完善后的代码如下：

// 定义指标变量
double DIFF, DEA, MACD, AH, AL, trendline, K, D, J;

// 计算DIFF、DEA、MACD指标
DIFF = iMA(NULL, 0, 12, 0, MODE_EMA, PRICE_CLOSE) - iMA(NULL, 0, 26, 0, MODE_EMA, PRICE_CLOSE);
DEA = iMA(NULL, 0, 9, 0, MODE_EMA, DIFF);
MACD = 2 * (DIFF - DEA / 2);

// 计算AH、AL指标
AH = iHighest(NULL, 0, MODE_MAIN, 13, 1);
AL = iLowest(NULL, 0, MODE_MAIN, 13, 0.3);

// 绘制MACD指标柱状图
PlotIndexSetInteger(0, PLOT_DRAW_BEGIN, Bars-1);
PlotIndexSetString(0, PLOT_ARROW, "Arrow");
PlotIndexSetInteger(0, PLOT_ARROW_SHIFT, 0);

// 绘制趋势线
trendline = iMA(NULL, 0, 34, 1, MODE_EMA, MACD);
PlotIndexSetInteger(1, PLOT_LINE_VALUE, int(trendline));
PlotIndexSetInteger(1, PLOT_LINE_BEGIN, Bars-1);
PlotIndexSetString(1, PLOT_ARROW, "Arrow");
PlotIndexSetInteger(1, PLOT_ARROW_SHIFT, 0);
PlotIndexSetString(1, PLOT_LABEL, "Trend Line");

// 计算K、D、J指标
K = iMA(NULL, 0, 2, 1, MODE_SMA, MACD);
D = iMA(NULL, 0, 2, 1, MODE_SMA, K);
J = iMA(NULL, 0, 2, 1, MODE_SMA, D);

// 绘制K、D、J指标柱状图
PlotIndexSetInteger(2, PLOT_LINE_VALUE, int(K));
PlotIndexSetInteger(2, PLOT_LINE_BEGIN, Bars-1);
PlotIndexSetString(2, PLOT_ARROW, "Arrow");
PlotIndexSetInteger(2, PLOT_ARROW_SHIFT, 0);
PlotIndexSetString(2, PLOT_LABEL, "K");
PlotIndexSetInteger(3, PLOT_LINE_VALUE, int(D));
PlotIndexSetInteger(3, PLOT_LINE_BEGIN, Bars-1);
PlotIndexSetString(3, PLOT_ARROW, "Arrow");
PlotIndexSetInteger(3, PLOT_ARROW_SHIFT, 0);
PlotIndexSetString(3, PLOT_LABEL, "D");
PlotIndexSetInteger(4, PLOT_LINE_VALUE, int(J));
PlotIndexSetInteger(4, PLOT_LINE_BEGIN, Bars-
