The period available during strategy creation is explicitly identified. Development performance is useful, but it is not independent evidence.
OOS data is deliberately excluded from development. Exact start and end dates are disclosed, and OOS statistics are reported separately.
After the validated parameter set is frozen, the strategy is observed chronologically in simulation. This is not presented as live trading.
When live evidence exists, it is shown separately. If it does not exist, the website will say so rather than imply otherwise.
Commission, slippage and execution assumptions are disclosed where relevant to the validation record.
A commercial release must demonstrate more than historical fit. It must survive independent evidence and continue to be monitored after release.
