Syntax Errors

[sam11976]

This issue was dealt with in another thread, however, the answers I was receiving took the wrong path. I need a new person to look/compile this script and get it co compile. I received several answers and none of them worked. This should be something simple, however, there are syntax error that error msgs that are not providing leads to where to go.

I downloaded the script after updating the last answer which was the following (I added it but do not understand that section).
[GridCategory("Parameters")]
public int DmiPeriods
{
get { return dmiPeriods; }
set { fast = Math.Max(1, value); }
}



Another simple question on unrelated note:

I tried to add a condition:
if (DM(DmiPeriods).DiPlus >= 20)

error msg that I cant compare this variable to numeric value!!!

how can I get around that?

Thanks.

Sam, the script attached will compile - you would need to add the public property for your DMI value under 'Properties' in the script, not in the Strategy name space.

thanks.

the 2nd part of the question, I want to add this condition but syntax not allowed:
&& ((DM(BarsArray[1],DmiPeriods).DiPlus >= 20))

[NinjaTrader_Bertrand]

Please try comparing a double to a double, so 20.0 - would that compile?

[sam11976]

does not compile. u can test this? right?

[NinjaTrader_Bertrand]

Sorry, then please then this - && ((DM(BarsArray[1],DmiPeriods).DiPlus[0] >= 20.0)))

You missed getting a double value from your DiPlus series.

Thanks much. This compiles. One more question:
in this example to reference SMA, I do this
if (SMA(BarsArray[1], Fast)[0] > SMA(BarsArray[1], Slow)[0] -----

how I reference CLOSE in the array? Thanks again. I am getting there..

[NinjaTrader_Bertrand]

You're welcome, with BarsArray you access the Close value actually, you could also directly use Closes -
