Carry math: 100,000 AUD, yen pips, $6.70
1.00 lot is 100,000 AUD. Yen conversion puts the 0.01 pip near $6.70, identical family to USDJPY, not to AUDUSD. Spread 0.5 to 1.2 pips. ATR 75 to 125 pips sits between Aussie dollar and the wilder GBPJPY. Handles 98.50, 99.00, 100.00 are intervention-and-carry conversation levels.
If you leave pip value at $10, 4.95 lots look "too small" versus AUDUSD 5.00, so traders bump size and then discover each pip was only $6.70 while the stop needed 30 pips of yen noise, not 20 pips of dollar noise.
Sydney-Tokyo overlap is the product
00:00 to 05:00 UTC is when this pair earns its keep: European books are thin, but Aussie and yen are both awake. US equity open 13:30 to 16:00 UTC is the second engine because AUDJPY is a risk barometer. S&P and Nasdaq selloffs dump the cross even if RBA is unchanged.
RBA 03:30 UTC and BoJ headlines are stacked landmines in the same overnight window. connect your MT5 account to Venasri and do not hold 4.95 lots through both stamps on one candle.
4.95 lots at 30 pips, haircut if NAS100 is open
lots = 1000 / (stop pips × 6.70). At 30 pips: 4.98, stored as 4.95 lots at 1%. At 0.50% that is 2.47 lots. Scalp 12 to 20, intraday 25 to 42, swing 65 to 105. Put 6.70 in the Half-Kelly Lot Size Calculator & Equity Guard.
NAS100 or US500 already on the book is the same risk-on expression. Copper and gold filters apply too. One 2.47 lot AUDJPY ticket plus a full Nasdaq ticket is how "Asia scalp" becomes a US-session daily-limit hit.
Trade 00:30 to 04:00 UTC, respect 100.00, skip dual CB
Best: Asian breakouts and EMA pullbacks while Europe sleeps, 00/50 yen handles, spread under 1.2, 30-pip-class stop. Cut size at 100.00 when officials are talking. NY equity hours only if you want beta, at reduced lots.
Confirm Asia clock, RBA/BoJ clear, and equity correlation on the Pre-Trade AI Confluence Checklist. AUDJPY is the overnight trend pair. It is not a quiet AUDUSD clone.
