Yuki,
this code is a slight modification of an example of comparative relative
strenght that Tomasz gave I don't remember where (the man?).
It plots the current ticker in percentage terms against a small set of
indexes. You can focus the period you need to look at via zooming or
using the Focus parameter.
startpoint = Status("barvisible");
period = Param("Focus", 1, 1, 250, 1);
startpoint = startpoint - Ref( startpoint, -period );
price = Close;
Plot( 100 * ( price/ValueWhen( startpoint, price ) - 1 ), Name(),colorBlue);
ticker = ParamStr("Ticker 1", "^GSPC" );
price = Foreign( ticker, "C");
Plot( 100 * ( price/ValueWhen( startpoint, price ) - 1 ), ticker,colorRed );
ticker = ParamStr("Ticker 2", "^RUA" );
price = Foreign( ticker, "C");
Plot( 100 * ( price/ValueWhen( startpoint, price ) - 1 ),
ticker,colorGreen );
ticker = ParamStr("Ticker 3", "^SGX" );
price = Foreign( ticker, "C");
Plot( 100 * ( price/ValueWhen( startpoint, price ) - 1 ),
ticker,colorBrown );
ticker = ParamStr("Ticker 4", "^SVX" );
price = Foreign( ticker, "C");
Plot( 100 * ( price/ValueWhen( startpoint, price ) - 1 ),
ticker,colorDarkYellow );
GraphXSpace = 3;
This is the same code modified for taking into account different time
periods (to a year) in months terms.
period = Param("RS months", 1, 1, 12, 1);
RS_Period = period*20;
price = ROC(Close, RS_Period);
index = ParamStr("Ticker 1", "^GSPC" );
RS = price - ROC(Foreign( index, "C"), RS_Period);
Plot( RS, index,colorRed );
index = ParamStr("Ticker 2", "^RUA" );
RS = price - ROC(Foreign( index, "C"), RS_Period);
Plot( RS, index,colorGreen );
index = ParamStr("Ticker 3", "^SGX" );
RS = price - ROC(Foreign( index, "C"), RS_Period);
Plot(RS, index,colorBrown );
index = ParamStr("Ticker 4", "^SVX" );
RS = price - ROC(Foreign( index, "C"), RS_Period);
Plot( RS, index,colorDarkYellow );
GraphXSpace = 3;
You will see that the most intuitive is the first one. Imo it's better
to look at the comparative relative strenght of a set of indexes with
different time periods in AA via Explore.
