1st day of a month

[jozef.r]

Hi,

is it possible to check whether 1,2 or 3 days ago it was different month from the current month (i.e. whether it is 1-3 business day of a current month)?

I only want to trade during first 3 business days of a month, if possible.

Thanks for an answer, Jozef

Hello jozef.r,

Thank you for your post and welcome to the NinjaTrader Support Forum!

You can use Bars.GetDayBar(int).Time.Day to pull the day of a previous day bar.

So you could use Bars.GetDayBar(1).Time.Day for yesterday's date. You would then need to figure a check to see if 1,2, or 3 days ago = the last trading day of the previous month.

For information on Bars.GetDayBar() please visit the following link: http://www.ninjatrader.com/support/h.../getdaybar.htm

Please let me know if I may be of further assistance.

Now, a follow-up question would be:

Why the following script would not work?

protected override void OnBarUpdate()
{ if (!(Bars.GetDayBar(3).Time.Month==Bars.GetDayBar(0) .Time.Month)) {
// Condition set 1
if ((CrossAbove(Close, SMA(60), 1)) & )
{
EnterLong(DefaultQuantity, "");
}

// Condition set 2
if (CrossBelow(Close, SMA(60), 1))
{
ExitLong("", "");
}
}
}

Hello Jozef,

Thank you for your response.

Please try the following:

if (Bars.GetDayBar(3).Time.Month!=Bars.GetDayBar(0) .Time.Month)

Please let me know if I may be of further assistance.

[jozef.r]

still, does not seem to work.

here is the entire strategy:

protected override void Initialize()
{

CalculateOnBarClose = true;
}

/// <summary>
/// Called on each bar update event (incoming tick)
/// </summary>
protected override void OnBarUpdate()
{ if ((Bars.GetDayBar(3).Time.Month!=Bars.GetDayBar(0). Time.Month)) {
// Condition set 1
if ((CrossAbove(Close, SMA(60), 1)) & )
{
EnterLong(DefaultQuantity, "");
}

// Condition set 2
if (CrossBelow(Close, SMA(60), 1))
{
ExitLong("", "");
}
}
}

#region Properties
[Description("")]
[GridCategory("Parameters")]
public int MA1
{
get { return mA1; }
set { mA1 = Math.Max(1, value); }
}

[Description("")]
[GridCategory("Parameters")]
public int MA60
{
get { return mA60; }
set { mA60 = Math.Max(60, value); }
}
#endregion
}

Hello Jozef,

Thank you for your response.

Is the strategy not taking positions? Are you receiving any error messages?

I look forward to your response.

[jozef.r]

no positions taken.

no error messages.

Hello Jozef,

Thank you for your response.

That would be my mistake as I set the condition to check if the two dates month do not match and then enter positions. We need the opposite of this.

Please use the following code:

if (Bars.GetDayBar(3).Time.Month==Bars.GetDayBar(0) .Time.Month)

[jozef.r]

no, i only want to take positions during first 3 days of a month, so the original condition was correct. but i do not know why no trades.

Hello Jozef,

Thank you for your patience.

I had to test this one on my end a little further and I found the proper condition to be the following:

if (Bars.GetDayBar(3) != null && Bars.GetDayBar(3).Time.Month != Time[0].Month)

We have to check that there is a value 3 days ago and we must use Time[0].Month to access the current bar's month (this month).

Please let me know if I may be of further assistance.
