Frankfurt IB for London Open - GER40 & UK100

What this script does

This tool builds a precise pre-London “Initial Balance” (IB) for European index trading. It measures the **Frankfurt pre-London window** — the 60 minutes immediately **before** the London cash open — and plots:

- the **High** and **Low** of that window, and
- the **Midline (0.5)** of that range

These levels are extended into the London session so traders can execute a structured London-open playbook on **GER40** (also works on **UK100** and similar European indices)

Why this matters

Liquidity typically increases around the London open. By treating the Frankfurt pre-London window as an **Initial Balance**, the script provides an objective opening framework: continuation through a clean break and hold, or a failed break leading to mean-reversion. The plotted IB and its 0.5 line standardize entries, invalidation, and management

[b]How it works (calculation logic)

1. At the user-defined **London Open** time, the script looks back **60 minutes** (configurable) to define the **Frankfurt window**.
2. It computes the **range High/Low** of that window and the **Midline (0.5)**.
3. It draws/extends those levels forward into the London session for trade decision-making.

The script uses time and OHLC from the chart’s exchange timezone. It does not use future data and does not repaint past values; once the window closes, the IB levels are fixed for that day

Recommended timeframe

Designed for **2-minute charts** for entries and confirmations. Higher timeframes can be used for context, but the triggers below are defined on 2-minute bars

Entry playbooks (three variants)

1. **Break & Hold without mid retest**
- Condition: Two consecutive **2-minute closes** outside the Frankfurt IB (above the High for longs or below the Low for shorts), **without** any prior retest of the **0.5** midline after London open.
- Rationale: Strong continuation through the boundary signals momentum; absence of a midline rebalancing means confirmation must be stricter (two closes)

1. **Break & Hold after a mid retest**
- Condition: A **single 2-minute close** outside the IB boundary **after** price has **retested the 0.5 midline** post-open.
- Rationale: The midline retest suggests the range has rebalanced; therefore, fewer confirmations are required (one close suffices)

1. **Failed Break Reversal (raid & reject)**
- Condition: Price **probes** beyond an IB boundary but **fails to hold** (no 2-minute close maintained beyond the boundary), then prints a **clear rejection/confirmation** back inside the range **before** reaching the **0.5** midline.
- Execution note: The management guideline here is conservative — if price subsequently tags the **0.5** midline, shift risk to break-even according to the playbook

Risk management heuristics

- **Invalidation** typically sits just beyond the opposite side of the confirming 2-minute structure.
- On **Variant 3** (reversal), consider moving to **break-even** upon touch of the **0.5** midline, as this aligns with the mean-reversion objective.
- Avoid chasing late breaks far from the IB boundary; the framework is built for opening structure, not extended moves

Examples:

1. **Break & Hold without mid retest**


2. **Break & Hold after a mid retest**




Scope & originality

While it uses classic session/range concepts, the script packages a **specific European opening routine** into a reproducible execution framework: a fixed pre-London IB, a midline-based rebalancing rule, and **three explicit 2-minute confirmation variants**. This codifies a niche London-open methodology for **GER40/UK100** that is not available in built-ins and aims to add practical value in live execution.

Limitations

- This tool does **not** generate signals from indicators like RSI/EMA; it purely structures **time-based opening ranges** and **rule-based confirmations** at London open.
- Works best on liquid European index feeds around the open; thin or off-hours data can distort the IB.
