Warm-up trade size for the first 30 minutes after a holiday gap

[LondonScalper]

Post-holiday / long-weekend process — sizing, not prediction.

First London after a holiday gap, my book is often messy: wider spreads, odd gaps on crosses, and my own rhythm is off. Full size into that window has never been an edge for me.

Warm-up protocol
• First 30 minutes after my session open: half size or less, even on A+ levels
• Prefer known majors over thin crosses
• One open risk at a time
• Explicit permission to take zero trades if spreads fail the filter

The warm-up is not a mandatory trade. It’s a cap. If nothing is there, I sit. If something is there, I still don’t earn the right to full size until the tape looks normal and I’ve executed at least one clean ticket without process drama — or the 30 minutes elapsed with spreads in line.

What I’m protecting
Not just money — decision quality. Holiday returns are when “I need to make up the days off” shows up. The size cap removes that lever.

I write “WARM-UP” on the sticky next to the date so it’s visible. After the window, I either confirm normal size or keep the throttle if conditions stay weird.

Do you use time-based warm-ups, or only spread-based go/no-go after gaps?

Hi LondonScalper,

I use a hybrid of both, but the spread filter acts as the hard gatekeeper while the time limit serves as the probation period.

If I boot up the terminal after a UK/US bank holiday and the top-of-book spreads on the majors are still printing wider than their normal average, the time limit is irrelevant. The session is untradable. I don't need to wait 30 minutes to realize that liquidity providers are still sidelined and quoting wider to protect themselves from price uncertainty; the gap between the bid and ask immediately tells me the institutional book is thin.

However, even if spreads look tight at the open, I still enforce a time-based probation—usually the first 45 minutes of London. That is the execution warm-up. Tight top-of-book pricing might remain intact, but market depth often weakens significantly during these periods. You can see a normal spread on Cable, but if you hit the market and suffer slippage because the order book is a ghost town, you just paid the hidden holiday tax.

The time buffer protects against that invisible thinness. By forcing half-size or a complete stand-aside for the first 45 minutes, I get to watch the morning's first liquidity sweep unfold without my full capital exposed to it. It neutralizes the exact psychological trap you mentioned: the urge to "get back to work" and force a mediocre ticket just because the chart is moving again.

I use a mechanical barrier similar to your sticky note. I disable one-click trading on my execution platform during that first hour. If I want to enter a position, the confirmation ticket pops up, forcing me to manually type the lot size and consciously verify if the setup is genuinely A+ or just post-holiday boredom.

When you take that half-size warm-up trade, do you tighten your stop-loss distance to compensate for the erratic tape, or do you keep your standard structural invalidation and absorb the wider risk on the smaller lot? Are you applying this 30-minute rule strictly to the post-holiday return, or do you also enforce it on the Friday sessions leading into those long weekends?

Spread as hard gate plus a time probation is the right hybrid. Tight top-of-book after a holiday still lies about depth.

On my desk the warm-up is strict: first 30–45 minutes post-holiday are half-size or flat, and one-click stays off until I’ve seen one clean liquidity sweep without needing to chase. I keep the structural invalidation distance unchanged — I don’t tighten stops into erratic tape — and absorb the wider risk only via smaller size. Tightening the stop after a gap is how you get wicked out of a valid level.

I apply the same probation on the Friday into a long weekend, not only the return day. Holiday tax works both sides of the calendar.

To your question: standard invalidation, smaller lot — never a tighter stop as compensation. Do you ever shorten the 45-minute window if depth and spreads both look normal by minute twenty, or is the timer absolute?

Holiday gap: half size for thirty minutes

First session after a long weekend, my rhythm and the book are both messy. Full size into that window has never been an edge. Warm-up protocol from Frankfurt: first thirty minutes at half risk, only A-setups I already trust, no new experimental plays.

Wider spreads and odd cross gaps are normal. I also widen my “stand aside” sensitivity — if costs look wrong, I wait. The goal is to re-sync execution and attention, not to “make back” the days the market was closed.

Prop accounts get the same warm-up. Trailing DD does not care that you feel rusty.

After the thirty minutes, size returns only if spreads and my own click discipline look normal — not because the clock finished.

I also avoid new symbols in the warm-up window. Familiar pairs only. Holiday gaps are not the time to discover how a cross fills on my broker.

Do you use a fixed half-size window, or do you judge readiness by a checklist (spread, two clean scratches, calm tags)?

Post-holiday / long-weekend process — sizing, not prediction. First London after a holiday gap, my book is often messy: wider spreads, odd gaps on crosses, and my own rhythm is off.

On your two questions, from my side.

I keep the structural stop and cut the size. Tightening the stop to make a warm-up trade fit is the wrong adjustment in a thin book, because the erratic tape you describe is precisely what hits a tight stop. If the normal invalidation at half size is still more risk than I want, the answer is no trade rather than a nearer stop.

And yes, the Friday before a long weekend gets its own treatment, though a different one: an earlier flat time rather than a warm-up. Liquidity drains from mid-afternoon London, and nobody wants to hold a position into three days of headlines.

The distinction I'd add is which country is on holiday. A US holiday with London open gives you a normal-looking morning and a very thin afternoon, since the usual US flow never arrives. A UK bank holiday is the reverse: GBP pairs are sluggish in the morning while EUR crosses trade more or less normally. So I check which centres are closed rather than labelling it simply a holiday day.

Disabling one-click trading for the first hour is a good trick. Same principle as the sticky note, just enforced by the platform instead of willpower.
