| Market Hours Strategy | ASX pre-open runs 7:00-10:00 AM AEST. Calculate ADX on previous close, review the overnight SPI 200 night session and the US close (the ASX often gaps to follow Wall Street) to identify which instruments are trending • 10:00-11:00 AM AEST - the ASX equity market opens via a staggered single-price auction; wait for ADX confirmation and avoid acting in the first 10-15 minutes while the open settles • 11:00 AM-2:30 PM AEST - lower-news window and the optimal period for ADX-based trend entries on SPI 200 and ASX share CFDs • 2:30-4:00 PM AEST - on RBA decision days the cash rate lands at 2:30 PM; book intraday profits and reassess daily ADX. The ASX closing single-price auction is at 4:10 PM |
| Asx Specific | The S&P/ASX 200 (XJO) gives clean ADX signals due to high liquidity, but it is more range-bound than the US indices because it is dominated by rate-sensitive banks and dividend payers and lacks a large growth/tech component; sustained trends are less frequent, so consider a 22-25 entry threshold and more patience • Global index CFDs (US 500, Wall St 30) often trend more cleanly than the ASX 200 and set the overnight lead for it; ADX > 25 is reliable. Remember leverage on a major-index CFD is capped at 20:1 (5% margin) for retail clients in Australia • Resources leaders (BHP, RIO, FMG) are the most trend-prone Australian names because they track iron ore and China demand; Financials (CBA, WBC, NAB, ANZ) are rate-sensitive. Stick to liquid ASX 50 names where ADX is cleaner; mid/small caps can show erratic ADX • SPI 200 futures are valued at A$25 per index point (about A$212,500 at 8,500 points), tick size 1 index point = A$25. Share CFDs are 1 CFD per underlying share; index/commodity CFDs are sized per point/contract and vary by broker • SPI 200 futures use exchange margin set by ASX Clear. Retail CFD leverage is capped by ASIC: major indices and gold 20:1 (5%), other commodities and minor indices 10:1 (10%), shares 5:1 (20%), major FX pairs 30:1 (3.33%) |
| Commodity Cfds | ADX is highly effective on WTI/Brent crude CFDs due to strong trends; most active during the London and US sessions (Australian evening to early morning). Retail leverage on crude is capped at 10:1 • Gold (XAU/USD) shows prolonged trends; ADX > 30 often signals multi-day moves. Gold is treated as a 'major' for margin and gets the more favourable 20:1 retail cap • Volatile with quick ADX spikes; use a shorter period (10). Like crude, non-gold commodities are capped at 10:1, so size carefully • Commodity CFDs trade nearly 24 hours, 5 days a week; the strongest trends usually form during the London/US overlap, which is the Australian evening and overnight |
| Forex Trading | AUD/USD is the key major and a classic 'risk-on' commodity currency; ADX is effective for capturing macro trends. Drivers are the Fed-RBA rate differential, iron ore and commodity prices, China data, and global risk sentiment. A standard lot is 100,000 units; majors are capped at 30:1 (3.33% margin) • Monitor the US Dollar Index (DXY), which is inversely correlated with AUD/USD, and watch iron ore and broad commodity prices, which are positively correlated; confirm AUD/USD ADX trends against these • Unlike the RBI managing USDINR, the AUD floats freely and the RBA rarely intervenes in the currency. The real driver is RBA cash rate policy (eight meetings a year, decision at 2:30 PM Tuesday) and rate differentials; ADX can spike around RBA and US Fed decisions |
| Tax Implications | Australia has no securities transaction tax (no STT equivalent). Costs are brokerage and exchange fees plus, for CFDs, the dealing spread and overnight financing; GST is generally embedded in fees on financial supplies • The ATO distinguishes an investor (gains on capital account, eligible for the 50% CGT discount if held over 12 months) from a person carrying on a business of trading (profits taxed as ordinary income on revenue account, losses deductible, no CGT discount). Active futures and CFD trading is typically revenue account; CFDs in particular are treated on revenue account under ATO ruling TR 2005/15 • Rather than advance tax, the ATO collects tax on business/investment income through quarterly PAYG instalments once income exceeds the relevant entry thresholds • Whether you are a 'trader' versus an 'investor' is judged on volume, frequency, sophistication, capital and whether the activity is run in a business-like manner. A Tax File Number (TFN) is required and detailed records of every trade, cost and rationale should be kept |
| Offshore Lead And Flows | The ASX 200 frequently gaps to follow the prior US session (S&P 500); a strong, established US trend often precedes a rise in ASX 200 ADX the following morning • China activity data and the iron ore price drive the Resources sector; powerful moves in BHP/RIO/FMG can lift index-level ADX, while weak commodity prices keep the resources-heavy index ranging • Australia's roughly A$4 trillion superannuation system provides structural, largely passive buying; steady index inflows can dampen ADX and produce a mean-reverting grind rather than clean directional trends • Track the US close and the overnight SPI 200 night session, the ABS economic data calendar, and the RBA meeting schedule to prepare for the next session • SPI 200 futures expire quarterly on the third Thursday of March, June, September and December; ADX may spike around rollover and expiry |
ADX and RSI measure completely different things. ADX measures trend STRENGTH - how powerful a trend is, regardless of direction. RSI measures momentum and overbought/oversold conditions - whether price has moved too far too fast. ADX tells you IF you should use trend strategies (high ADX) or range strategies (low ADX). RSI tells you whether price might be due for a pullback. They serve different purposes and are best used together: use RSI for entries when ADX is low (ranging market), and use trend-following when ADX is high.
No, ADX is mathematically bounded between 0 and 100. However, in practice, ADX rarely exceeds 60-70 even in the strongest trends. Readings above 50 are quite rare and indicate exceptional trend strength. The most common operating range is 15-45 for liquid instruments like the ASX 200 and the US 500 CFD.
You're probably trading DI crossovers without filtering by ADX level. When ADX is below 20-25, the market isn't trending, and DI crossovers are just random fluctuations that reverse quickly. This happens often on the ASX 200, which spends long stretches range-bound. Solution: Only act on DI crossovers when ADX is above 25 AND rising. This single filter will eliminate most whipsaw losses.
The default 14-period works well for most situations on daily charts. For intraday trading on 15-minute or hourly charts, try 10-period for faster signals. For weekly charts or position trading, 14-18 periods work well. The principle is: shorter timeframe = shorter ADX period, longer timeframe = same or slightly longer ADX period.
ADX is a lagging indicator - it CONFIRMS trends after they've started, rather than predicting them before they begin. This is actually a feature, not a bug. ADX's job is to tell you when a real trend exists, preventing you from trading false breakouts. The lag means you miss the very first part of moves, but you avoid many false signals.
Start with the higher timeframe ADX to establish the trend context. If daily ADX is above 30 with +DI dominant, the market has a confirmed uptrend. Then use the lower timeframe (hourly) ADX for entry timing. Look for hourly DI crossovers in the direction of the daily trend when hourly ADX is above 20. This gives you higher timeframe trend confirmation with lower timeframe entry precision.
This is a warning sign. High ADX with converging DI lines suggests the trend is losing conviction even though it was recently strong. The market may be preparing for a reversal or consolidation. Tighten stops on existing positions and avoid new entries. Wait for DI lines to separate again before trading.
Use tighter stops when ADX is high (above 35) because the trend should move smoothly with less pullback. A 1.5x ATR stop often works well. When ADX is moderate (25-35), use wider stops (2x ATR) to accommodate normal pullbacks. When ADX is just above 20, use even wider stops (2.5x ATR) as the trend is less established. This scaling acknowledges different market behaviors at different trend strengths.
Absolutely. When ADX is above 30, consider buying options (calls in uptrend, puts in downtrend) as trends tend to persist. When ADX is below 20, the market is ranging - ideal for selling options (short straddles, iron condors) as prices oscillate rather than trend. ADX helps you choose between directional (high ADX) and non-directional (low ADX) options strategies. In Australia, ASX index options (XJO) and options on the top listed stocks are the usual venues.
ADX-price divergence occurs when price makes new highs/lows but ADX fails to make new highs. For example, the ASX 200 makes a new high but ADX shows a lower peak than its previous peak. This indicates the trend is losing strength despite price continuation. Use this for: (1) tightening stops on existing positions, (2) taking partial profits, or (3) preparing for potential reversal trades with tight stops.
Institutional traders use ADX for portfolio-level decisions, not just individual trades. They allocate more capital to high-ADX instruments and reduce exposure to low-ADX instruments. They also use ADX for regime identification - running different systematic strategies in trending vs ranging regimes. Additionally, institutions often combine ADX with order flow data, using ADX to confirm that institutional money flow is creating a sustainable trend.
Proper ADX backtesting requires: (1) Testing across multiple instruments to ensure robustness, (2) Testing across different market periods (trending years, ranging years), (3) Using walk-forward analysis (optimize on 3 years, test on 1 year, roll forward) to prevent overfitting, (4) Testing threshold variations (20, 22, 25, 28, 30) and period variations (10, 12, 14, 18). The goal is finding parameters that work reasonably well across all conditions, not perfectly in any single condition.
The complete Wilder system combines ATR (volatility measurement), Directional Movement (ADX, +DI, -DI for trend identification), and Parabolic SAR (trailing stop management). Using all three together provides a complete trading framework: ATR for position sizing and stop width, ADX/DI for entry signals, and SAR for exit management. This integrated approach outperforms using ADX alone because each component handles a specific aspect of trade management.
When multiple correlated instruments (like the ASX 200 and the US 500, or the big banks CBA/WBC/NAB/ANZ) all show high ADX in the same direction, your portfolio has concentrated exposure - and the ASX often simply follows the US lead. Solutions: (1) Reduce total position size across correlated instruments, (2) Choose only the highest-ADX instrument among correlated options, (3) Add less-correlated positions (commodity CFDs, FX) to diversify, (4) Use portfolio-level ADX monitoring to track total trend exposure.
ADX cannot predict regime changes in advance - it's a lagging indicator that confirms regimes. However, certain patterns provide early warnings: (1) Prolonged ADX compression below 15 often precedes breakouts, (2) ADX-price divergence warns of trend exhaustion, (3) ADX peaking above 50 and turning down signals regime transition from trending to consolidation. Experts combine these ADX patterns with other leading indicators (volume, market breadth, sentiment) for better regime change detection.
