Looking for Add‑On to Lock Contract Size (No Edits or Overrides Possible)

Trade API - General
1

Hi everyone,

I’m looking for a NinjaTrader 8 add‑on or method that enforces a fixed contract size that cannot be changed during the trading day — for example, exactly 2 contracts only.

The goal is absolute enforcement:

  • The contract size should be permanently locked once the day starts.
  • I should not be able to manually edit or override it from the Chart Trader, Order Entry, ATM, or account settings.
  • Ideally, the restriction stays in place until end‑of‑day reset (e.g., session close or rollover).

I’ve tested RiskMaster and some other risk management scripts, but they can still be modified if you adjust parameters or reopen the settings panel. I’m looking for something even stricter — a “no‑override, no‑permission” rule to enforce daily discipline.

If anyone knows of a third‑party solution?
