AUTO is flat.\n    *   **Candidates (New Opportunities):**\n        *   SRP (Score 90): Short candidate (Extreme extension).\n        *   BBY (Score 85): Short candidate (Significant extension).\n        *   ATG (Score 82): Long candidate (Bounce from oversold).\n        *   LIO (Score 78): Long candidate (Reversal from oversold).\n        *   UTG (Score 75): Long candidate (Oversold stabilization).\n\n2.  **Evaluate Current Holdings (Mean Reversion Context):**\n    *   *Strategy Logic:* Mean reversion implies selling winners (or extended losers if shorting) and buying losers (or oversold assets if longing). However, the prompt implies a \"Two-Stage\" strategy, likely looking for entry/exit points based on deviation from moving averages or oscillators.\n    *   *ADBE (US):* -129 PnL. Price 238 vs Avg 249. Down ~4%. Is it oversold enough to hold or buy more? Or cut losses?\n    *   *AUTO (UK):* 0 PnL. Flat.\n    *   *CBG (UK):* -240 PnL. Price 342 vs Avg 372. Down ~8%.\n    *   *CCL (UK):* -175 PnL. Price 1832 vs Avg 1946. Down ~6%.\n    *   *HIK (UK):* -91 PnL. Price 1236 vs Avg 1275. Down ~3%.\n    *   *IWG (UK):* -129 PnL. Price 177 vs Avg 185. Down ~4%.\n    *   *OCDO (UK):* -175 PnL. Price 204 vs Avg 217. Down ~6%.\n    *   *TUI1 (DE):* -205 PnL. Price 6.89 vs Avg 7.40. Down ~7%.\n\n    *   *Analysis:* Almost all active positions are losing money. In a mean reversion strategy, if positions were bought as \"oversold\", and they continue to drop, one might either cut losses (stop loss) or hold for the reversion. Without specific stop-loss rules provided in the prompt text (other than \"avoid overtrading\"), I need to look for opportunities to rotate capital into *better* mean reversion setups provided in the candidates list.\n    *   The candidates list suggests specific *new* setups (SRP, BBY for shorts; ATG, LIO, UTG for longs).\n    *   The current holdings are all long (qty > 0). The candidates include shorts (SRP, BBY) and longs (ATG, LIO, UTG).\n    *   *Constraint Check:* Max positions is 10. Current active is 8. I can add up to 2.\n    *   *Constraint Check:* Max buys/sells per run is 2.\n\n3.  **Evaluate Candidates vs. Current Holdings:**\n    *   *SRP (Score 90):* \"Extreme extension vs MA200 (+39.7%), prime short-term reversion short.\" -> High confidence short.\n    *   *BBY (Score 85):* \"Significant extension vs MA200 (+33.3%), high probability of pullback.\" -> High confidence short.\n    *   *ATG (Score 82):* \"Strong bounce (+12% 1d) from deep oversold (-25% vs MA200).\" -> Momentum entry long.\n    *   *LIO (Score 78):* \"Momentum reversal (+7.8% 1d) from oversold levels.\" -> Momentum entry long.\n    *   *UTG (Score 75):* \"Deeply oversold (-24% vs MA200) showing early stabilization.\" -> Value/Contrarian long.\n\n    *   *Decision:* The strategy is \"Mean Reversion\".\n        *   SRP and BBY are extended -> Short them.\n        *   ATG, LIO, UTG are bouncing from oversold -> Long them.\n        *   Current holdings are mostly down (oversold or just bad trades). If they are just bad trades, I should cut them. If they are mean reversion longs that haven't reverted yet, I might hold or swap.\n        *   Given the high scores of SRP (90) and BBY (85), these look like the best opportunities. However, the current portfolio is 100% Long. Introducing Shorts might be a strategy shift or just part of the \"Two-Stage\" logic (Stage 1: Identify extreme, Stage 2: Execute).\n        *   Let's look at the \"Sell\" candidates from the current portfolio. Which ones are least likely to revert or are dragging the portfolio?\n            *   TUI1 is down ~7%.\n            *   CBG is down ~8%.\n            *   CCL is down ~6%.\n        *   The prompt says \"Avoid overtrading\". If I don't *have* to sell, I shouldn't.\n        *   However, I have 8 positions. Max is 10. I can buy 2.\n        *   The candidates list includes Shorts (SRP, BBY). If I short, I need to sell something to free up margin/capital if I'm at max leverage, or just use available cash. The prompt doesn't give current cash balance, but implies \"fixed_position_size\" of 3000.\n        *   If I add 2 new positions (Long or Short), I go to 10 positions.\n        *   Which candidates are best?\n            *   SRP (90) - Short.\n            *   BBY (85) - Short.\n            *   ATG (82) - Long.\n        *   If I take SRP and BBY (Shorts), I am betting on a pullback.\n        *   If I take ATG and LIO (Longs), I am betting on a bounce.\n        *   The current portfolio is heavily Long and losing. Adding more Longs (ATG, LIO) increases concentration risk in a falling market (implied by portfolio losses). Adding Shorts (SRP, BBY) provides hedging and profit from the extension.\n        *   *However*, usually, in these Arena prompts, if the strategy is \"Mean Reversion\", and candidates are provided, I should prioritize the highest scores.\n        *   SRP (90) and BBY (85) are the highest scores. They are shorts.\n        *   To enter SRP and BBY, I need to sell existing positions to make room if I want to keep leverage in check, or just add them if I have slots. I have 2 slots (8 current -> 10 max).\n        *   So I can BUY SRP and BUY BBY (meaning Short Sell them) without selling existing ones, assuming leverage allows.\n        *   *Wait*, the prompt says \"Max 2 BUY actions per run\". In CFD terms, opening a short is often treated as a \"Buy\" action in the API (Buy to Open Short) or just \"Open Short\". The schema asks for \"buy\" and \"sell\". Usually \"Buy\" = Open Long, \"Sell\" = Close Long or Open Short. Let's assume standard terminology:\n            *   Buy: Open Long.\n            *   Sell: Close Long OR Open Short.\n            *   *Correction*: In many trading APIs, \"Buy\" and \"Sell\" refer to the direction of the trade. If I want to short SRP, I \"Sell\" SRP. If I want to close CBG, I \"Buy\" CBG (to cover).\n            *   *However*, the schema provided in the prompt has keys: \"buy\" (symbol, position_size, reason) and \"sell\" (symbol, reason).\n            *   Usually, \"buy\" implies adding a long position. \"sell\" implies closing a long position.\n            *   What about opening a short? The prompt doesn't explicitly define \"Short\" as a separate key. It has \"buy\" and \"sell\".\n            *   Let's look at the candidates. SRP is \"prime short-term reversion short\". BBY is \"high probability of pullback\".\n            *   If I can only \"buy\" (long) or \"sell\" (close long), I cannot open shorts.\n            *   *Alternative Interpretation*: \"buy\" means \"Enter Position\" (Long) and \"sell\" means \"Exit Position\" (Long). If the strategy allows shorting, it might be implicit in the \"buy\" list with negative size? No, size is \"number (currency amount)\".\n            *   *Likely Interpretation for this specific Arena context*: The strategy is \"Mean Reversion\". Often this means Long Only (buying dips) or Long/Short. Given the candidates explicitly say \"Short\", I should probably treat \"Buy\" as \"Open Long\" and \"Sell\" as \"Open Short\" or \"Close Long\".\n            *   *Re-reading schema*: \"buy\": [{\"symbol\": \"string\", \"position_size\": \"number (currency amount)\", \"reason\": \"string\"}]. \"sell\": [{\"symbol\": \"string\", \"reason\": \"string\"}].\n            *   If I want to short SRP, do I put it in \"buy\" or \"sell\"?\n            *   If I put it in \"sell\", it might be interpreted as closing a position I don't have.\n            *   If I put it in \"buy\", it implies going long.\n            *   *Hypothesis*: The system might handle shorting by putting the symbol in \"sell\" (to open) or \"buy\" (to open short? No).\n            *   *Safe Bet*: The prompt lists candidates with reasons like \"prime short-term reversion short\". If I ignore shorts, I ignore the top 2 candidates. If I assume \"Sell\" list is for *closing* positions, I can't open shorts.\n            *   *Let's look at the \"Buy\" candidates*: ATG, LIO, UTG. These are Long candidates.\n            *   *Let's look at the \"Short\" candidates*: SRP, BBY.\n            *   If I am restricted to Long-only based on the schema (Buy/Sell usually maps to Open Long/Close Long), I should pick ATG and LIO/UTG.\n            *   *However*, \"Mean Reversion\" often implies shorting the overextended.\n            *   Let's check the current portfolio again. It's all Longs.\n            *   If I assume the \"Sell\" action is for *closing* existing positions, and \"Buy\" is for *opening* new Long positions:\n                *   I have 8 positions. Max 10.\n                *   I can Buy 2.\n                *   Candidates: ATG (82), LIO (78), UTG (75).\n                *   SRP (90) and BBY (85) are shorts. If I can't short, I skip them.\n                *   *But*, maybe \"Sell\" in the output schema is for \"Sell to Open\"?\n                *   Let's look at the \"Sell\" schema: `{\"symbol\": \"string\", \"reason\": \"string\"}`. It does *not* have a \"position_size\". This strongly suggests \"Sell\" is for *closing* existing positions (where size is determined by current qty).\n                *   The \"Buy\" schema *has* \"position_size\". This suggests \"Buy\" is for *opening* new positions.\n                *   Therefore, this schema likely supports **Long Only** strategies (or Short Only, but not mixed in this specific schema structure unless \"Buy\" implies direction).\n                *   *Wait*, if \"Buy\" is for opening, and I want to short, I would need a \"Short\" key or a negative size. The schema doesn't show negative size support explicitly (it says \"number\").\n                *   *Conclusion*: The schema provided (`actions: {buy: [...], sell: [...]}`) combined with the lack of a \"short\" key and the \"sell\" list lacking a size field implies:\n                    *   **Buy**: Open Long Position.\n                    *   **Sell**: Close Long Position.\n                *   *Implication*: I cannot open Short positions (SRP, BBY) with this schema. I must filter candidates for Longs only.\n                *   *Long Candidates*: ATG (Score 82), LIO (Score 78), UTG (Score 75).\n                *   *Action*: Buy ATG and LIO (highest scores).\n\n    *   *Alternative Interpretation Check*: Could \"Sell\" be used to open a short? If I put SRP in \"Sell\", the system might try to sell SRP. If I don't own it, it opens a short. But usually, \"Sell\" without size implies \"Sell All/Close\". If I don't own it, it errors. So \"Sell\" is definitely for closing.\n    *   Therefore, I must ignore the Short candidates (SRP, BBY) or assume the strategy is Long-only for this execution context.\n    *   *Wait*, what if I am wrong and \"Buy\" can take a negative size? The prompt says \"position_size\": \"number (currency amount)\". It doesn't forbid negatives. But standard JSON schemas usually specify \"positive number\" if that's the intent.\n    *   *Let's look at the strategy name*: \"Two-Stage LLM Mean-Reversion\". Mean reversion is often long/short.\n    *   *Let's look at the \"Avoid overtrading\" rule*: \"If no clear improvement vs current holdings, output HOLD for everything\".\n    *   *Let's look at the current holdings*: They are all down. The market seems to be trending down or these are bad picks.\n    *   *Let's look at the Long Candidates*:\n        *   ATG: \"Strong bounce (+12% 1d) from deep oversold (-25% vs MA200).\" -> This is a momentum trade *after* the bounce. Mean reversion usually buys *at* the bottom, not after a +12% bounce. However, the score is 82.\n        *   LIO: \"Momentum reversal (+7.8% 1d) from oversold levels.\" -> Similar to ATG.\n        *   UTG: \"Deeply oversold (-24% vs MA200) showing early stabilization (+3.5% 1d).\" -> This looks more like a classic mean reversion entry (buying the dip).\n    *   *Comparing ATG/LIO vs UTG*:\n        *   ATG/LIO have higher scores (82, 78) but imply chasing a 1-day bounce.\n        *   UTG has a lower score (75) but is \"Deeply oversold\" and \"early stabilization\".\n    *   *Comparing to Current Holdings*:\n        *   Current holdings (TUI1, CBG, CCL, etc.) are likely oversold too (hence the losses).\n        *   If I buy ATG/LIO, I am adding to a portfolio of losers with a \"momentum\" flavor.\n        *   If I sell current losers to buy ATG/LIO, I am churning.\n    *   *Let's reconsider the Short candidates*: If I simply cannot short them, I ignore them.\n    *   *Let's reconsider the \"Sell\" list*: I have 8 positions. Max 10. I don't *need* to sell to buy 2.\n    *   *Constraint*: \"Max 2 BUY actions per run\".\n    *   *Constraint*: \"Max 2 SELL actions per run\".\n    *   *Constraint*: \"Avoid overtrading\".\n    *   *Decision*: I will select the top 2 Long candidates based on score, provided they offer a distinct opportunity.\n        *   ATG (82) - Strong bounce.\n        *   LIO (78) - Momentum reversal.\n    *   *Are they better than current holdings?*\n        *   Current holdings are stagnant or dropping. ATG and LIO are moving up (momentum). This might be a \"Stage 2\" trigger (confirmation of reversal).\n        *   I will Buy ATG and LIO.\n    *   *Position Size*: Fixed at 3000.0.\n    *   *Selling*: Do I need to sell anything?\n        *   I have 8 positions. Buying 2 makes 10.\n        *   Are any current positions \"toxic\" or violating risk rules?\n        *   No stop losses triggered in the data.\n        *   \"Avoid overtrading\" -> Don't sell just to sell.\n        *   So, Sell list is empty.\n\n    *   *Refining the \"Short\" issue*: Is it possible the prompt implies I should *sell* existing longs to *short* the new ones?\n        *   If I sell TUI1 (bad performer) and Short SRP (great short setup), that's a valid mean reversion trade.\n        *   But the schema `sell` doesn't have a size. If I put TUI1 in sell, I close the long. If I put SRP in sell... it's ambiguous.\n        *   If I put SRP",

If I want to short SRP, I \"Sell\" SRP. If I want to close CBG, I \"Buy\" CBG (to cover).\n            *   *However*, the schema provided in the prompt has keys: \"buy\" (symbol, position_size, reason) and \"sell\" (symbol, reason).\n            *   Usually, \"buy\" implies adding a long position. \"sell\" implies closing a long position.\n            *   What about opening a short? The prompt doesn't explicitly define \"Short\" as a separate key. It has \"buy\" and \"sell\".\n            *   Let's look at the candidates. SRP is \"prime short-term reversion short\". BBY is \"high probability of pullback\".\n            *   If I can only \"buy\" (long) or \"sell\" (close long), I cannot open shorts.\n            *   *Alternative Interpretation*: \"buy\" means \"Enter Position\" (Long) and \"sell\" means \"Exit Position\" (Long). If the strategy allows shorting, it might be implicit in the \"buy\" list with negative size? No, size is \"number (currency amount)\".\n            *   *Likely Interpretation for this specific Arena context*: The strategy is \"Mean Reversion\". Often this means Long Only (buying dips) or Long/Short. Given the candidates explicitly say \"Short\", I should probably treat \"Buy\" as \"Open Long\" and \"Sell\" as \"Open Short\" or \"Close Long\".\n            *   *Re-reading schema*: \"buy\": [{\"symbol\": \"string\", \"position_size\": \"number (currency amount)\", \"reason\": \"string\"}]. \"sell\": [{\"symbol\": \"string\", \"reason\": \"string\"}].\n            *   If I want to short SRP, do I put it in \"buy\" or \"sell\"?\n            *   If I put it in \"sell\", it might be interpreted as closing a position I don't have.\n            *   If I put it in \"buy\", it implies going long.\n            *   *Hypothesis*: The system might handle shorting by putting the symbol in \"sell\" (to open) or \"buy\" (to open short? No).\n            *   *Safe Bet*: The prompt lists candidates with reasons like \"prime short-term reversion short\". If I ignore shorts, I ignore the top 2 candidates. If I assume \"Sell\" list is for *closing* positions, I can't open shorts.\n            *   *Let's look at the \"Buy\" candidates*: ATG, LIO, UTG. These are Long candidates.\n            *   *Let's look at the \"Short\" candidates*: SRP, BBY.\n            *   If I am restricted to Long-only based on the schema (Buy/Sell usually maps to Open Long/Close Long), I should pick ATG and LIO/UTG.\n            *   *However*, \"Mean Reversion\" often implies shorting the overextended.\n            *   Let's check the current portfolio again. It's all Longs.\n            *   If I assume the \"Sell\" action is for *closing* existing positions, and \"Buy\" is for *opening* new Long positions:\n                *   I have 8 positions. Max 10.\n                *   I can Buy 2.\n                *   Candidates: ATG (82), LIO (78), UTG (75).\n                *   SRP (90) and BBY (85) are shorts. If I can't short, I skip them.\n                *   *But*, maybe \"Sell\" in the output schema is for \"Sell to Open\"?\n                *   Let's look at the \"Sell\" schema: `{\"symbol\": \"string\", \"reason\": \"string\"}`. It does *not* have a \"position_size\". This strongly suggests \"Sell\" is for *closing* existing positions (where size is determined by current qty).\n                *   The \"Buy\" schema *has* \"position_size\". This suggests \"Buy\" is for *opening* new positions.\n                *   Therefore, this schema likely supports **Long Only** strategies (or Short Only, but not mixed in this specific schema structure unless \"Buy\" implies direction).\n                *   *Wait*, if \"Buy\" is for opening, and I want to short, I would need a \"Short\" key or a negative size. The schema doesn't show negative size support explicitly (it says \"number\").\n                *   *Conclusion*: The schema provided (`actions: {buy: [...], sell: [...]}`) combined with the lack of a \"short\" key and the \"sell\" list lacking a size field implies:\n                    *   **Buy**: Open Long Position.\n                    *   **Sell**: Close Long Position.\n                *   *Implication*: I cannot open Short positions (SRP, BBY) with this schema. I must filter candidates for Longs only.\n                *   *Long Candidates*: ATG (Score 82), LIO (Score 78), UTG (Score 75).\n                *   *Action*: Buy ATG and LIO (highest scores).\n\n    *   *Alternative Interpretation Check*: Could \"Sell\" be used to open a short? If I put SRP in \"Sell\", the system might try to sell SRP. If I don't own it, it opens a short. But usually, \"Sell\" without size implies \"Sell All/Close\". If I don't own it, it errors. So \"Sell\" is definitely for closing.\n    *   Therefore, I must ignore the Short candidates (SRP, BBY) or assume the strategy is Long-only for this execution context.\n    *   *Wait*, what if I am wrong and \"Buy\" can take a negative size? The prompt says \"position_size\": \"number (currency amount)\". It doesn't forbid negatives. But standard JSON schemas usually specify \"positive number\" if that's the intent.\n    *   *Let's look at the strategy name*: \"Two-Stage LLM Mean-Reversion\". Mean reversion is often long/short.\n    *   *Let's look at the \"Avoid overtrading\" rule*: \"If no clear improvement vs current holdings, output HOLD for everything\".\n    *   *Let's look at the current holdings*: They are all down. The market seems to be trending down or these are bad picks.\n    *   *Let's look at the Long Candidates*:\n        *   ATG: \"Strong bounce (+12% 1d) from deep oversold (-25% vs MA200).\" -> This is a momentum trade *after* the bounce. Mean reversion usually buys *at* the bottom, not after a +12% bounce. However, the score is 82.\n        *   LIO: \"Momentum reversal (+7.8% 1d) from oversold levels.\" -> Similar to ATG.\n        *   UTG: \"Deeply oversold (-24% vs MA200) showing early stabilization (+3.5% 1d).\" -> This looks more like a classic mean reversion entry (buying the dip).\n    *   *Comparing ATG/LIO vs UTG*:\n        *   ATG/LIO have higher scores (82, 78) but imply chasing a 1-day bounce.\n        *   UTG has a lower score (75) but is \"Deeply oversold\" and \"early stabilization\".\n    *   *Comparing to Current Holdings*:\n        *   Current holdings (TUI1, CBG, CCL, etc.) are likely oversold too (hence the losses).\n        *   If I buy ATG/LIO, I am adding to a portfolio of losers with a \"momentum\" flavor.\n        *   If I sell current losers to buy ATG/LIO, I am churning.\n    *   *Let's reconsider the Short candidates*: If I simply cannot short them, I ignore them.\n    *   *Let's reconsider the \"Sell\" list*: I have 8 positions. Max 10. I don't *need* to sell to buy 2.\n    *   *Constraint*: \"Max 2 BUY actions per run\".\n    *   *Constraint*: \"Max 2 SELL actions per run\".\n    *   *Constraint*: \"Avoid overtrading\".\n    *   *Decision*: I will select the top 2 Long candidates based on score, provided they offer a distinct opportunity.\n        *   ATG (82) - Strong bounce.\n        *   LIO (78) - Momentum reversal.\n    *   *Are they better than current holdings?*\n        *   Current holdings are stagnant or dropping. ATG and LIO are moving up (momentum). This might be a \"Stage 2\" trigger (confirmation of reversal).\n        *   I will Buy ATG and LIO.\n    *   *Position Size*: Fixed at 3000.0.\n    *   *Selling*: Do I need to sell anything?\n        *   I have 8 positions. Buying 2 makes 10.\n        *   Are any current positions \"toxic\" or violating risk rules?\n        *   No stop losses triggered in the data.\n        *   \"Avoid overtrading\" -> Don't sell just to sell.\n        *   So, Sell list is empty.\n\n    *   *Refining the \"Short\" issue*: Is it possible the prompt implies I should *sell* existing longs to *short* the new ones?\n        *   If I sell TUI1 (bad performer) and Short SRP (great short setup), that's a valid mean reversion trade.\n        *   But the schema `sell` doesn't have a size. If I put TUI1 in sell, I close the long. If I put SRP in sell... it's ambiguous.\n        *   If I put SRP",
