Strategy does not start

[iskip]

Heeeelp !
The strategy takes off at the beginning of the current code :

protected override void OnBarUpdate()
{

// Enter for 1st Enter
if (//Bars.BarsSinceSession < 50 &&
N_3 == 1 &&
Close[0] > Open[0] &&
CrossAbove(SMA(7), SMA(14), 2)
)

{
N=1;
SetProfitTarget("", CalculationMode.Ticks, TP);
SetStopLoss("", CalculationMode.Ticks, SL, false);
EnterLong(N, "");
N_3 = 2;
}

// Enter Long if LastWin
if (//Bars.BarsSinceSession > 50 &&
N_3 != 1 &&
Performance.AllTrades[Performance.AllTrades.Count - 1].ProfitCurrency > 0 &&
Close[0] > Open[0] &&
Position.MarketPosition != MarketPosition.Long &&
Position.MarketPosition != MarketPosition.Short &&
CrossAbove(SMA(7), SMA(14), 2)
)
{
N=1;
SetProfitTarget("", CalculationMode.Ticks, TP);
SetStopLoss("", CalculationMode.Ticks, SL, false);
EnterLong(N, "");
}


It compiles okay.
N_3 =1 (int)
If make via : Bars.BarsSinceSession < 50
and here and there , all running at 50 pc , at < 40 - no.
I do not want to lose the bars since the beginning of the session.
What 's the problem ?

Hello,

I am sorry but I do not fully understand the question.

You said:

If make via : Bars.BarsSinceSession < 50
and here and there , all running at 50 pc , at < 40 - no.
I do not want to lose the bars since the beginning of the session.

Is the condition you created not becoming true when you think it should?

Could you clarify what you are asking?

I look forward to being of further assistance.

If I make like this:
________________________________
protected override void OnBarUpdate()
{
if (N_3 == 1 &&
Close[0] > Open[0] &&
CrossAbove(SMA(7), SMA(14), 2))
{
N=1;
SetProfitTarget("", CalculationMode.Ticks, TP);
SetStopLoss("", CalculationMode.Ticks, SL, false);
EnterLong(N, "");
N_3 = 2;
}

if (N_3 != 1 &&
Performance.AllTrades[Performance.AllTrades.Count - 1].ProfitCurrency > 0 &&
Close[0] > Open[0] &&
Position.MarketPosition != MarketPosition.Long &&
Position.MarketPosition != MarketPosition.Short &&
CrossAbove(SMA(7), SMA(14), 2))
{
N=1;
SetProfitTarget("", CalculationMode.Ticks, TP);
SetStopLoss("", CalculationMode.Ticks, SL, false);
EnterLong(N, "");
}
_____________________________________________

It does not work at all. Compalining, but not starts.
Why?
I just need to make 1st trade close to session start.

Cause all next trades realized over conditions

Performance.AllTrades[Performance.AllTrades.Count - 1].ProfitCurrency > 0
or
Performance.AllTrades[Performance.AllTrades.Count - 1].ProfitCurrency < 0

Hello,

Thank you for the reply.

To know why a condition does not become true, you may need to add Print(); statements to print information on why that is not happening.

An example could be:

Print("N_3 " + N_3 + " &&  " + Close[0] + " > " + Open[0] + " && " + CrossAbove(SMA(7), SMA(14), 2));

if (N_3 == 1 && 
Close[0] > Open[0] &&
CrossAbove(SMA(7), SMA(14), 2))

If you print the value to the Tools -> Output Window, you can see why the condition is not happening on a specific bar to know why.

I look forward to being of further assistance.

Tnx, it's realy comfort to seen reason.

N_3 1 && 2165,5 > 2165,5 && False
N_3 1 && 2165,5 > 2165,5 && False

protected override void OnBarUpdate()

{

SetStopLoss("", CalculationMode.Ticks, SL, false);
EnterLong(N, ""); 
N_3 = 2;
} 

All the rest code is unactive.

But I do not understand what bars he means?

[NinjaTrader_Jesse]

Hello,

Thank you for the reply.

This specific message:

**NT** Error on calling 'OnBarUpdate' method for strategy 'SMAMarti/928847aff6124a84bfcf4ec3637ce286': You are accessing an index with a value that is invalid since its out of range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

May not be related to what you have provided, is this the entire OnBarUpdate region?

This error comes when you use a BarsAgo that does not exist, assume you are on bar 0 and use 1 bar ago. This error would be generated as you need to wait until bar 1 to access 1 bar ago.

Additionally this could happen if you are using a multi series script.

If you can show the rest of the OnBarUpdate section it would be more apparent why this error is happening.

I look forward to being of further assistance.

Hello,

Thank you for that.

I tried this on my end but do not get the same error nor do I see anything that should cause this error.

Could you try removing the instance of this strategy by going to the Control Center -> Strategy tab -> Right click the strategy and select Remove. Do this for all instances of the strategy.

Now re apply the strategy to the chart, do you get the same error?

If you do can you tell me what instrument you are using and timeframe?

I look forward to being of further assistance.

[iskip]

Make all you say. Yes, same error(

[iskip]

sorry sorry sorry

You are right, all working!
Tnx tnx tnx!!!!

[NinjaTrader_Jesse]

Hello,

Thank you for trying that.

I am glad that was the resolution.

In certain cases, depending on that changes you make you may need to remove the instance of the strategy or indicator and then re add it. This is important for any Initialize changes.

I look forward to being of further assistance.
