summary: the initial balance (IB) report isn't locked to the standard 9:30–10:30 NY first hour. you can set a custom time window (like 10:20–10:30, or an afternoon 2:00–3:00 block) and run it on the Asian or London session — or on a session you build yourself. the single-break, double-break, breakout, and breakdown numbers all recompute for exactly the window you choose.

prefer to watch first? André builds an afternoon 2–3pm IB on NQ end to end — custom session, indicator setup, and how to read the stats — here:

yes — both are supported. the IB report has two things you can change:

so if you don't trade the classic first hour — say you build your balance off 10:20–10:30, or you trade an afternoon block, or the Asian session open — you can point the report at that exact window and get the break stats for it.

by default the IB report measures the first hour of the NY session (9:30–10:30 ET). to measure a different window instead:

the same customization also carries into edgeful AI, so if you analyze the IB report with a custom window set, the AI reads the data for that window too (see how to analyze reports with edgeful AI).

the session selector is separate from the time window. switch the report's session to Asian or London and the IB is measured against that session's hours instead of the NY open.

beyond the built-ins, you can also build your own session. in custom sessions, create a new session, give it a name, set its start time, end time, and timezone, then select it on the report. this is what lets you run an IB on a window none of the presets cover — like an afternoon block. the full walkthrough for creating, editing, and deleting sessions is in sessions overview.

this matters because an IB in the Asian session is a genuinely different measurement than an IB in NY — the reference open, the liquidity, and the typical break behavior all differ. pick the session that matches the market you actually trade, then set your custom window within it if you need one.

the classic IB is the first hour of the session open, but nothing stops you from measuring an IB later in the day. an afternoon block — say 2:00–3:00 PM ET — builds its own high and low, and price breaks or holds that range just like the morning one does. this is sometimes called a second, or afternoon, IB.

to set one up:

the session length matters here. the IB takes the first hour (2:00–3:00), which leaves the rest of the session (3:00–4:00) for a break to happen. a break only counts if it lands inside the session window — if price breaks the range after your session ends, the report doesn't count it. so set the session end to give the break enough room, but keep it tight enough that you're measuring the behavior you actually trade.

once you know the window you want, the edgeful IB TradingView indicator (edgeful - IB - initial balance, under invite-only in TradingView) can draw it for you automatically instead of you marking the levels by hand. set:

the indicator then plots the IB high, IB low, and 50% midpoint for that exact window as it forms.

to see the session box itself on your chart — so you can tell at a glance whether a break landed inside the window — add the market sessions indicator and point one of its sessions at your custom range. that draws the box the IB lives inside, which is especially helpful on an afternoon window where you're watching for the break before the session ends.

a very short or unusual window (a 10-minute balance, an afternoon block, an off-hours session) is completely valid to measure — just keep an eye on how many days actually qualify over your lookback. the shorter and more specific the window, the more a longer lookback helps keep the sample meaningful. the numbers are only as trustworthy as the sample behind them.
