Anthony,

Periods=Param("periods",260,1,260,1);

Topbox=IIf(Ref(H,-3)>=Ref(HHV(H,Periods),-4) AND Ref(H,-2)<Ref(H,-3) AND Ref(H,-1)<Ref(H,-3) AND H< Ref(H,-3),Ref(H,-3),PREVIOUS);

Plot(Topbox,"Topbox",colorRed,1);

Botbox=IIf(Ref(H,-3)>=Ref(HHV(H,Periods),-4) AND

Ref(H,-2)<Ref(H,-3) AND Ref(H,-1)<Ref(H,-3) AND H< Ref(H,-3),LLV(L,4),PREVIOUS);

Plot(Botbox,"Botbox",colorGreen,1);

That's the code but I don't know "PREVIOUS" what they prefer to!!!

Tom,

Try this:

Cond=L > Ref(L,-1) AND H > Ref(H,-1);

Cond2=BarsSince(Cond < 1);

Filter=1;

AddColumn(Cond2,"");

Is it possible to have Higher Highs AND Higher Lows show at the same time.

Thank you

Tom

Anthony,

Again, thank you. What I am trying to determine is how many days in a row the stock is setting higher highs and higher lows, as opposed to a moving average. Is this possible to code?

Tom,

You have yet to define what you consider as trending....here is another sample:

periods=Param("periods",10,1,100,1);//N period moving average

trendingup=BarsSince(L < MA(L,periods));

trendingdown=BarsSince(H > MA(H,periods));

Filter=1;

AddColumn(trendingup,"up",1);

AddColumn(trendingdown,"down",1);

Thank you. I ran your script and realized that I asked the wrong question. What I am trying to determine is if the price has been in a "continuous" up or down trend for n periods.

Depends on how you want to define trending Higher or lower..Here is a sample explore...

//Automatic analysis

//Explore

//all symbols

//n last quotations

//n=1

periods=10;

trending=ROC(C,periods);

trendingUP=trending > 0;

trendingDown=trending < 0;

state=WriteIf(trendingup,"trendingUP for ("+WriteVal(periods,1)+") periods ","trendingdown for ("+WriteVal(periods,1)+")periods");

Filter=1;

AddTextColumn(state,"State");

Would someone be able to tell me how to write a condition to a scan that says 'if prices are trending either higher or lower for n periods'?

Thank you

Tom
