How news weeks change my broker cost rankings

[LondonScalper]

Broker cost rankings are not static -- news weeks scramble them.

In quiet mid-week London, one venue can look cheapest on my majors. In a CPI or NFP week, the ranking that matters is fill quality under stress, not the marketing spread screenshot from Tuesday.

What I re-rank on event weeks

• Rejects in the +/-5 minutes around tier-1 prints
• Slippage distribution (not just the average)
• Whether I could flatten on the phone/app if the desktop platform hiccupped
• Symbol behaviour on XAU vs EUR -- they do not always degrade together

I keep a separate tab: "stress week" vs "normal week." Mixing them made me defend a broker that was fine for grind sessions and expensive when it mattered.

I am not hunting perfection. I am deciding whether my usual ticket type (market vs limit) and size still make sense when the calendar is red.

How do you adjust cost comparisons when the week is packed with data -- different size, different venue, or simply fewer trades?

News weeks reorder broker rankings

Quiet weeks hide sins. CPI and FOMC weeks expose them: slippage tails, rejects, widened spreads exactly when you wanted precision — or exactly when you should have been flat.

I keep two ranking lenses on purpose:

• Baseline costs in normal European mornings.
• Event-week costs at the blackout borders and in the first minutes after a release if you trade them at all — I usually do not.

A broker that looks cheap on a quiet Tuesday can be expensive on a red-folder Wednesday. My scorecard weights event tails even if I am flat through the print, because pending-order behaviour and reopen quality still matter when the desk comes back. Rankings without a news-week column are incomplete for scalpers.

I also freeze broker changes during heavy event weeks unless there is an outage. Switching books into CPI or FOMC adds a second experiment on top of the calendar. One variable at a time is enough for a full-time desk.

Do you ban trading the release entirely, or trade the edges with a separate, harsher cost filter written before the week starts?
