Need help with Daily SMA calculation on primary Tick series

[UltraNIX]

I run my strategy with primary Timeseries - 900 Tick. I have additional Data Series - Daily.

I want to have SMA(30) of Daily Body size. To achieve that, I first created additional series:

if (BarsInProgress == 7) // Daily 
{
                BODY0D[0] = Math.Abs(Close[0] - Open[0]);
                BODY30D = SMA(BODY0D, 30)[0];
}

However, it doesn't work properly, I tried to print BODY0D[1], BODY0D[2], BODY0D[3] values, and they all return 0.

I tried to change code to: BODY0D[0] = Math.Abs(Closes[7] - Opens[7]);, but it does give error: "Operator '-' cannot be applied to operands of type 'NinjaTrader.NinjaScript.PriceSeries' and 'NinjaTrader.NinjaScript.PriceSeries'"
I also get the same error, if I try to change code of BODY30D to BODY30D = SMA(Closes[7] - Opens[7], 30)[0];

So how can I get SMA(30) Of Daily Body working properly with 900 Tick as primary series?

Hello UltraNIX,

Thank you for your inquiry.

Closes[7] - Opens[7] would try to subtract the entire Open Series from the entire Close series - you'd use Closes[7][0]-Opens[7][0] to get the current value of those.

That being said, I've created a simple example script that is working for me. You can test this on a chart with at least 30 days to load - I tested on a 90 day chart.

Do you see values as you would expect with this example?

Thanks in advance; I look forward to assisting you further.

Thanks, it works! I inspected the code, it seems, i was using BODY0D = new Series<double>(this) INSTEAD OF BODY0D = new Series<double>(BarsArray[1], MaximumBarsLookBack.TwoHundredFiftySix);

By the way another question. I get 0, when I try this formula: BODY30D[0] * (29/30)

And it's the (29/30) part that is causing an error. How can I solve it. The idea is to "front-run" indicator calculation (as the "real value" would only be visible on the next daily bar) and use 29/30 from BODY30D[0] + 1/30 * (Math.Abs(Close[0] - CurrentDayOHL(Close).CurrentOpen[0])))

Hello UltraNIX,

Thank you for your reply.

You're likely hitting a casting issue. Try something like this:

double myValue = BODY30D[0] * (29.0/30.0);

Making the integer values into a double by adding a decimal should resolve that and return as you'd expect.

Please let us know if we may be of further assistance to you.
