HAS_CFD.UK: change_1d_pct: -17.21%, distance_from_ma50_pct: -12.89%, volatility: 117.96%\n\n\n2. THG_CFD.UK shows a significant drop with a 1-day change of -21.46% and a MA50 deviation of -18.65%. Its volatility of 150.53% suggests potential mean reversion opportunity, though the high volatility requires careful analysis.\n\n3. CRST_CFD.UK demonstrates a substantial decline with a 1-day change of -12.82% and a MA50 deviation of -15.85%. The extreme volatility of 236.54% indicates significant market uncertainty.\n\n4. PAGE_CFD.UK presents a dramatic drop with a 1-day change of -36.80% and a MA50 deviation of -31.73%. The high volatility of 193.23% suggests potential mean reversion, but requires thorough investigation.\n\n5. ICG_CFD.UK shows a moderate decline with a 1-day change of -15.19% and a MA50 deviation of -12.26%. Its lower volatility of 73.10% makes it a potentially more stable mean reversion candidate.\n\n6. JDW_CFD.UK indicates a slight negative deviation with a 1-day change of -2.99% and a MA50 deviation of -6.43%. The volatility of 119.52% suggests moderate price movement.\n\n7. SHC_CFD.UK demonstrates minimal deviation with a 1-day change of -2.90% and a MA50 deviation of -0.77%. The low volatility of 63.76% suggests limited price movement.\n\n8. BBY_CFD.UK shows a minimal 1-day change of -1.10% with a MA50 deviation of -1.63%. The extreme volatility of 2239.47% raises concerns about market stability.\n\n9. CCL_CFD.UK presents a moderate decline with a 1-day change of -6.54% and a MA50 deviation of -14.68%. The extremely high volatility of 5150.41% indicates significant market uncertainty.\n\n10. BEN_CFD.FR shows a slight positive deviation with a 1-day change of 1.35% and a MA50 deviation of -11.04%. The extreme volatility of 3786.51% suggests potential market instability.\n\n11. COR_CFD.PT demonstrates a minimal decline with a 1-day change of -0.28% and a MA50 deviation of 4.35%. The volatility of 1420.24% indicates significant price fluctuations.\n\n12. BPOST_CFD.BE shows no 1-day change with a MA50 deviation of 7.00%. The extreme volatility of 2622.86% suggests potential market uncertainty.\n\n13. AAF_CFD.UK presents a slight positive deviation with a 1-day change of 3.21% and a MA50 deviation of 3.71%. The extreme volatility of 3083.52% indicates significant market instability.\n\n**Candidates for SHORT (sell signals - positive deviation from MA50):**\n\n1. MGNS_CFD.UK demonstrates a strong upward movement with a 1-day change of 19.60% and a MA50 deviation of 15.63%. The volatility of 90.39% suggests moderate price fluctuations.\n\n2. JUP_CFD.UK shows a significant upward trend with a 1-day change of 22.07% and a MA50 deviation of 19.27%. The volatility of 96.16% indicates moderate price movement.\n\n3. BOY_CFD.UK presents a strong upward momentum with a 1-day change of 24.16% and a MA50 deviation of 18.64%. The volatility of 103.46% suggests moderate price fluctuations.\n\n4. BME_CFD.UK demonstrates a slight positive deviation with a 1-day change of 1.01% and a MA50 deviation of 7.32%. The extreme volatility of 3503.71% raises concerns about market stability.\n\n5. ATG_CFD.UK shows a minimal positive deviation with a 1-day change of 0.32% and a MA50 deviation of 0.83%. The extreme volatility of 2871.93% indicates significant market uncertainty.\n\n**Long Candidates Analysis:**\n\n1. HAS_CFD.UK: Moderate decline with 17.21% 1-day drop and -12.89% MA50 deviation. Volatility at 117.96% suggests potential mean reversion opportunity.\n\n2. THG_CFD.UK: Significant decline with 21.46% 1-day drop and -18.65% MA50 deviation. Higher volatility of 150.53% indicates increased risk.\n\n3. CRST_CFD.UK: Substantial drop with 12.82% 1-day decline and -15.85% MA50 deviation. Elevated volatility of 236.54% requires careful monitoring.\n\n4. PAGE_CFD.UK: Dramatic decline with 36.80% 1-day drop and -31.73% MA50 deviation. High volatility of 193.23% suggests significant market reaction.\n\n5. ICG_CFD.UK: Moderate decline with 15.19% 1-day drop and -12.26% MA50 deviation.

HAS_CFD.UK: change_1d_pct: -17.21%, distance_from_ma50_pct: -12.89%, volatility: 117.96%\n\n\n2. THG_CFD.UK shows a significant drop with a 1-day change of -21.46% and a MA50 deviation of -18.65%. Its volatility of 150.53% suggests potential mean reversion opportunity, though the high volatility requires careful analysis.\n\n3. CRST_CFD.UK demonstrates a substantial decline with a 1-day change of -12.82% and a MA50 deviation of -15.85%. The extreme volatility of 236.54% indicates significant market uncertainty.\n\n4. PAGE_CFD.UK presents a dramatic drop with a 1-day change of -36.80% and a MA50 deviation of -31.73%. The high volatility of 193.23% suggests potential mean reversion, but requires thorough investigation.\n\n5. ICG_CFD.UK shows a moderate decline with a 1-day change of -15.19% and a MA50 deviation of -12.26%. Its lower volatility of 73.10% makes it a potentially more stable mean reversion candidate.\n\n6. JDW_CFD.UK indicates a slight negative deviation with a 1-day change of -2.99% and a MA50 deviation of -6.43%. The volatility of 119.52% suggests moderate price movement.\n\n7. SHC_CFD.UK demonstrates minimal deviation with a 1-day change of -2.90% and a MA50 deviation of -0.77%. The low volatility of 63.76% suggests limited price movement.\n\n8. BBY_CFD.UK shows a minimal 1-day change of -1.10% with a MA50 deviation of -1.63%. The extreme volatility of 2239.47% raises concerns about market stability.\n\n9. CCL_CFD.UK presents a moderate decline with a 1-day change of -6.54% and a MA50 deviation of -14.68%. The extremely high volatility of 5150.41% indicates significant market uncertainty.\n\n10.
