FME_CFD.DE offers the best score with a clean setup near support, while AMCX_CFD.US presents a deep short-term dislocation with strong bounce potential. Remaining holdings are either working (ICG, STJ, OKTA showing positive PnL) or still within acceptable reversion timeframes. Portfolio stays within max 10 active positions and gross leverage limits. Avoiding overtrading by holding 11 existing positions unchanged."
