ADX Trend Short

Overview

The ADX Trend Short strategy combines two components of the Directional Movement System: ADX (Average Directional Index) measures raw trend strength regardless of direction, while DMI− (Minus Directional Indicator) confirms the bearish direction. A SHORT entry fires only when both agree — strong trend and downside direction confirmed by a fresh cross.

Discovered 2026-05-04 via a 4,116-combination parameter sweep across 50 coins. The 12H timeframe with SL 15% / TP 5% produced an OOS/IS profit-factor ratio of 1.01 — meaning the strategy performed equally in unseen data as in its training window. This zero-decay characteristic earned it verified status.

How It Works

1. ADX filter — ADX(14) must be above 25, confirming the market is in a trending (not ranging) regime
2. DMI cross — DMI− (selling pressure) crosses above DMI+ (buying pressure) on the current bar
3. Entry — SHORT on the next bar’s open after the cross is confirmed
4. Exit — TP 5% / SL 15% / 4-bar (2-day on 12H) timeout

Why It Works (Thesis)

ADX above 25 filters out choppy, low-volatility markets where crossover signals are noise. By requiring a concurrent DMI− cross, the strategy enters after directional commitment has been established — not on anticipation. The result: a high-WR setup (65.5%) where most entries are aligned with genuine trend momentum rather than mean-reverting noise.

The 12H timeframe eliminates intraday noise that plagues 4H and 6H signals, producing cleaner trend confirmation with more decisive follow-through. The wide SL (15%) accommodates the natural volatility at this timeframe while the tight TP (5%) locks in profits quickly — the market rarely gives back gains once a 12H trend is established.

Results (2-year backtest, IS/OOS split, measured 2026-05-04)

Metric	IS (May24–May25)	OOS (May25–May26)	Combined
Total trades	239	248	487
Win rate	~65%	~66%	65.5%
Profit factor	1.68	1.70	1.68
Coins profitable	37/50	36/50	—

OOS/IS ratio: 1.01 — OOS profit factor (1.70) exceeded IS (1.68). This is the defining characteristic of this strategy: the edge does not decay in unseen data.

Multi-window (4 rolling 6-month periods, 6H scan): W1=2.02 · W2=1.69 · W3=1.28 · W4=1.27 — profitable in all 4 windows. The 12H variant was selected as optimal from this scan.

Caveats

• 12H signals fire roughly once per coin every 2–3 days — lower frequency than shorter timeframes.
• Wide SL (15%) means individual losses can be substantial; manage position size accordingly.
• 487 total trades across 50 coins over 2 years — thin per-coin sample; diversification across coins is important.
• Not live-tracked on OKX. Backtest only.
