The 4 PM London Close

Markets go crazy around 4 PM GMT. It's collectively known as 'The Fix.'

It's the 11 minutes of pure adrenaline when the big institutional desks are squaring their positions for the day. Trillions of dollars are moving through the pipes all at once.

Here's the thing — if you're a retail user trying to do a big conversion during this window, you're going to get caught in the spray. The spreads widen, the volatility spikes, and you might get a significantly worse filled price than if you just waited 20 minutes.

So the problem is timing. Most people just click 'convert' whenever they have the tab open.

Don't do that.

Wait — this matters. If you're moving enough for a house deposit or a business invoice, that 0.5% slip during the 4 PM close could cost you hundreds.

Actually, scratch that. It could cost you thousands if the market is particularly thin that day.

The smartest move is to wait until the dust settles. Let the big boys fight it out. Check back at 4:30 PM. The rates usually stabilize, the spreads tighten, and you can make your move in peace. Patience isn't just a virtue; it's a profit center.
