BT Ligma

12月1日

The BT Ligma indicator combines momentum-based signals with volatility filters to identify potential trend reversals and high-probability entry points.

It uses a set of Exponential Moving Averages (EMAs) – typically a fast EMA (e.g., 9-period) crossing over a slower one (e.g., 21-period) – to generate baseline buy/sell signals. These are enhanced by a proprietary "Ligma Spread" filter, which measures the dynamic spread between short-term price action and a volatility envelope (similar to Bollinger Bands but customized with ATR multipliers). This filter helps weed out false signals in choppy markets by requiring a minimum spread threshold before confirming a trade alert.

BT Ligma allows a user to select up to 3 EMAs, the MA calculation method, and signal individual candles that cross EMA 1 & 2, or all 3 bands in the same bar.

Version 1.4, includes refined alert logic, including audio/visual notifications and optional trailing stops based on EMA alignments.

To use it effectively for trade entries:

• Long (Buy) Entries: Look for a bullish EMA crossover (fast EMA above slow) combined with a positive Ligma Spread expansion (indicating increasing momentum). Enter when the signal fires on a close above the recent swing high, ideally on a timeframe like 15m or 1h for scalping/day trading. Pair this with volume confirmation or RSI above 50 to avoid overbought traps.
  
• Short (Sell) Entries: Wait for a bearish EMA crossover (fast below slow) with a contracting or negative Ligma Spread (signaling potential downside volatility). Enter on a close below the recent swing low, using higher timeframes (e.g., 4h) for swing trades to capture larger moves.
  
• General Tips: Always apply risk management – set stops below/above the slow EMA, target 2-3x risk-reward ratios, and avoid trading during low-liquidity periods. Backtest on historical data to tweak parameters, and combine with fundamentals like news events for better context.

# BT Ligma

## Purpose
BT Ligma detects high-intensity reversal candles that cross through key moving averages (9, 21, 55). These “Ligma Events” signal strong momentum shifts and are validated using spread compression, slope trending conditions, and an Aggression Score (LSI). The result is early but reliable reversal confirmation.

## How to Use Ligma in Trading

### 1. Detect Early Reversals
- **L2 = Moderate reversal event**
- **L3 = Strong reversal ignition**

### 2. Validate With Aggression Score (LSI)
- **80–100:** High conviction
- **60–79:** Medium
- **<30:** Usually noise

### 3. Use the Slope Filter
Flat EMAs = weak signals.
Slope filter ensures signals only appear in trending conditions.

### 4. Apply the Spread Filter
Prevents late signals when EMAs are already overextended.

### 5. Integration
Works best with:
- BT MA Bands
- BT Aggression
- BT Stops
- Market structure tools
- VRVP, Keltner, volatility tools

## Trading Notes
- Strongest setups = **L3 + LSI 80+ + Slope OK**
- Weakest = **Low-LSI L2 in flat conditions**
- Ideal for scalping, reversal entries, liquidity sweep confirmations, and momentum shifts.
