主图指标 mt4指标类型：趋势指标 是否能用在mt4手机版上：否 是否含有未来函数：无 // This indicator is based on the article: Getting Clear With Short-Term Swings by Ron Black // // http://www.traders.com/Documentation/FEEDbk_docs/2010/09/Black.html // http://www.traders.com/Documentation/FEEDbk_docs/2010/09/TradersTips.html // // To set up colored candle charts: // - switch to Line Chart // - in Chart Properties window, set Line Chart Color to None (the entire price graph will disappear) // - copy the ClearMethod.mq4 file to the Indicator directory, it will be used by iCustom() // - add ClearMethodCandles1 (this must be the first), then ClearMethodCandles2 to the chart // - if you use black backgrounded chart, set IsBlackChart parameter to true for both indicator #property indicator_chart_window #property indicator_buffers 3 #property indicator_color1 White #property indicator_color2 C'64, 128, 128' #property indicator_color3 C'128, 64, 128' int maxHistoryBarsToCount = 50000; bool IsPrevBarUpSwing; double PrevBarHighestHigh; double PrevBarLowestHigh; double PrevBarHighestLow; double PrevBarLowestLow; double IsUpSwingBuffer; double UpSwingLineBuffer; double DownSwingLineBuffer; int init() { SetIndexStyle(0, DRAW_NONE); SetIndexBuffer(0, IsUpSwingBuffer); SetIndexStyle(1, DRAW_LINE, STYLE_SOLID, 2); SetIndexBuffer(1, UpSwingLineBuffer); SetIndexStyle(2, DRAW_LINE, STYLE_SOLID, 2); SetIndexBuffer(2, DownSwingLineBuffer); SetIndexEmptyValue(1, 0.0); SetIndexEmptyValue(2, 0.0); IsPrevBarUpSwing = false; PrevBarHighestHigh = High[Bars - 1]; PrevBarLowestHigh = High[Bars - 1]; PrevBarHighestLow = Low[Bars - 1]; PrevBarLowestLow = Low[Bars - 1]; return(0); } int start() { int countedBars = IndicatorCounted(); int countFrom = MathMin(Bars - countedBars - 1, maxHistoryBarsToCount); if (countFrom >= 0 && countFrom < Bars) { countIndicator(countFrom); } return(0); } int countIndicator(int countFrom) { int i; bool isUpSwing = IsPrevBarUpSwing; double highestHigh = PrevBarHighestHigh; double lowestHigh = PrevBarLowestHigh; double highestLow = PrevBarHighestLow; double lowestLow = PrevBarLowestLow; for (i = countFrom; i >= 0; i--) { if (isUpSwing) { highestHigh = MathMax(High, highestHigh); highestLow = MathMax(Low, highestLow); if (High < highestLow) { isUpSwing = false; lowestLow = Low; lowestHigh = High; } } if (!isUpSwing) { lowestLow = MathMin(Low, lowestLow); lowestHigh = MathMin(High, lowestHigh); if (Low > lowestHigh) { isUpSwing = true; highestHigh = High; highestLow = Low; } } if (isUpSwing) { IsUpSwingBuffer = 1.0; UpSwingLineBuffer = highestLow; DownSwingLineBuffer = 0.0; } else { IsUpSwingBuffer = 0.0; UpSwingLineBuffer = 0.0; DownSwingLineBuffer = lowestHigh; } if (i == 1) { IsPrevBarUpSwing = isUpSwing; PrevBarHighestHigh = highestHigh; PrevBarLowestHigh = lowestHigh; PrevBarHighestLow = highestLow; PrevBarLowestLow = lowestLow; } } return(0); } ClearMethod.jpg
