  "title": "Does the London Open Range Break Hold? 93,843 Breaks Measured",
  "description": "The London opening range breakout is one of the most traded retail setups and one of the least measured. Across 93,843 breaks on 26 instruments and 16 years, a break extended a further one range height before failing 50.3% of the time. That is a coin flip before costs, and a loss after them.",
