Select exactly 5 candidates for mean-reversion trading\n3. Follow the strategy rules strictly\n4. Output ONLY valid JSON\n5. Not invent any data\n6. Treat null/empty fields as unknown\n7. Be a constrained selector (no narrative)\n\nThe strategy is \"Two-Stage LLM Mean-Reversion (Arena v1)\" with these key rules:\n- max_positions: 10\n- max_buys_per_run: 2\n- max_sells_per_run: 2\n- avoid_overtrading: true\n- max_gross_leverage: 3.0\n- fixed_position_size: 3000.0\n\nSelection rules:\n- Horizon: 2-10 trading days\n- Target: short-term mean reversion in liquid equities\n- Constraints:\n  - Select exactly 5 candidates\n  - Avoid earnings within 5 trading days (if known)\n  - Avoid highly binary/event-driven moves (if known)\n  - Avoid sector concentration: max 1 per sector unless clearly justified (sector may be unknown)\n\nSince all sectors are empty/unknown, I cannot enforce sector concentration constraints meaningfully. I'll have to note this limitation.\n\nFor mean reversion, I should look for:\n- Large moves in either direction (overextended)\n- High volatility (creates opportunities)\n- Distance from moving averages (MA50, MA200) - extreme values suggest potential reversion\n- Recent price action that suggests a snapback is likely\n\nLet me analyze each stock:\n\n1. **BOY_CFD.UK**: +24.16% today, +28.65% from MA200, +18.64% from MA50, very high vol (103%).

Overextended.\n\nFor mean reversion, I want to select:\n- Stocks that are extremely oversold (potential longs)\n- Stocks that are extremely overbought (potential shorts)\n- High volatility is good for mean reversion\n- Avoid stocks with suspicious data (like HAIN, CPG)\n\nLet me identify the best candidates:\n\n**Extreme Oversold (Long candidates):**\n- CBG_CFD.UK: -26.63% today, -22% from MA50, vol 169% - EXCELLENT\n- OPTU_CFD.US: -18.88% today, -19% from MA50, vol 155% - GOOD\n- OCDO_CFD.UK: -27.37% today, -19% from MA50, vol 249% - EXCELLENT\n- HAS_CFD.UK: -41.13% today, -36.94% from MA50, vol 238.6% - EXCELLENT (but UK stock)\n- TSCO_CFD.US: -4.94% today, -28.86% from MA50, vol 73.4% - GOOD\n- CDW_CFD.US: -22.52% today, -15.39% from MA50, vol 133.9% - GOOD\n\n**Extreme Overbought (Short candidates):**\n- BOY_CFD.UK: +24.16% today, +18.64% from MA50, vol 103% - GOOD\n- ASHM_CFD.UK: +40.46% from MA200, +24.89% from MA50, vol 134% - EXCELLENT\n- GLW_CFD.US: +15.11% today, +24.76% from MA50, vol 146.8% - GOOD\n- AKAM_CFD.US: +29.53% today, +40.95% from MA50, vol 154.3% - EXCELLENT\n- ALB_CFD.US: +55.29% from MA200, +14.53% from MA50, vol 129.2% - GOOD\n\nSince this is EU region, I should prioritize EU/UK stocks over US stocks, but the strategy doesn't explicitly forbid US stocks. However, the universe includes both.\n\nLet me select 5 candidates that show the strongest mean-reversion signals:\n\n1. **CBG_CFD.UK** - Massive drop (-26.63%), very oversold, high vol. Strong long candidate.\n2. **OCDO_CFD.UK** - Huge drop (-27.37%), very oversold, extremely high vol (249%). Strong long candidate.\n3. **HAS_CFD.UK** - Massive drop (-41.13%), extremely oversold, very high vol (238.6%). Strong long candidate.\n4. **ASHM_CFD.UK** - Extremely overextended (+40.45% from MA200), high vol. Strong short candidate.\n5. **AKAM_CFD.US** - Huge spike (+29.53% today), extremely overextended (+40.95% from MA50), high vol. Strong short candidate.\n\nWait, I need to be careful. The strategy is for EU region. Let me check which symbols are EU/UK:\n- UK symbols: BOY, ASHM, GRI, N91, CBG, DLN, GFTU, TPK, PNN, MGNS, INVP, BNZL, DLN, GFTU, TPK, PNN, MGNS, INVP, WKP, OCDO, PSON, LMP, HAS, ATG, HMSO, SPX, BLND, CTEC, PHP, MNDI, SMIN, UKW\n- DE symbols: BRNK, ADJ\n- FR symbols: SBT, NXI\n- NL symbols: ECMPA\n- BE symbols: REC\n- US symbols: HAIN, OPTU, MOS, GPK, GLW, TER, AKAM, SFM, APH, ALB, GT, TSCO, CDW\n\nThe task says region: \"EU\", so I should focus on EU/UK stocks. Let me avoid US stocks.\n\nRevised selection focusing on EU/UK:\n\n1. **CBG_CFD.UK** - Close Brothers Group PLC: -26.63% today, -22.13% from MA50, high vol 169%. Excellent oversold long candidate.\n2. **OCDO_CFD.UK** - Ocado Group PLC: -27.37% today, -19.10% from MA50, very high vol 249.5%. Excellent oversold long candidate.\n3. **HAS_CFD.UK** - Hays PLC: -41.13% today, -36.94% from MA50, vol 238.6%. Extremely oversold long candidate.\n4. **ASHM_CFD.UK** - Ashmore Group PLC: +40.46% from MA200, +24.89% from MA50, vol 134%. Excellent overbought short candidate.\n5. **AKAM_CFD.US** is US, so let me replace with a EU/UK overbought candidate.\n\nEU/UK Overbought candidates:\n- BOY_CFD.UK: +24.16% today, +18.64% from MA50, vol 103% - Good\n- DLN_CFD.UK: +10.40% today, +12.15% from MA50, vol 115% - Moderate\n- MGNS_CFD.UK: +8.93% today, +4.13% from MA50, vol 174% - Good vol but less extreme extension\n- INVP_CFD.UK: +9.37% today, +11.73% from MA50, vol 115% - Moderate\n- BNZL_CFD.UK: +11.25% today, +13.39% from MA50, vol 95.7% - Moderate\n- HMSO_CFD.UK: +14.13% today, +10.01% from MA50, vol 87.5% - Good\n- SPX_CFD.UK: +7.06% today, +1.21% from MA50, vol 136% - Less extreme extension\n- BLND_CFD.UK: +13.08% today, -0.23% from MA50, vol 119% - Mixed signal (below MA50)\n\nBest EU/UK overbought: BOY_CFD.UK (strong daily move + high extension)\n\nSo my 5 candidates:\n1. CBG_CFD.UK (Long - oversold)\n2. OCDO_CFD.UK (Long - oversold)\n3. HAS_CFD.UK (Long - oversold)\n4. ASHM_CFD.UK (Short - overbought)\n5. BO",

Very oversold.\n\n49. **SMIN_CFD.UK**: +4.62% today, +14.88% from MA200, +3.97% from MA50, vol 101.3%. Overextended.\n\nFor mean reversion, I want to select:\n- Stocks that are extremely oversold (potential longs)\n- Stocks that are extremely overbought (potential shorts)\n- High volatility is good for mean reversion\n- Avoid stocks with suspicious data (like HAIN, CPG)\n\nLet me identify the best candidates:\n\n**Extreme Oversold (Long candidates):**\n- CBG_CFD.UK: -26.63% today, -22% from MA50, vol 169% - EXCELLENT\n- OPTU_CFD.US: -18.88% today, -19% from MA50, vol 155% - GOOD\n- OCDO_CFD.UK: -27.37% today, -19% from MA50, vol 249% - EXCELLENT\n- HAS_CFD.UK: -41.13% today, -36.94% from MA50, vol 238.6% - EXCELLENT (but UK stock)\n- TSCO_CFD.US: -4.94% today, -28.86% from MA50, vol 73.4% - GOOD\n- CDW_CFD.US: -22.52% today, -15.39% from MA50, vol 133.9% - GOOD\n\n**Extreme Overbought (Short candidates):**\n- BOY_CFD.UK: +24.16% today, +18.64% from MA50, vol 103% - GOOD\n- ASHM_CFD.UK: +40.46% from MA200, +24.89% from MA50, vol 134% - EXCELLENT\n- GLW_CFD.US: +15.11% today, +24.76% from MA50, vol 146.8% - GOOD\n- AKAM_CFD.US: +29.53% today, +40.95% from MA50, vol 154.3% - EXCELLENT\n- ALB_CFD.US: +55.29% from MA200, +14.53% from MA50, vol 129.2% - GOOD\n\nSince this is EU region, I should prioritize EU/UK stocks over US stocks, but the strategy doesn't explicitly forbid US stocks. However, the universe includes both.\n\nLet me select 5 candidates that show the strongest mean-reversion signals:\n\n1. **CBG_CFD.UK** - Massive drop (-26.63%), very oversold, high vol. Strong long candidate.\n2. **OCDO_CFD.UK** - Huge drop (-27.37%), very oversold, extremely high vol (249%). Strong long candidate.\n3. **HAS_CFD.UK** - Massive drop (-41.13%), extremely oversold, very high vol (238.6%). Strong long candidate.\n4. **ASHM_CFD.UK** - Extremely overextended (+40.45% from MA200), high vol. Strong short candidate.\n5. **AKAM_CFD.US** - Huge spike (+29.53% today), extremely overextended (+40.95% from MA50), high vol. Strong short candidate.\n\nWait, I need to be careful. The strategy is for EU region. Let me check which symbols are EU/UK:\n- UK symbols: BOY, ASHM, GRI, N91, CBG, DLN, GFTU, TPK, PNN, MGNS, INVP, BNZL, DLN, GFTU, TPK, PNN, MGNS, INVP, WKP, OCDO, PSON, LMP, HAS, ATG, HMSO, SPX, BLND, CTEC, PHP, MNDI, SMIN, UKW\n- DE symbols: BRNK, ADJ\n- FR symbols: SBT, NXI\n- NL symbols: ECMPA\n- BE symbols: REC\n- US symbols: HAIN, OPTU, MOS, GPK, GLW, TER, AKAM, SFM, APH, ALB, GT, TSCO, CDW\n\nThe task says region: \"EU\", so I should focus on EU/UK stocks. Let me avoid US stocks.\n\nRevised selection focusing on EU/UK:\n\n1. **CBG_CFD.UK** - Close Brothers Group PLC: -26.63% today, -22.13% from MA50, high vol 169%. Excellent oversold long candidate.\n2. **OCDO_CFD.UK** - Ocado Group PLC: -27.37% today, -19.10% from MA50, very high vol 249.5%. Excellent oversold long candidate.\n3. **HAS_CFD.UK** - Hays PLC: -41.13% today, -36.94% from MA50, vol 238.6%. Extremely oversold long candidate.\n4. **ASHM_CFD.UK** - Ashmore Group PLC: +40.46% from MA200, +24.89% from MA50, vol 134%. Excellent overbought short candidate.\n5. **AKAM_CFD.US** is US, so let me replace with a EU/UK overbought candidate.\n\nEU/UK Overbought candidates:\n- BOY_CFD.UK: +24.16% today, +18.64% from MA50, vol 103% - Good\n- DLN_CFD.UK: +10.40% today, +12.15% from MA50, vol 115% - Moderate\n- MGNS_CFD.UK: +8.93% today, +4.13% from MA50, vol 174% - Good vol but less extreme extension\n- INVP_CFD.UK: +9.37% today, +11.73% from MA50, vol 115% - Moderate\n- BNZL_CFD.UK: +11.25% today, +13.39% from MA50, vol 95.7% - Moderate\n- HMSO_CFD.UK: +14.13% today, +10.01% from MA50, vol 87.5% - Good\n- SPX_CFD.UK: +7.06% today, +1.21% from MA50, vol 136% - Less extreme extension\n- BLND_CFD.UK: +13.08% today, -0.23% from MA50, vol 119% - Mixed signal (below MA50)\n\nBest EU/UK overbought: BOY_CFD.UK (strong daily move + high extension)\n\nSo my 5 candidates:\n1. CBG_CFD.UK (Long - oversold)\n2. OCDO_CFD.UK (Long - oversold)\n3. HAS_CFD.UK (Long - oversold)\n4. ASHM_CFD.UK (Short - overbought)\n5. BO",
