The rollover window is not a normal market, so stop treating it like one

[Shadow Trader]

A scenario that plays out at 4:58pm New York time more often than anyone admits. EURUSD has been grinding sideways for forty minutes. The range is three pips wide, the chart looks tidy, and a setup that has worked all week appears. The spread reads 0.4, a touch wider than normal but nothing alarming. The order goes in.

By 5:01 the spread is 6 pips. By 5:03 it's 11. The position is a loser from the first tick, and a stop placed four pips away gets triggered by a bid that dips for a fraction of a second while the ask is stretched. Then the spread settles, price returns to where it started, and the trade would have been a winner if it had never been opened.

What happened is routine. Around 5pm New York, the large liquidity providers roll their books to the next value date. Quotes get pulled, refreshed and repriced. On a retail feed, the result is a spread that can jump from a tenth of a pip to ten or fifteen on pairs that normally behave.

The part people miss is how calm it looks. The price barely moves during this stretch, so the chart reads as quiet and easy. It isn't quiet. It's empty. A tight-looking range with a spread ten times normal is a trap for anyone running a three pip target.

Brokers handle it differently. Some widen early, some late, and some stagger it by instrument, so EURUSD might go first and AUDNZD ten minutes after. Only a log can say when the broker's own window starts and stops. A spread recorded every second for two weeks and plotted by clock time shows it plainly, and the result is usually a surprise to anyone who assumed the window was five minutes long.

Plenty of scalpers simply close the platform for that stretch. Nothing of value is lost, and a lot of small damage is avoided.

Has anyone mapped the exact minute their broker starts widening, and does it match the minute it stops?
