BT Ligma

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.
