summary: the screener has its own session selector that anchors every calculation in the table. choosing the right session isn't a preference — it's a data input that directly affects every report's output.
the screener's session selector is separate from the one on the reports page. changing the session in the screener doesn't affect your reports, and changing it in reports doesn't affect the screener.
the session you select is your anchor for all the live calculations running in the screener. every report column recalculates based on the session window you've chosen — so getting this right matters more than most people realize.
your session selection persists automatically — it's remembered the next time you open the screener.
available sessions
session | window (local time) |
New York | 9:30 AM – 4:00 PM New York time |
London | 8:00 AM – 4:00 PM UK time |
Asian | 8:00 AM – 5:00 PM Tokyo time (overnight in ET) |
getting this wrong is one of the most common reasons the screener shows unexpected results — the wrong session means the wrong IB window, the wrong gap reference close, and the wrong ORB window.
how the session affects your screener data
the session anchors the calculations for every report running in the screener:
gap fill — the prior session close (PSC) used as the fill target changes based on session
initial balance — the IB window shifts to match the selected session's open
opening range breakout — the range window shifts to match the session open
all other reports use the session window to define their reference periods
this is why the screener can look completely different when you switch sessions — it's not a display bug. the setups are genuinely different because the reference windows have shifted.
stocks: NY session only
if you switch to the Stocks tab, the London and Asian sessions are greyed out — only New York is available. stocks trade during regular trading hours (9:30 AM – 4:00 PM ET), so there's no London or Asian session data to work with.
on futures you get NY, London, Asia, and your custom sessions. when your asset is set to all, the session picker is locked, so switch to futures to change the session. Daily isn't offered on the screener; it's a reports and discovery session.
custom sessions on the screener (futures)
the screener now supports custom sessions for futures. any custom session you've built shows up in the screener's session selector alongside NY, London, and Asian when you're viewing futures — the same custom sessions you use on reports and what's in play. build or edit them the way you always have — open the session dropdown and choose + create custom session — and once saved they're available in the screener too.
this is futures only — the Stocks tab stays New York only, so custom sessions don't apply there (stocks trade a single regular-hours window). for the full walkthrough on building, editing, and deleting custom sessions, see sessions overview.
sessions and templates
your session selection is saved when you create a screener template. if you trade both NY and London, you can save separate templates for each — one with NY selected and your US instruments prioritized, another with London selected and your European-hours instruments at the top. switching between them takes one click.
common questions
why does the screener look completely different when I change sessions?
because the session is the anchor for every calculation. switching from NY to London shifts the IB window, the gap reference close, and every other time-based reference. the setups are genuinely different, not a display bug.
can I run two sessions at the same time?
no — one session is active at a time. if you trade both NY and London, run London in the early morning, then switch to NY when the US market opens. if you save templates for each, switching takes one click.
