Sunrise Zones

What it does

For each enabled city, the indicator computes the local civil sunrise time every trading day and marks a sunrise zone: the high and low of the 1-minute bar in which that sunrise occurs, projected forward for the city's Keep Days, with an EQ (midpoint) line and a day-age counter.

Detection runs on its own added 1-minute series, so the zone resolves to the true sunrise minute no matter what period your chart is on. A 15-minute chart gets the same zone a 1-minute chart does.

Zone anatomy

Every zone is a band, not a line. The EQ line through the middle is the 50% level of that band, and it is where price most often reacts inside the zone.

Zone strength

Each zone also records how much was actually traded in its sunrise minute, so you can tell a zone worth watching from one that formed in dead air:

• Volume — the sunrise bar's volume.
• RVOL — that volume divided by the average 1-minute volume over the RVOL Lookback bars before it. Dividing through makes cities in very different liquidity comparable to each other.
• Retests — a live count, incremented each time a chart bar overlaps the zone after the previous bar closed fully outside it.

The optional stats table shows, per enabled city: sunrise time in the session timezone, High, Low, Range, Volume with its RVOL multiple, and Retests — always for that city's newest zone. The volume cell is tinted in the city color once RVOL clears the highlight threshold.

Cities

18 preset cities plus 4 custom lat/lng slots. Each has its own Enabled, Color, Sunrise Offset and Keep Days inputs, grouped into Day Sun Cities and Night Sun Cities sections in the dialog.

The seven cities on by default are the Day Sun beginner preset — the day-flow sequence TLV → FRA → LON → RIO → NYC → CHI → SFO. Custom slots add Name, Latitude and Longitude; their timezone is approximated from longitude at 15° per hour.

When each zone forms

Because a sunrise zone is minted at local sunrise, each city drops its zone at a different point in your trading day. These are the two beginner presets in the dialog, with roughly when each one lands in Eastern Time.

The seven cities in bold are the ones enabled out of the box. Read them in order — Tel Aviv, Frankfurt, London, Rio, New York, Chicago, San Francisco — and you have the day-flow sequence: each zone forms a little later than the last, so the chart fills in from overnight through to the US afternoon.

Inputs

Stats table inputs

Per-city inputs

Adding it to a chart

1. Right-click the chart → Indicators… → find ToredaSunriseZones, click Add, set the inputs, click OK.
2. Color inputs shown as #RRGGBB are typed as hex text, e.g. `#6FA8DC`. An invalid value falls back to a default and prints a note in the NinjaScript Output window rather than failing the indicator.
3. Give it history. Zones appear only once a sunrise has been seen on the 1-minute series, so load at least a couple of days of data. Cities whose sunrise falls outside your instrument's session simply produce no zone that day.
4. Enable more cities in their city groups as needed. Each enabled city costs one sunrise calculation per minute bar, which is cheap.

Notes and limitations

• The name-chip buffer is measured in minutes rather than pixels, so it reads as more bars on faster charts.
• Retests count once per closed chart bar, so the count depends on your chart period.
• A city whose timezone or color fails to resolve is disabled on its own with a note in the Output window. The other cities keep working.

For strategy builders

Only seven inputs are reachable from the Strategy Builder: City Roster, Focus City, Session Timezone, Daylight Saving Time, RVOL Lookback, Keep Days Override and Draw Visuals. City Roster (`"NYC,LON,…"`, blank = use the per-city toggles) and Keep Days Override (0 = use each city's own) exist so the Builder never has to touch the 88 per-city inputs.
