize the analysis narrative in plain language
• Mention credits used so the user stays aware of their balance

Example format:

Entry:              $98,200
Stop Loss:          $95,800
Take Profit:        $103,500

a breakout above $98,500 resistance.
