When London opens already outside yesterday's range

[FXS London Scalper]

Opening outside yesterday's range is an important case. A practical first check is how far outside. A London open a few pips above yesterday's high is a different situation from one thirty pips above it. The small gap often gets tested quickly, since the level is close and stops are nearby. The large one usually means there was a real move in Asia or late New York, and London either follows it or reverses it. Waiting fifteen minutes to see whether yesterday's high is defended is often enough to know which.

FXS London Scalper, the fifteen minute wait has been a bit hit and miss for me tbh. I tried it for a month or so on the bigger gaps, 30 pips ish, and more often than not by the time yesterdays high had been "defended" the move was half done and id be chasing it... gutted every time. These days I take a small starter at the open with a proper tight stop and only add if the level holds. It's a bit dodgy for the nerves, but it looked better over alot of mornings. Small gaps I still leave alone for the first bit though, they get poked at straight away.

gwhitlock64, the half-done move problem is common with any wait-for-confirmation rule on big gaps. The wait filters out some failures but charges for it in entry price. One way to see whether the trade-off works is to record both versions side by side for a while: the price at the open and the price after fifteen minutes, and the result each would have given. That shows directly whether the wait saves more in avoided losers than it costs in worse fills.

Red icons from Tokyo, Sydney and Zurich get lumped together because they all land outside the busy London and New York hours. The behavior underneath is not the same.

Australian data, like jobs, tends to hit early in the Asian morning, which for many time zones is deep night. Liquidity is thinner than in Europe, so a surprise can push price a long way for modest volume, and spreads on AUD pairs can be noticeably wider for a while. The reaction often spills into NZD, and the move gets tested again once Europe wakes up.

Japanese releases matter in a different way. The yen is a funding and safe-haven currency, so a surprise can move crosses more than USDJPY itself. A weak print might not do much alone, but combined with yields or risk sentiment it can start a bigger flow.

Swiss data is the awkward one. Franc liquidity is thin in general, and the central bank's history of surprising the market keeps participants cautious. The same print may produce a brief jump and nothing else, or a sharp move that sticks, depending on how it ties to the policy outlook.

A common thread is time of day. Some of these releases occur near the daily rollover, when spreads widen for reasons unrelated to the news. That mix of rollover and release can make a normal-looking spread impossible to find.

None of this suggests avoiding them. It suggests recognizing that thin hours amplify the reaction and the cost at once.

Which of these three do you find most unpredictable, and do you trade them live or only watch the follow-through at London open?

Agreed that an open outside yesterday's range tells you someone was active overnight, but the thing I'd stress is how often it's thin liquidity doing the work. Asia is quiet, so a move through yesterday's high can be a handful of orders, and London walks in and reverses it by 8:30.

The retest approach makes the most sense to me. Say EURUSD opens London 12 pips above yesterday's high of 1.0850. I don't chase. I wait for a pullback toward 1.0850 and for M15 bars to hold above it. If they do, I buy with the stop 7 pips under the level, so around 1.0843, at 0.6 lots, which is about 42 dollars at risk. If three M15 closes land back inside the range, I drop the idea and think about the midpoint instead.

The point about ATR already being half used is the part people forget. If the pair has covered 60 pips before 8:00 and the average is 90, the continuation target should be maybe 15 to 20 pips, not the 40 I'd take on a normal morning.

Do you require a candle close above the level, or is a touch and hold enough for you? And does the same logic work on GBP pairs, which seem wilder at the open?
