How to Validate TradingView Backtest Results Before You Trust Them
A practical validation checklist to separate robust strategy behavior from good-looking accidents.
Reproducibility is step zero
Re-run the same setup with fixed inputs. If the output drifts unexpectedly, investigate before any new optimization.
Trust starts with repeatability, not with screenshot quality.
Test neighboring windows
Shift the date window and observe degradation profile. Good systems bend. Fragile systems break.
One lucky window is not a strategy. It is a memory.
Audit trade concentration
Check whether results depend on a handful of outsized trades. Concentrated return profiles increase fragility risk.
If removing two trades destroys performance, you found a red flag, not alpha.
Actively search for failure modes
Validation is not proving your idea right. It is trying to prove it wrong and measuring what survives.
This mindset is less fun in the short term and much safer in the long term.
