# AIMS Bubble EA — Strategy & Methodology Guide

The **AIMS Bubble EA** executes two complementary strategies under a single unified architecture: **Super Stretched Exhaustion Reversals** and **Centre-Band Snap-Back Pullbacks**.

***

## 1. Strategy 1: The Two-Tier Super Exhaustion Reversal[​](#1-strategy-1-the-two-tier-super-exhaustion-reversal "Direct link to 1. Strategy 1: The Two-Tier Super Exhaustion Reversal")

The greatest danger when trading counter-trend exhaustion is fading a high-momentum expansion candle too early. The EA uses a two-tier state machine to guarantee timing precision:



### Setup Rules:[​](#setup-rules "Direct link to Setup Rules:")

1. **Tier 1 (Arming)**: On a completed candle close, price must simultaneously satisfy:

   

   * Keltner Stretch $|E| \ge 2.25$
   * Penetration beyond the 20-period 2.0 SD Bollinger Band
   * Stochastic (5/3/3) $< 20$ (oversold) or $> 80$ (overbought)
   * RSI (14) $< 30$ (oversold) or $> 70$ (overbought)
   * *State is armed for up to 3 bars*.

2. **Tier 2 (Trigger)**: On the next candle, the EA looks for structural recovery:

   

   * For Oversold: First green bar (`Close > Open`), Inside Bar, or Bull Fruit.
   * For Overbought: First red bar (`Close < Open`), Inside Bar, or Bear Fruit.

3. **Execution**:

   

   * Places a `Buy Stop` / `Sell Stop` order with 1-pip buffer.
   * 3-bar order expiration: stale orders are automatically purged.
   * Max ATR Guard: Setup is rejected if the Stop Loss distance exceeds 2.5x ATR.

## 2. Strategy 2: Centre-Band Snap-Back Pullback[​](#2-strategy-2-centre-band-snap-back-pullback "Direct link to 2. Strategy 2: Centre-Band Snap-Back Pullback")

In a strong trending environment, price expands to the outer containment band (`|E| >= 2.25`), exhausts, and pulls back toward the 20 EMA centre band (`|E| <= 1.0`).

When the 20 EMA maintains strong directional slope (`|Slope| >= 0.02`) and a confirmed Fruit candle forms inside the centre band, the EA enters in the direction of the macro trend to ride the next impulse wave.

## 3. Universal Model A (Pure Free Trade) Invariant Standard[​](#3-universal-model-a-pure-free-trade-invariant-standard "Direct link to 3. Universal Model A (Pure Free Trade) Invariant Standard")

Like all 5 flagship AIMS Expert Advisors, `AIMSBubbleEA` enforces the **Universal Model A Architecture**:

1. **50% Realized Profit Bank at +1.0R**: When open profit reaches $+1.0R$ (1x Initial Risk), 50% of the position volume is closed into realized cash profit.
2. **Structural Stop Loss (Zero Premature BE)**: The Stop Loss is never moved to artificial break-even. It remains anchored to the swing climax wick, preventing normal pullbacks from prematurely stopping out profitable trades.
3. **Uncapped Profit Potential**: Zero artificial Take Profit ceiling. Runners are allowed to capture full multi-day macro moves.
4. **Keltner Midline Trailing**: Dynamic trailing stop anchors to the 20 EMA Midline, providing natural trend-riding containment.
