OPEN-SOURCE SCRIPT
OB + SD MTF Overlap
# OB + SD MTF Overlap
## Overview
Most order block and supply/demand tools draw zones for a single timeframe. That
forces you to flip between charts to know whether the level you are looking at also
matters on the higher timeframes — and by the time you flip back, the reaction is over.
This script merges **two different zone engines** — Volumized Order Blocks and
Supply & Demand — and renders both across **up to six timeframes at once** on a single
chart. Instead of a wall of boxes, it encodes the important part as **color intensity**:
the more confluence at a price level, and the higher the timeframe it comes from, the
more opaque the zone. One glance tells you which levels are worth your attention.
## How the zones are detected
The script runs two independent detection engines. They never mix with each other:
an order block is only ever merged with another order block of the same direction, and
a demand zone only with another demand zone.
**Order Blocks (structure based).** A swing high/low is confirmed with a configurable
swing length (default 10). When a close breaks that swing, the script walks back through
the impulse to find the origin candle — the lowest low before a bullish break, the
highest high before a bearish one — and marks that candle's range as the zone. Zones
larger than 3.5×ATR(10) are discarded as noise. Each block also stores the volume of the
three candles that produced the break, split into buy-side and sell-side, and displays
the total plus an imbalance percentage (for example `24.657M (32%)`). A low percentage
means the break was one-sided; a high percentage means it was contested.
**Supply & Demand (momentum based).** When four consecutive candles print bodies larger
than half the 20-period average body in the same direction, the script marks the base
candle that preceded the burst. These zones are clamped to 1.5×ATR(20) so a single wide
candle cannot produce an oversized area, and a minimum spacing of 5 bars prevents the
same move from generating a cluster of near-identical zones.
**Invalidation** is configurable per engine: by wick or by close. Broken zones can stay
on the chart as historical reference or be hidden.
## The overlap and intensity system
Every enabled timeframe is scanned independently, and zones of the same kind and
direction that overlap in price are fused into a single box. The merged zone keeps the
union of the price range, inherits the identity of the **highest** timeframe involved,
and carries a counter of how many original zones it absorbed — shown as `xN` in the label
along with the timeframes it came from, e.g. `1 Hour & 15 Min OB x2`.
Opacity is then computed from two terms:
```
transparency = base − (timeframe rank × tf step) − ((overlap count − 1) × overlap step)
```
clamped to a configurable floor. In practice: a lone 15-minute zone is barely tinted,
while a cluster where the 15m, 1h and 4h all agree is strongly saturated. All four
constants are exposed in the *Color Intensity* settings group, so you can make the effect
subtle or dramatic.
## Auto MTF
With **Auto MTF** enabled (default) the script ignores the manual slots and follows the
chart: it uses the current timeframe plus the next three standard ones above it. On a 5m
chart you get 5m, 15m, 1h and 4h; on a 4h chart you get 4h, D, W and M. Change the chart
timeframe and the zone set re-scales with it — no reconfiguration.
Turn Auto MTF off to drive the six slots manually. In both modes, timeframes lower than
the chart's and duplicate slots are disabled automatically.
## Retests, breaks and alerts
An **R** label marks each time price returns to a live zone (with a cooldown so a single
extended visit does not produce a stack of labels), and an optional **B** label marks the
bar where a zone is invalidated. Labels are cleaned up when their zone disappears.
Eight alert conditions are available: retest and break, for supply, demand, bullish OB
and bearish OB.
## Settings worth knowing
- **Max Distance To Last Bar** — how much history is processed. Lower it if the script
is slow on your machine, especially with six timeframes enabled.
- **OB / S&D Zone Count** — zones kept per type, per timeframe (One / Low / Medium / High).
This is the main control over chart clutter and object count.
- **Swing Length** — smaller values produce more, smaller order blocks.
- **Order Blocks / Supply & Demand** — either engine can be switched off entirely.
- **OB Volume Text** — hides the volume and imbalance line if you only want the boxes.
## How to use it
Treat it as a **map, not a trigger**. The zones tell you where imbalance was created and
where price may react; they say nothing on their own about direction or timing. A
practical reading order:
1. Prioritise the darkest boxes — high timeframe, high overlap.
2. Prefer zones with few or no `R` labels; each retest consumes whatever resting interest
the level held.
3. Use the volume imbalance to tell a decisive origin from a contested one.
4. Wait for your own confirmation *inside* the zone (rejection, absorption, a signal from
another tool) rather than trading the touch itself.
On lower timeframes price interacts with some zone almost constantly, so a zone touch
by itself is a very weak piece of evidence. The value of this script is in showing you
where several independent readings of the market point at the same price — and in letting
you ignore the rest.

What this version adds over the originals: both engines running side by side in one
script; multi-timeframe support extended to the Order Block engine (the original was
chart-timeframe only); the overlap counter and the timeframe/confluence based opacity
model; Auto MTF; retest and break labels unified across both engines; and the removal
of the internal volume bars in favour of a cleaner multi-timeframe view.
