Roundup: Surviving the London open, the rules scalpers actually keep for the first 90 minutes
The London open has a lot of thin threads on this board: playbooks, focus rules, fade rules, three-strike rules, and a quarterly review of which major gave the cleanest opens. They cover the same 90 minutes from different angles, so here's what they add up to.
Stricter rules for the open than the rest of the day
The first 30 minutes playbook thread is clear that the open is both where the edge is supposed to be and where the most damage happens. So the open gets its own rules: a tighter spread filter than later in the day, only pre-marked levels with no improvising mid-spike, one open risk at a time, and the news blackout overriding everything.
The first 15 minutes thread adds what to expect: spreads come in from Asian levels, though brief bursts of wide quotes still show up, and false breaks of the Asian range happen often. It also has a small practical tip: have your size calculator show risk in money and the stop in pips alongside the lot size before you send. With all three in view, most fat-finger mistakes get caught, which are more likely in a fast open.
One idea, written down
The single-idea focus thread describes the old open as a buffet: fade Asia, chase the break, scalp the pullback, then a chaotic journal. The rule now is one A-idea in the first 60 to 90 minutes, written before the open in one sentence with level, trigger and invalidation. Flat is a valid result if it doesn't trigger.
The first M15 candle thread on GBPUSD is a simple framework that fits this: mark the high and low of the first M15 candle after the open as early boundaries, and only act when an M5 candle closes outside one of them. A reply notes it gets less useful when that first candle is huge, roughly more than a third of the pair's average daily range, because the lines are too far apart to be boundaries.
Fakeouts
Two threads deal with failed moves. The EURUSD failed drive thread only fades a sharp drive that tags a known level or Asia extreme, loses momentum and reclaims inside the opening structure, never one still making fresh extremes with acceptance. A reply makes a timing point: 07:00 to 08:00 London is before the cash open, so the drive is built on thinner liquidity than it looks.
The gold fakeout thread lets the first spike happen without you, marks the extreme, and only takes the reversal if price reclaims the pre-spike level and holds. A reply gives it ten to fifteen minutes and flags 10:30 London, the LBMA morning auction, as another time to watch on gold.
Knowing when the open is over
The three-strike thread counts process breaches, not losses: chasing after a miss, a setup outside the pre-marked levels, overriding a blackout because it "looks clean". Strike one, note it and tighten up. By strike three, the open is done. A reply uses the same rule so a messy first hour can't become a messy day.
Which pair?
The quarterly review thread ranked four majors by how often the London range break ran at least 1.5 times the range with no more than one false break. It's one trader's measure over one quarter, but the method is worth copying. Your own clean-open stats per pair will tell you more than anyone's favourite.
