I will fix and debug your ninjatrader ninjascript code nt8 or nt9


Level 1
About this gig
Fix, debug, and migrate your NinjaTrader NinjaScript code NT8 and NT9
If your NinjaTrader strategy or indicator was working fine on NT8 and started throwing errors, crashing, or missing fills after moving to NT9 that's what I fix. I debug NinjaScript strategies, indicators, and custom addons: sync/order errors, false signals, crashes, memory leaks, and NT8NT9 API mismatches.
What I handle:
- NinjaScript bug fixes and root-cause debugging (crashes, leaks, false signals)
- NT8 to NT9 migration porting your existing logic over without changing your strategy's behavior
- Compatibility audits before you upgrade, so you know what will break ahead of time
- Custom NinjaTrader addons and indicators built from scratch (C#/NinjaScript)
How it works: send me your error logs, the instrument/pairs you trade, and your .cs files (or a description of the addon you want built). I'll reply with a scope and time estimate before any order starts, so there are no surprises mid-project.
All code is written by me, fully commented, and delivered with a written explanation of what was wrong and what changed. This is a coding/debugging service.

FAQ
Do you need my source code or just the compiled file?
I need the .cs source files — compiled-only files can't be debugged.
Can you guarantee my strategy will be profitable after the fix?
No, I fix bugs and migrate code; trading results depend on your strategy and market conditions, not the code alone.
What if the bug turns out to be bigger than expected?
I'll tell you before starting extra work, no surprise scope creep.
