Study at X time

[FTSE Beater]

Hi all

I have one (hopefully final) question.

I need something to return the value of the upper donchian channel at a set time. In my case 1500.

It may sound simple, but it's really confused me

Thanks

I think this should do it
if((getHour()*100)+getMinute()==1500){
addBand(getValue(your_Donchian_function.UPPER),PS_ SOLID,1,Color.magenta,"1500");
}
I used addBand as an example but you could plot it any other way (ie drawTextRelative, etc).

Solution..

It is much more difficult to "go back in time" to find the exact level you want - after it has passed.

The best solution is to build a system that "records" the levels you want at "1501" - of course recording one bar BACK.

Think of it like a live concert. If you record the whole thing, then wanted to go back to a specific minute and hear what was played - it is much more difficult than recording specific minutes of the concert that are clearly labeled.

Just created a variable.

var DonchUpper1500;

Then, at 1501 on the chart, record the donchian level of the previous 1 minute bar.

As i said in my prior message the condition example I gave you should work.
Attached is an efs that plots the Donchian channel and records its value at 1500 as can be seen in the image below

Hi Both

Thank you very much
It'll give me something to work on

Hi Alex

I've got this error come up from your coding

downloads\donchian_at_1500.efs line 45: Parameter Number 3 of Function drawTextRelative is invalid

This is line 45

drawTextRelative(0,vDonch.getValue(DonchianStudy.UPPER),vDonch.getValue(DonchianStudy.UPPER),Color.white,Color.magenta,Text.BOTTOM|Text.CENTER|Text.BOLD,"Arial",11)

There's no error on the formual output window, only when I load it into the chart
Have a missed something

Mark

Do you have the line defing the donchian channel at the top of the efs?

var vDonchian = new DonchianStudy(20, 0);


or something like that?

Hi David

This is the code

The fp1 and fp2 section has got me a little baffled

My apologies, forgot to add one parameter in drawTextRelative.
Substitute that line with the following

drawTextRelative(0,vDonch.getValue(DonchianStudy.UPPER),vDonch.getValue(DonchianStudy.UPPER),Color.white,Color.magenta,Text.BOTTOM|Text.CENTER|Text.BOLD,"Arial",11,"") 

Alex

PS. I have replaced the original efs with one containing the above correction.

[FTSE Beater]

Thanks Alex
That's got it

Mark

....Ok Now I'm really confused.

This is part of the coding I'm concerned with

if((getHour()*100)+getMinute()==1500){
//drawTextRelative(0,vDonch.getValue(DonchianStudy.L OWER),vDonch.getValue(DonchianStudy.LOWER),Color.w hite,Color.magenta,Text.BOTTOM|Text.CENTER|Text.BO LD,"Arial",11,"")
DUpper=vDonch.getValue(DonchianStudy.UPPER)
DLower=vDonch.getValue(DonchianStudy.LOWER)
debugPrintln(DLower)


//LONG 30min BREAK
if (DUpper > 40 ){
//-DLower) / (DUpper-DLower))) > 0.90 {
debugPrintln("It's fired2")
}
}
//debugPrintln(((close()-DLower) / (DUpper-DLower)))



It says that DUpper isn't defined when I believe it is (Red coloured) and the error is coming on line 53 (Blue coloured). What am I missing

Mark

[Doji3333]

Define the study..

Probably, the Donchian study is not devined in your code.

You need to add..

var vDonch = new DonchianStudy(20,0);

to the top of your file. Thus, defining the study as vDonch and allowing your code to return a value from it.

Hi Brad.

It's go that code. This is what's really confusing. Here's the complete code

}

The debugPrintln(DUpper) returns the right value though

You had a bunch of syntax errors, try this

Hi David

Thank you for amending that
Working fine now
