Example:

bool Inizio=false;

if it's first bar of session daily ===> inizio=true;

how can do it ? thanks

Hello esignal,

Thank you for your note.

You would use the following method to identify the first bar of session, which will return true if so.

if (Bars.IsFirstBarOfSession)

See isfirstbarofsession section of our helpguide.

https://ninjatrader.com/support/helpGuides/nt8/en-us/?isfirstbarofsession.htm

The following would draw an arrow on each bar that was the first bar of session and if the day was the current day.

if (Bars.IsFirstBarOfSession && Time[0].Date == nowDate.Date)
{
    Draw.ArrowDown(this, @"MyCustomStrategy14" + CurrentBar, false, 0, High[0], Brushes.Red);
}

Note, most futures contracts the First Bar of Session is in the previous day so the above condition would be best applied to equities.

Please let us know if you need further assistance.

Excuse me...nowDate what is? ....i can't find it

Another question :

is correct to use :

CurrentDayOHL().High[0]


to have High of this session day? thanks

Hello esignal,

I apologize I left that line of code out in my previous message. nowDate is a DateTime variable set to today.

The full code,

DateTime nowDate =DateTime.Now;

if (Bars.IsFirstBarOfSession && Time[0].Date == nowDate.Date)
{
Draw.ArrowDown(this, @"MyCustomStrategy14" + CurrentBar, false, 0, High[0], Brushes.Red);
}

Link to DateTime.Now,

To get the current sessions high you would use CurrentDayOHL().CurrentHigh[0] rather than CurrentDayOHL().High[0], which will give you the current bars high.

Please let us know if you need further assistance.

Time[0].Date == nowDate.Date

hi..there is another problem

if i do backtest with my strategy don't run correctly because nowDate.Date is time of execution and Time[0].Date is time of candle in chart

Hello Esignal,

If you’d like your strategy to execute or calculate off the first bar of the session, you should just use,

if (Bars.IsFirstBarOfSession)

Please let us know if you need further assistance.

ok..

but if i use it in indicator

example :

if (Bars.IsFirstBarOfSession && Time[0].Date == nowDate.Date)
{
Draw.ArrowDown(this, @"MyCustomStrategy14" + CurrentBar, false, 0, High[0], Brushes.Red);
}

i don't see ArrowDown in historical chart !..

i see only indicator in realtime correctly represented...but not in historical

[NinjaTrader_AlanP]

Hello Esignal,

The reason why the statement below will only be true in real time, is that nowDate.Date will only equal today, even historically.

If you’d like this to work historically you should remove the Time[0].Date == nowDate.Date), so that you are just looking for the first bar of session.

Use,

if (Bars.IsFirstBarOfSession)

Not,

if (Bars.IsFirstBarOfSession && Time[0].Date == nowDate.Date)

I would suggest adding print statements to check whether your conditions are becoming true/what variables equal. I’ve provided a link to a youtube video which covers an example of using prints to understand behavior:

I’ve provided a link covering debugging which you may find helpful.
