Trading indicator performance is easy to market badly. A percentage without context can look impressive while telling you almost nothing about how the result was measured.
1. Check the timeframe
A result from a three-minute chart should not be mixed with a result from a five-minute or one-hour chart. Each timeframe is a separate sample.
2. Check the number of trades
Small samples can move dramatically after only a few trades. A low-sample result should never be presented as proven or stable.
3. Understand the win rule
Ask what counts as a win. Does an early target count? Does the system record the final outcome? Different rules can produce different-looking win rates.
4. Look beyond win rate
Total R, average R, target hit rates, losses and break-even outcomes can provide useful additional context. A high win rate is not automatically better if the payoff profile is poor.
5. Separate historical data from future expectations
Historical results describe a past sample. They are not a promise about the next trade or the next month.
How NGF presents performance
NGF aims to show timeframe, sample size, measurement period and the relevant outcome rule near displayed statistics. Gold uses a complete-outcome model, while S&P 500 and Nasdaq use their stated TP2 win rule.
