insteed of BeginDay will be EndDay.

thanks

there are any comment to NT7 help

I'm a beginner in programmig and my english knowledge isn't good, so it may happend I coudn't understand all text right. but I found them during translate the help and would be my questions to this:

1. in BoolSeries Class, DateTimeSeries Class in .Set part there are: The following code samples demonstrates calculating the range of each bar and storing the value in a BoolSeries object. is it right?
2. in FloatSeriesin part FloatSeries.Set(floatvalue) at the example:float range = (float) High[0] - Low[0]; sholud be: (float) (High[0] - Low[0]); and FloatSeries.Set(intbarsAgo, boolvalue) is it realy bool value? not float? this situation is tha same at IntSeries.Set(intbarsAgo, boolvalue)?
3. in the NT7 Features & Development Status can be read:Changed Volume from type "int" to type "long". in the help can find int yet.
4. in the NT7 Features & Development Status can be read:New Account Access - We added methods to get access to live brokerage account values such as cash balance. - I haven't yet found this section. where can I read about it? it would be important to read about it. there are some methods and properties to this especially to Gain account? e.t.c balance, avg. price, margin, used Lot...
5. in GetCurrentAsk() section instead of subsituted would be right substitute?
6. 
   I won't be a fault-finder but the style and grammar of the help its (very) difficult for me to understand proper everything.

thanks: Tamás

1. Unfortunately I did not quite understand your question. The .Set is used in storing values in any of the _____Series classes. So that does apply to BoolSeries and DateTimeSeries and any others.

2. You are correct. Thank you. It should be "float value".

3. Volumes have indeed been changed from "int" to "long". You can find an example of this in GetCurrentAskVolume() and GetCurrentBidVolume().

4. The section is called GetAccountValue(). It currently does not have any documentation yet.

5. You are right. Thank you.

6. Please bear in mind that the NT7 documentation is a Work In Progress. For most documentation needs you may find it easier to refer to NT6.5 documentation at this point in time.

re:Help

Hi Josh,

thanks for your answer. It's a little complicated quite understandably draft for me. I am sorry for it.
in the #1. point I wanted to explain:
there is in the help:

BoolSeries.Set(boolvalue)
Setting a value on a BoolSeries object is automatically aligned to the current bar being evaluated. This ensures values across all BoolSeries objects are always in sync by the CurrentBar index. The following code samples demonstrates calculating the range of each bar and storing the value in a BoolSeries object.

protected override void OnBarUpdate()
{
// Is the close > than the open
myBoolSeries.Set(Close[0] > Open[0] ? true : false);
}

is it possible it is said if Close[0] > Open[0] to be a range? (I refer the text in red above). I can't find the right word to this in my language. we use another expression.
#4. how can you see, when we can get methods and properties of Account access for connect Gain?

thanks in advance. Tamás

Hi Tamás,

The text in red would be a typo. Thank you for making us aware of it. Close[0] > Open[0] just checks if the close is greater than the open. If it is, we assign a true value to the BoolSeries, otherwise, we assign a false value.

#4. You can try these:
For Buying Power: GetAccountValue(AccountItem.BuyingPower)
For Cash Value: GetAccountValue(AccountItem.CashValue)
For Realized PnL: GetAccountValue(AccountItem.RealizedProfitLoss)

hello Josh!
Many thanks for answer.

LowestBar()

Hello,

there is an observation in help:
in the LowestBar() section the exemples is:
Print(HighestBar(SMA(20), Bars.BarsSinceSession - 1).ToString());
Insteed of HighestBar should be LowestBar.

Thanks. have a good weekend!

[NinjaTrader_JoshP]

Thanks for bringing this to our attention. This is a typo.

[marotom]

Hello,

I've found tiny typo in NT7 help:
- in Slope() section: at Parameters list:endBar insteed of endBarsAgo
- in Falling() section: at (Falling(SMA(20)) miss at the and a ) signal.
- in Rising() section: at (Rising(SMA(20)) miss at the and a ) signal.

other question.: can be used LRO and MRO with indicators? if yes, how should I write the syntax?

thanks for correction and answer.
by.

[NinjaTrader_JoshP]

Thanks for the spot marotom.

You can use LRO and MRO in indicator logic. All you need to do is call the method as seen in the examples in Help Guide.

int barsAgo = MRO(delegate {return Close[0] > Open[0];}, 1, 10);

[marotom]

Hello Josh,

thanks for answer. therefore I asked because it doesen't work the same logic with LRO. this is my example:
it works:
int barsAgo2 = MRO(delegate {return SMA(14)[0] > SMA(14)[1];}, 2, 30);
if (barsAgo2 > -1)
Print("The bar high was SMA_MRO: " + CurrentBar + " " +" Num: " + barsAgo2 + " High :" + High[barsAgo2]);

but it doesen't work. nothing happend..
int barsAgo4 = LRO(delegate {return SMA(14)[0] > SMA(14)[1];}, 2, 30);
if (barsAgo4 > -1)
Print("The bar high was SMA_LRO: " + " Num: " + barsAgo4 + " High :" + High[barsAgo4]);

I haven't glue what can be the problem. could you me help?

thanks in advance. Tamás

[NinjaTrader_JoshP]

Try printing barsAgo directly without a filter check. You will likely find it to be a value of -1. When it is -1 it means your test condition was not true when evaluated through that look back period.

[KBJ]

this is my example:
it works:
int barsAgo2 = MRO(delegate {return SMA(14)[0] > SMA(14)[1];}, 2, 30);
if (barsAgo2 > -1)
Print("The bar high was SMA_MRO: " + CurrentBar + " " +" Num: " + barsAgo2 + " High :" + High[barsAgo2]);

but it doesen't work. nothing happened..

Each of these examples references "SMA(14)[1]", so you might try doing the following statement first:

if (CurrentBar < 1) return;

Or, perhaps this would work:

int barsAgo2 = (CurrentBar < 1) ? -1 : MRO(delegate {return SMA(14)[0] > SMA(14)[1];}, 2, 30);
