Jim,
Here is a solution: use RSIA() function.
You can elimante the Lastvalue(). and when you run explore you will see
the values of RS change..
Bull=9;
Bear=-3;
Trend = IIf(Bull<ROC(EMA(C,50), 14),1,IIf(Bear<ROC(EMA(C,50), 14),2,3));
//xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
B =IIf(Trend == 1,17,IIf(Trend == 2,63, 22));
S =IIf(Trend == 1,58,IIf(Trend == 2,79, 83));
RS=IIf(Trend == 1,14,IIf(Trend == 2,7, 4));
//RS=LastValue(RS);//****Added***/
//RS1=IIf(Trend == 1,14,IIf(Trend == 2,7, 4));
Filter=1;
AddColumn(Trend,"Trend");
AddColumn(B,"B",1);
AddColumn(S,"S",1);
AddColumn(RS,"RS",1);
//AddColumn(ValueWhen(DateNum()==1011018,rs1),"");
AddColumn(ROC(EMA(C,50), 14),"ROC");
StochRsi=EMA((RSIa(RS)-LLV(RSIa(RS),8))/(HHV(RSIa(RS),8)-LLV(RSIa(RS),8)),3)*100;
Buy=Cross(B,StochRsi) AND ADX(14) > 20 AND RSI(4)<50;
Sell=Cross(StochRsi,S)AND ADX(14) > 13 AND RSI(4)>50;
Short=Sell;Cover=Buy;
Plot(Stochrsi,"stochrsi",colorRed,styleLine);
Title=WriteVal(rs);
