D07-F06-A12 · LEVEL 2 GUIDED LAB · SYNTHETIC DATA
Volatility Stop
Where is a causal, ATR-scaled trailing boundary under the selected state machine? Walk the evidence clock one stage at a time. This lab teaches the publication contract; it does not simulate returns, platform parity, or trade performance.
Selected expression
long_stop_t=max(previous_stop, highest_close_n-k*ATR_n) until a reversal reset; short is symmetric
Availability rule
An output at t may use only finite, basis-consistent observations available through t; chart alignment never moves the information clock backward.
