Just a little code assist needed for entry filter

[Trader.Jon]

Greets!

This is likely easy ... just cant yet get my head around it. I want to test an entry filter BarsArray==0, NT7, and did get almost there, but cant figure out the final step on how to calculate iGoShortETOPtest so I can test it against iGoShortETOPtotal

// ENTER SHORT WHEN
// (( ETOP #bars) * (ETOP average value for ETOPperiod)) >= (ETOPtotal)
// so.... filter will be iGoShortETOPtest >= iGoShortETOPtotal


// - this section all good to use
private int iGoShortETOPperiod = 5;
[Description("[SHORT Enter] Period Length for ETOP - Minimum 5")]
[GridCategory("[SHORT Enter]eTOP)"]
[Gui.Design.DisplayName ("1.a Period Length for ETOP to GO SHORT")]
public int GoShortETOPperiod
{
get { return iGoShortETOPperiod; }
set { iGoShortETOPperiod = Math.Max(3, value); }
}

private double iGoShortETOPtotal = 0.5;
[Description("[SHORT Enter] TOTAL value for ETOP - Minimum -.5")]
[GridCategory("[SHORT Enter]eTOP)"]
[Gui.Design.DisplayName ("1.b TOTAL value for ETOP to GO SHORT")]
public double GoShortETOPtotal
{
get { return iGoShortETOPtotal; }
set { iGoShortETOPtotal = Math.Max(0.5, value); }
}

private int iGoShortETOPbars = 3;
[Description("[SHORT Enter] #Bars for ETOP - Minimum 3")]
[GridCategory("[SHORT Enter]eTOP)"]
[Gui.Design.DisplayName ("1.c #Bars maximum totaled for ETOP to GO SHORT")]
public int GoShortETOPbars
{
get { return iGoShortETOPbars; }
set { iGoShortETOPbars = Math.Max(3, value); }
}
// --------------------------

//This is the part where my brain is too confused to resolve correctly, and really && annoying me greatly ...
//(btw, 4 decimal places expected in ETOP output) ..
//dataseries setup? double?? OnBarUpdate or OnStartUp ??
// VERY explicit code assist is really needed .. is there more than 1 right answer?

iGoShortETOPtest = (iGoShortETOPbars * (ETOP(iGoShortETOPperiod)[0]))

Thanks mightly for assist!

Hey Trader.Jon,

Sorry, I don't follow what you're looking for. Are you looking for help expressing something in NinjaScript? What is it you're trying to do?

Hi Ryan,

Thanks for the response!

With the code I already posted, I am looking to have a variable 'total' be a (minimum value) filter to compare against the multipled value of ( specific variable # of bars of the MovingAverage 'X' MovingAverage value[0]) ... that value is 'test' and I cant seem to have it compile correctly ...

iGoShortETOPtest = (iGoShortETOPbars * (ETOP(iGoShortETOPperiod)[0]))


I need to find out how to properly code it as a double or a dataseries or both .. for some reason its confusing my head and I cant progress on it, so I need explicit assist, as I read the F1 help to no avail.

Thanks for assist,
Jon

Hi Jon,

A double value is used if don't need a value synced to every bar. A data series is used when you want a value synced to every bar. A tutorial on custom data series is available here:

Ryan,

Respectfully, sending me a link for an indicator tutorial, when I am in a strategy thread, is not helpful. Using the Strategy Wizard has NEVER helped me significantly, and I even paid for and took additional online course (that NT had about 1.5years ago). Those wizards just drive me, lets say, beyond my limits.

These steps lead me to, I hope, the correct resolution .. testing will verify later

trying to resolve this line in the code
sGoShortETOPtest.Set(iGoShortETOPbars * (ETOP(iGoShortETOPperiod)[0]));
because I see this error on compiling
The name 'sGoShortETOPtest' does not exist in the current context,CS0103
I setup a dataseries
private DataSeries sGoShortETOPtest;
and have a different error on compile
Operator '>=' cannot be applied to operands of type 'NinjaTrader.Data.DataSeries' and 'double',NT0019
due to this filter
if (
sGoShortETOPtest >= iGoShortETOPtotal
)

when I try to fix that error by following the F1 help NT0019, with this code
if (
sGoShortETOPtest[0] >= iGoShortETOPtotal[0]
)
compiler responds with
Cannot apply indexing with [] to an expression of type 'double',CS0021
so this now compiles
if (
sGoShortETOPtest[0] >= iGoShortETOPtotal
)

IF you spot something that is an error in my 'fix' please let me know
Jon

Hey Jon,

That looks good. You're comparing two double values by applying indexing to the data series. You can use the indicator data series tutorial in a strategy as well. They're both structured the same way.
