Market Hours
The sessions when a venue is open and when liquidity typically concentrates.
Hours define which playbook you are actually running. Overlap sessions, cash opens, and maintenance breaks change spreads and the mix of participants. A method sampled at one hour can fail at another without the rules being ‘wrong’ — they were applied to a different product.
