mathemat. calculation

[Tradexxx]

hi,

i'd like to calculate the value of ((high - low) * 20%) and additionally overwork this value with other figures.

Using:
int MyInteger =0
MyInteger = ((High [0] - Low [0]) * 20%)

result: error on "CS1525" and others.....

perhaps you can point me in the right way - what's wrong?
thank you very much!

Hello,

If your code looks exactly like the snippet that you posted, then the error is most likely coming from the "20%." You will need to represent 20% numerically in your code (.20).

If the issue persists after making this change, please send me a screenshot of the complete error message, and I will investigate further.

hi Dave,
thank you very much - the %-problem is solved.
i've send you a priv message with the other problems, that do not belong to this topic.
perhaps you can have a look at it ? thx!!

declare in variable region

private DataSeries PRICE;

then use it as follows:

PRICE =new DataSeries(this);
PRICE.Set((High[0]+Low[0])/2);

then plot

hi sumana.m,

thank's for your assistance.
Well, indicator is compilling, but finally not drawing. i'm using:
DrawLine ("MyLine" + CurrentBar, 0 "PRICE" [0], -5, "PRICE" [0], Color.Black
any ideas ?

[NinjaTrader_DaveI]

Hello,

Are you using that exact syntax in your code? If so, the syntax is most likely the cause. I believe what you are looking for is:

DrawLine ("MyLine" + CurrentBar, 0, Close[0] -5, 0, Close[0], Color.Black)

Please see the link below for more information on DrawLine():

Please let me know if I can assist further.

Hi Dave,
thank you very much.
i'm using the drawline expression in another context (tested with strategy wizzard) and it's working there. i just replaced the "Low" expression by using the "price" i wanted to be calculated....
so i guesss it's the syntax that's wrong
attached is the indicator, perhaps someone of you can assist me? thx

sounds like it may work:

DrawLine ("MyLine" + CurrentBar, 0, "Low" [0], -1, "Low" [0], Color.Blue);

Hi Trade

I think I've seen a couple of mistakes from your indicator:

PRICE = new DataSeries (this); needs to be in Initialize and not OnBarUpdate.

In OnBarUpdate, you should code the values as follows, dropping the quotation marks:

DrawLine ("MyLine" + CurrentBar, 0, PRICE[0], -1, PRICE[0], Color.Blue);

Also, your formula may be wrong: do you really mean:

PRICE.Set ((High [0] - Low [0])/2) ???

Being the difference, this would be a figure less than 1 and would be nowhere near the price.

It seems more likely you'd need the average:

PRICE.Set ((High [0] + Low [0])/2);

someone here having a good idea why the indicator isn't working?
attached a overworked version

Hello Tradexxx,

Thank you for your response.


You had if(CurrentBar > 3)return; at the beginning of OnBarUpdate(). If that was not intentional please set it to if(CurrentBar < 3)return; instead.

PatrickH,

thank you very much!
now it's working.
additional question: is there a description for the startcondition (when to use, how to use)?
