## Locked Methodology Invariants (Zero Parameter Bloat)[​](#locked-methodology-invariants-zero-parameter-bloat "Direct link to Locked Methodology Invariants (Zero Parameter Bloat)")

To prevent curve-fitting, the following methodology parameters are locked as immutable constants inside the EA:

* `InpUseFreeTrade = true`: Always banks 50% partial position at $+1.0R$.
* `InpMoveToBEAt1R = false`: Never moves Stop Loss to premature break-even.
* `InpTakeProfitR = 0.0`: No artificial Take Profit ceiling; rides full macro trend.
* `InpFilterMaxATR = true`: Setup rejected if entry-to-SL distance exceeds 2.5x ATR.
* `InpPendingExpiryBars = 3`: 3-bar pending order expiration.
* `InpMidlinePeriod = 20`, `InpContainmentMult = 2.25`, `InpCentreMult = 1.0`.
