NT8 Simulated stop orders (Costly bug) (IMPORTANT)

General Discussions
1

I am notifying you all of a material defect in NinjaTrader’s simulated stop-loss order handling that appears to misinterpret price scale, rendering the platform unreliable for strategy execution and testing. (Many people have reported this in the original forum)

Summary of Defect

  • Observed behavior: When a simulated stop-loss order is placed at 6695.00, the platform converts the price to 669500.00, effectively shifting the decimal two places and nullifying trade logic.
  • Expected behavior: The order should retain the entered price of 6695.00.
  • Impact: This behavior corrupts strategy calculations and risk controls, creates erroneous order parameters, and undermines the integrity of backtests, real-time simulations, and any automation dependent on simulated stops.

Evidence

  • Attached screenshot reflects the incorrect conversion from 6695.00 to 669500.00.

This results in the stop loss not being respected and people losing a lot of money. This issue has been present on the platfrom since I started using NT8 in 2022 and I have brought it up many times.

It is a liability. Please fix it.

Have you notified NinjaTrader directly?

Notification here doesn’t do anything.

Yes, I sent it to them via email, but this is such a dangerous issue, that I thought I’d notify the community.
