Hi Found full MT4 code for this.Pl. Code AFL
=========================================================================================================== // This indicator is based on a strategy mentioned in John Carter's book, Mastering the Trade. The basic idea // behind the strategy is that markets tend to move from periods of low volatility to high volatility and // visa versa. The strategy aims to capture moves from low to high volatility. For gauging this he uses two // common indicators - Bollinger Bands and Keltner Channels (ok, not so common!). He also uses the Momentum // indicator to provide a trade bias as soon as the Bollinger Bands come back outside the Keltner Channels. // // The Squeeze_Break indicator combines this into a signal indicator and has the following components: // 1. A positive green histogram means that the Bollinger Bands are outside the Keltner Channels // and the market is lightly to be trending or volatile. The stronger the histogram the stronger // the directional price move. // 2. A negative red histogram means that the Bollinger Bands are inside the Keltner Channels // and the market is lightly to be consolidating. The stronger the red histogram the tighter // price action is becoming. // 3. Incorporated into the indicator is a Momentum indicator. According to the strategy J. Carter // goes long when the Bollinger Bands break outside the Keltner Bands and the Momentum indicator // is above the zero line. He goes short when the Momentum indicator is below the zero line on the // break. // 4. I've also added other indicator info in the top left hand corner to give a broader idea // of current market conditions. // 5. The indicator provides audio alerts when a potential breakout is occurring. // // This indicator tends to be better with the larger timeframes. Personally I don't trade on an alert // signal alone. It's just a handy tool for warning me of potential breakout trades. // =========================================================================================================== #property copyright "DesORegan" #property link "mailto: [email protected]" // ==================== // indicator properties // ==================== #property indicator_separate_window #property indicator_buffers 3 #property indicator_color1 ForestGreen #property indicator_color2 Red #property indicator_color3 Blue // =================== // User Inputs // =================== extern int Boll_Period=20;
