Below is a formula for a "TCI" that I picked up somewhere but forgot to add
where and who. Used it Intraday for a long time as a filter. Suggestion: you
Programmers that are good enough to write this stuff please put your name
and date in it.
//_SECTION_BEGIN("TCI");
ChannelPeriods = Param("Channel Periods",10,1,50,1);
AvgPeriods = Param("Average Periods",21,1,50,1);
OverBought = Param("Over Bought Line",64,0,100,1);
OverSold = Param("Over Sold Line",-64,-100,0,1);
ColTCI = ParamColor("TCI Line Color",colorBrown);
ColOB = ParamColor("Over Bought Color",colorRed);
ColOS = ParamColor("Over Sold",colorGreen);
XSpace = Param("GraphXSpace",7,0,20,0.5);
n1 = ChannelPeriods; // Channel periods
Default is 10.
n2 = AvgPeriods; // Average periods
Default is 21.
AP = Avg; //Typical Price
ESA = EMA(AP, n1);
D = EMA(abs(AP - ESA), n1);
CI = (AP - ESA) / (0.015 * D);
TCI = EMA(CI, n2);
Plot(TCI,"TCI",ColTCI,1);
Plot(OverBought,"OB Line",ColOB,8+16);//|styleNoLabel);//8+16
Plot(OverSold,"OS Line",ColOS,8+16);//|styleNoLabel);
Plot(n1,"Channel Periods",colorBlue,styleNoLabel |styleNoRescale |
styleNoDraw);
Plot(n2,"Avg Periods",colorBlue,styleNoLabel |styleNoRescale | styleNoDraw);
Plot(0,"0",colorRed,styleNoLabel);
//Plot(100,"",9 ,styleOwnScale | styleArea | styleNoLabel,-5,100);
//Background pane coloring
GraphXSpace = XSpace;
//_SECTION_END();

Subject: [amibroker] True Strength Index
Does anyone have a formula (AFL or any other language) for True
Strength Index. There is an article in June issue of TASC (p.26)
where it's claimed that TSI(C,25,13) is more reliable than Stochastic.
TIA
