PatternX Classic: deterministic pattern trading

What deterministic means here

PatternX Classic is the default mode on every account and the engine behind every pattern signal PatternX produces. It is deterministic: the same candles, market data and settings give the same result every time. Nothing in it is random, its rules and weights don't change on their own, and no language model takes part in a decision. Each step is a fixed rule or a fixed formula, so each step can be written down and checked. For the general idea, see deterministic trading.

The Classic pipeline

1. Detection. 20 rule-based detectors look for a pattern breaking out on the latest bar (how pattern recognition works).
2. Market filters. The breakout must pass shared checks on volume, volatility, liquidity, spread and order-book balance.
3. Scoring. The PatternX Score rates the setup from 0 to 100 with 13 weighted factors.
4. Your settings. Your minimum confidence (default 65, adjustable from 50 to 95), your enabled patterns and your risk settings decide whether it continues.
5. Risk engine. Trade, loss, exposure and sizing limits are checked before any order (risk controls).
6. Execution. You approve the signal, or auto mode sends it (automation).

The 13 factors

The score becomes the signal's confidence and places it in a band: Elite at 80 or above, High at 65 or above, Medium at 50 or above, Weak below 50. The engine never passes anything under 50. Two details are easy to miss. Pattern geometry and the reliability prior together carry only 24% of the weight, so most of the score is market context. And the score is a gate, not a ranking: PatternX doesn't sort signals by it. The PatternX Score methodology goes deeper.

For example, take two setups with identical geometry. One breaks out on a full-bodied candle, on about twice its average volume, in a liquid market with a tight spread. The other breaks out on a small-bodied candle, on volume just past the 1.2× minimum, with a wide spread. Both clear the filters, but breakout strength, volume, liquidity and spread together carry 0.35 of the weight, so the first scores clearly higher and has a much better chance of clearing a minimum of 65.

Transparency and reproducibility

Because the factors and weights are published, you can see why a signal scored as it did and which inputs held it back. Two honest caveats apply:

• One input moves over time. The historical win-rate factor switches from neutral to PatternX's live results once a market has 10 closed trades, and it keeps updating, so a similar setup can score differently a month later.
• Backtests are close, not identical. The backtester replays the same detectors but uses neutral market context and has no higher-timeframe or historical input, so its scores won't match live scores exactly.

Keep in mind too that the reliability prior is a fixed per-pattern value, not a measured statistic.

Classic or PatternX AI

Classic is one of two modes, set per account. PatternX AI, on Pro and Elite, adds an 8-factor context check after Classic has accepted a setup; detection is the same in both. Classic suits traders who want every decision traceable to a rule and a number. The Classic vs AI comparison covers the differences in detail.

Limitations

Deterministic is not the same as right. Fixed rules can be consistently wrong in markets they don't suit, and the score measures conditions, not outcomes. Classic doesn't re-check a pattern after the trade opens; the pattern's stop simply becomes the trade's stop. Targets are capped by your take-profit setting, so the full measured move isn't always used. And the "probability" figure shown with a signal is a heuristic, not a measured chance of winning.
