How to determine Day Of Month?

[brooksrimes]

I know there is a DayOfWeek function that gives the day of the week (Mon, Tues, etc), but how do you determine Day of the Month in NT?

Example: May 3, 2010 was Day 1 for that month.

P.S. Is there a way to count the number of bars since the month changed ...

I'm trying to detect the 1st trading day of the month, 15th trading day, etc.

Hello brooksrimes,

Unfortunately this is not available in NinjaScript. You would have to custom code this. A C# article that may be useful for you is available at the link below:

Ryan,

Thanks for the suggestion but I don't believe it will work. It doesn't seem to take into account days that the market is closed.

In Amibroker we would code:

TradingDayOfTheMonth = BarsSince( Month() != Ref( Month(), -1 ));

The docs on BarsSince is:

SYNTAX BarsSince( ARRAY )
RETURNS ARRAY
FUNCTION Calculates the number of bars (time periods) that have passed since ARRAY was true (or 1)
EXAMPLE barssince( macd() < 0 )

I've been looking in the NT docs for an equivalent to BarsSince. I see there is a BarsSinceEntry() but that won't do it.

Is there another function I might be unaware of?

Unfortunatley there aren't built in functions that return TradingDayOfMonth or BarsSince. Both would have to be custom coded.

Custom coding BarsSince should be possible by adding to a counter each time the condition is not true and resetting to zero whenever it is true. The snippet below is not supported or tested but should achieve barsSince for you, only when CalculateOnBar close = true.

if (Close[0] > Open[0])
barsSince = 0;

else
barsSince++;
