请教前辈: 下列飞狐公式代码如何在AB中实现?

请教前辈: 下列飞狐公式代码如何在AB中实现? 多谢!

RSI1:"RSI#MIN5",LINETHICK0; {5分钟K线的RSI}
RSI2:"RSI#MIN15",LINETHICK0; {15分钟K线的RSI}

DRAWICON(RSI2<30 AND CROSS(RSI1,RSI2),RSI2*0.995,4); {上穿标指示箭头}
DRAWICON(RSI2>70 AND CROSS(RSI2,RSI1),RSI2*1.005,5); {下穿标指示箭头}
n1;n2

 

pd=Param("RSI Period",9,1,30);
TimeFrameSet( in5Minute);
RSIshort =RSI(pd);
TimeFrameRestore();

TimeFrameSet( in15Minute);
RSIlong = RSI(pd);
TimeFrameRestore();

// plot expanded RSI
RSI1=TimeFrameExpand( RSIshort, in5Minute);
RSI2=TimeFrameExpand( RSIlong, in15Minute);
Plot( RSI1, "5 min rsi", colorBlue,5 );
Plot( RSI2, "15 min rsi", colorRed,5 );


B=Cross(RSI1,RSI2) AND RSI2<30;
S=Cross(RSI2,RSI1) AND RSI2>70;

//plot the arrow indications
PlotShapes(shapeSmallUpTriangle*B,colorYellow,0,RSI2,0);
PlotShapes(shapeSmallDownTriangle*S,colorYellow,0,RSI2,0);

Plot(30,"",1,32);
Plot(70,"",7,1);
Plot(50,"",2,32);

 

非常感谢"hgy"的帮助。另外，若引入其它品种，如“道琼斯指数期货”，应如何写？　再次感谢！

 

"道琼斯指数期货" - IB的
YM JUN 08-ECBOT-FUT
有IB的接口直接看就好了

公式引用第三方数据：
close=Foreign( "YM JUN 08-ECBOT-FUT", "Close" ) ;

 

谢谢!
