Hard code instrument to trade

[carlosgutierrez]

Hi,
I am modifying my code to trade a fixed instrument which will be hard coded in the script. I am doing this so I can share the script and it would become useless with contract rollover.
The strategy works with ninzaRenko bars, but when I start to AddDataSeriesType, I do not have in the list the ninzarenko option.
How can I add the data series so I can be able to hard code it? The instrument to be hard coded is MNQ 03-24


Appreciate the help!

Thanks bltdavid! very helpful.

How about locking the instrument to trade? Would you know/]have references for this?

Hello carlosgutierrez,

By using the instrument name in the AddDataSeries() call, BarsInProgress 1 will always be that instrument.
When using 1 as the barsInProgressIndex parameter to the order method, that order will always be submitted to that series instrument.

Hi Chelsea,
I currently have :::
protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 1)
return;

Should it be :::


protected override void OnBarUpdate()
{
if (BarsInProgress == 1)
return;

if (CurrentBars[0] < 1)
return;

Hello carlosgutierrez,

I am referring to the barsInProgressIndex supplied to the order method, which sets the series the order is placed to.

EnterLong(int barsInProgressIndex, int quantity, string signalName)

Changed it and does not seem to block the instruement, this is part of the code:

protected override void OnStateChange()
{
if (State == State.SetDefaults)

if (State == State.Configure)
{
AddDataSeries(new BarsPeriod()
{
BarsPeriodType = (BarsPeriodType)12345,
Value = 50,
Value2 = 1
}
);

AddDataSeries("MNQ 03-24");
}



protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 1)
return;

// Set 1- in this set we get the conditions for getting into a long trade. and set the trailing stop loss for the runner position.
if (Close[0] >= Open[0])

{

EnterLong(1, Convert.ToInt32(ScalpingPosition), @"Long1");

}

Hello carlosgutierrez,

You have called AddDataSeries() twice. This means the MNQ 03-24 series will be barsInProgressIndex 2.

EnterLong(2, Convert.ToInt32(ScalpingPosition), @"Long1");

[carlosgutierrez]

as always, amazing support

Thanks!

Final question,
How can I disable the properties to uneditable by the user in the parameter window?

to have the row look like this and not make it possible to change it.



Also, I would like to remove some options from the parameter window. How can I remove them from it with out breaking it?

Currently I am trying the following

*/
[NinjaScriptProperty]
[Range(1, int.MaxValue)]
[Display(Name="Period", Order=1, GroupName="Settings")]
public int Period
{ get; set; }

[NinjaScriptProperty]
[Range(0, double.MaxValue)]
[Display(Name="Multiplier", Order=2, GroupName="Settings")]
public double Multiplier
{ get; set; }

[NinjaScriptProperty]
[Range(1, int.MaxValue)]
[Display(Name="Smooth", Order=3, GroupName="Settings")]
public int Smooth
{ get; set; }


*/


And get the following:

To comment those lines out, you should use the
two character string '//' in front of each line.

After you comment them out, you'll need to
stop using those properties completely in
your code (that's where those error msgs
are probably coming from) because those
properties no longer exist, because, duh,
you've commented them out.

-=o=-

If you still want to use the properties, but just
want to prevent the user from changing the
value, that's possible, too.

To do that, you need to make those properties
readonly -- which means they remain visible
in the property grid, but any changes to the
values by the user are ignored by your
NinjaScript object. 'Readonly' is kinda like
making the property 'greyed-out' in the grid.

To do this, you'll need to do two things.

1. Remove the [NinjaScriptProperty]
from each of the 3 properties.

2. Change the { get; set; } for each of
those 3 properties to a private set, like this,
{ get; private set; }

-=o=-

Note that:
[NinjaScriptProperty] and private set
are mutually exclusive, because of the magic auto
generated code at the bottom of the indicator.

But, since this is a Strategy object, and strategies
do not have auto generated code, you might be able
to use them together in a strategy. That is, you may
not have to remove (or comment out) the
[NinjaScriptProperty] line.

I'm not sure what the optimization mode in Strategy
Analyzer will do, it has to be able to set the property
value to optimize it, so you'll have to check that yourself.
(I suspect private set variables will be greyed-out in
the Strategy Analyzer optimization mode.)

More information on readonly properties is here.

(Btw, if that link doesn't work for you, then try Firefox.
It is valid and created correctly -- Chrome & Edge
sometimes have problems with NT forum links, but
I've never seen FireFox fail.)

That's a little more complicated.
