Demetra Session Split Overnight Gap Risk

Know what your stop cannot protect, before you hold overnight. Session Split separates what a symbol did inside the session from what it did overnight, measures how often the night jumped past a stop, and gives a hold-or-flat reading for the coming night. It never trades on live charts.

Main features

• Overnight vs in-session: total move and how often each part was up, over the trading days you choose.
• Night risk: how much of the day-to-day movement happens outside the session.
• Stop Leak: how often the night jump was larger than the share of the normal session range you choose, a jump a stop cannot fill.
• Worst night in the sample, with its date.
• Next night by weekday: the coming night's own history (Friday night is into Monday; symbols that trade at the weekend, for example crypto, keep their weekend nights).
• A reading for the coming night: hold-friendly, hold with a smaller size, or flat before the close. This is a summary of past statistics, not a signal.
• Session hours chosen automatically by market type (forex, metals, indices, energy, crypto, stocks) and placed on your broker's server clock, or set by hand. They follow the server clock while it runs, also at the daylight-saving change, without a restart.
• History counted in trading days: the short weekend bars of forex and indices are not counted. If the broker has too little history, the panel says how many session days it found and how many it needs.
• Countdown to today's session open or close, on the server clock.
• Optional alert before the session close: popup, sound, push, e-mail. Sent only while connected and close to the planned time, so a restart never fires a late alert. Never in the Strategy Tester.
• Symbol switcher in the panel through your Market Watch. A symbol the Lab had to add to Market Watch is hidden again when you leave it.
• Panel with an explanation on every row. Minimize hides the panel and the lines. On a chart too small for the full panel, it folds itself to a title bar. No account data on screen.
• Out-of-range inputs are refused with one clear message. No DLL, no web requests. English UI. (The Strategy Tester demo opens one validator trade.)

Trading involves risk of loss. Session Split describes how sessions behaved in the past; it gives no trading signals, and past behaviour does not guarantee future behaviour.
