SMA on a formula

[naked]

Hello,

I'm getting an error when I try to compile the following:

double VOLRaw = Bollinger(RSIWAvg,2,20).Upper[0] - Bollinger(RSIWAvg,2,20).Lower[0];
SMA VOLRawAvg = SMA(VOLRaw, k_15);


I'm taking the difference between bollingerbands. Then I want to plot the "average difference" of the bollingerbands.

I'm getting hte following errors:

Indicator\AccuSignalVOLATILITY.cs Argument '1': cannot convert from 'double' to 'NinjaTrader.Data.IDataSeries' NT1503 - click for info 133 24

Indicator\AccuSignalVOLATILITY.cs Argument '1': cannot convert from 'double' to 'NinjaTrader.Data.IDataSeries' NT1503 - click for info 133 24


Help! This certainly must be simple to accomplish, but I'm transitioning from EL to C# and I'm having problems figuring it out.

Thanks much

Hello,

Thanks for the forum post:

double VOLRaw = Bollinger(RSIWAvg,2,20).Upper[0] - Bollinger(RSIWAvg,2,20).Lower[0];

This line looks fine at first glance.


SMA VOLRawAvg = SMA(VOLRaw, k_15);

Not sure what your doing with this line though. There are two problems.

You can't difine something of type SMA, also you are missing the [0] at the end of your SMA call. You should define VOLRAWAVG before hand in variables section

double VOLRawAvg;

Should probably look a little more like this:

VOLRawAvg = SMA(VOLRaw, k_15)[0];

Then plot VOLRawAvg.

Let me know if I can be of further assistance.

While you can define a variable to be of type SMA, you will still need to declare it correctly. Your declaration is attempting to use a double as the input. You have to use a DataSeries, so you should first create a DataSeries using VOLRaw. Then you can run any indicator on the DataSeries.
