Introduction
In the structured and empirically grounded world of No-Nonsense Forex (NNFX), every component of a trading system must earn its place through rigorous backtesting and statistical validation. The Grucha Percentage Index, an innovative oscillator designed to capture nuanced price action shifts, has been tested here as a Confirmation 1 (C1) indicator within the NNFX ecosystem.
This evaluation integrates the Grucha Percentage Index with the default Baseline (20-period SMA), the default Volume indicator (ADX 14 with threshold 25), and the standard Exit (Heiken Ashi candles). The objective was clear: to assess whether Grucha can effectively enhance signal quality and decision-making across varying market conditions.
We conducted backtests on 8 major Forex pairs over two timeframes: a 1-year snapshot (for pre optimization) and a robust 5-year span (for long-term viability). The results offer insight into how this indicator behaves in both trending and choppy markets and whether it can reliably serve as a first-line Confirmation in the NNFX architecture.

Interpretation Based on NNFX Standards
Profit Factor (4.92)
The Grucha Percentage Index meets the NNFX minimum threshold of 1.30, signaling fantastic profitability over the long term. This makes it a contender for live usage or further building an algorithm around it as a C1.
Winning Rate (54.68%) and Payoff Ratio (1.45)
While the win rate slightly exceeds 50%, the payoff ratio is modest. This pairing suggests consistency rather than explosiveness. The system favors frequent but smaller gains, aligning with NNFX principles when risk controls are in place.
Trade Expectancy ($29.47)
A positive expectancy per trade, is a solid signal of structural potential. However, it hints that further optimization (especially in C2 or exit conditions) could unlock even stronger performance.
Drawdown (3.97%)
The system stays well below the 10% threshold accepted in prop firm evaluations. This level of drawdown reflects sound risk management and well-behaved equity curve behavior.
Loss Sequences (Avg 2.88 | Max 4,13)
Streaks of consecutive losses are controlled and do not show major instability. This implies the indicator does not overreact in sideways markets, though refinement in signal reliability could improve.
These indicators together define the overall health of the system and its readiness for live use.
Overall Diagnostic
| Category | Evaluation | Comment |
| Profitability | Strong | PF well over 4,92, long-term positive |
| Risk Management | Strong | Low drawdown, solid recovery profile |
| Robustness | Moderate | Relatively consistent but needs a C2 |
| Signal Reliability | Moderate | Decent win rate |
| Optimization Potential | High | Parameters and C2 combo could improve edge |
NNFX Recommendations
- Refine confirmation entry logic — to improve payoff ratio without losing win rate.
- Pair with high-quality C2 — to boost signal selectivity and trade quality.
- Monitor per-pair behavior — focus on pairs that exceed PF > 1.5.
- Compare vs Naked Baseline — to confirm added value from Grucha Percentage Index.
- Explore Grucha as a C2 — the indicator’s consistency may work better as secondary confirmation.
Final Assessment
The Grucha Percentage Index displays real potential as a C1 indicator under the NNFX framework. While not explosive in profit generation, its amazing PF (4.92), solid win rate, and disciplined drawdown suggest it can be part of a robust system, especially if paired with a strong C2 and smart exit mechanics.
Some pairs underperform, but the system is far from erratic — this is a candidate for further refinement rather than outright replacement. The indicator shows consistent behavior, which is often more valuable than headline-grabbing returns.
