1st Hour High/Low

[pijamatrader]

Hi, does anyone know where I can find, or how I can make an indicator that plots a line showing the 1st hour's High/Low of the session?

Thanks,

A system indicator does not exist but you can program one in NinjaScript. If you are new to programming, this will require a learning curve. If you have programming background, please see the Help Guide section for NinjaScript. There are some indicator development tutorials to get you started. You can also look at the code for the PriorDayOHLC to get an idea of how to go about programming the logic for such an indicator.

I am also interested in this indicator.

Is there a function that allows you to store values from a given time/date?

thanks

[NinjaTrader_Ray]

No there is not.

This is the logic I have but would like some help with the translation to get me started.

THanks

// New day settings
if ( DateTime[0]<>Date[1] )
DateInFromTo= (Date>=iFromYYYMMDD && Date<=iToYYYMMDD);
bool FirstTrade=true;
double RangeH=H;
double RangeL=L; // first bars High Low are Ranges h&l
TimeH=Time;
TimeL=Time;


// Range settings
If L<LowD(0)[1] then TimeL=Time; {if new H or L, remember the time of H or L}
If H>HighD(0)[1] then TimeH=Time;

If Time=OpenRangeTime then begin // if openning range is finished
RangeH=HighD(0); RangeL=LowD(0); RangeHtime=TimeH; RangeLtime=TimeL; end; // remember Range parameters

I suggest reviewing some of our system indicator source files. Check out the @PreviousDayOHL to get an idea of how this can be done.

In NT, how do I recall the High or Low of a given time?

Can I declare a variable representing 930am EST and another as 1000a EST as below?

e.g.

private double start_time = 0930;
private double end_time = 1000;

thanks

There seems to be a few requests to the OR lines. So I will start providing my logic. Let me know if it needs to be corrected.

Thanks

I have uploaded part of my code but still getting error messages.

The name 'StartTime' does not exist in the current context
" " 'EndTime' " " " " " " "

Any help in the code is appreciated

thanks

StartTime --> You have not declared this anywhere, that's why it says it does not exist. Even if you rectify this, your logic will not work. Please review the following Help Guide section.

Hi

I changed the code to the following but it still doesn't plot the lines. Any help is appreciated. THe code compiled correctly.

protected override void Initialize()
{
Add(new Plot(Color.Orange, PlotStyle.Line, "PeriodHigh"));
Add(new Plot(Color.Orange, PlotStyle.Line, "PeriodLow"));

AutoScale = false;
CalculateOnBarClose = false; // Call 'OnBarUpdate' on every tick
Overlay = true; // Plots the indicator on top of price
}

protected override void OnBarUpdate()
{
if (currentDate != Time[0].Date)//if new day
{
PeriodHigh = 0; // re-initialize PeriodHigh,PeriodLow for the new day
PeriodLow = 9999;
}
if (ToTime(Time[0]) > start_time && ToTime(Time[0]) < end_time) {
if (High[0] > PeriodHigh) { PeriodHigh = High[0] ; }
if (Low[0] < PeriodLow) { PeriodLow = Low[0] ; }

}
}

Hi,

Its not plotting since you are not setting any plot values. I would scrap this indicator and start through the wizard and add plots named PeriodHigh and PeriodLow and then have the wizard generate all of the code required.

Then add back your logic and when you have to set the value of your plots, you would do something like:

PeriodHigh.Set(plotValueHere);

I think I am very close but I got 1 error message.

Cannot apply indexing with [] to an expression of type 'double'

[NinjaTrader_Ray]

PHigh is a variable not an array that can be indexed.

Should be PeriodHigh.Set(PHigh);

Hi

The code works now but my logic is flawed. How do I use the following properties?

Bars.GetSessionBar(int sessionsAgo).High

Bars.GetSessionBar(int sessionsAgo).Low

Trying to gather the highest high and lowest low of session from start period to end period.

Thanks
