Indicators & custom dataseries

[cunparis]

I'm missing something when it comes to using custom dataseries.

The indicators take a data series. So if I make my own, say based on the close, then I can pass that to the indicator and I compare the result to the result without passing my data series. I get the same thing so I know that it's working.

My question is some indicators use more than just the close price. If I pass them a BarsArray object, how do they get the open, high, low, & volume data?

I found this problem when using force index. it uses volume. but if I'm using my own custom dataseries I have no way to give the volume information to force index. All I can pass in is a dataseries of the close.

Hi cunparis, not sure I follow your post - for exmaple OHLC and Volume are already dataseries by default, so you could pass them in directly as done in the code for the Force Index you refer to. If you call this indicator from a strategy, there's no need to supply a dataseries for the input price or volume then.

Let's say I want to create my own data series for OHLC V. Just for a simple example, let's say I want it to be 1 bar behind. This doesn't make sense but it's a simple example. So in OnBarUpdate I have:

closeSeries.Set(Close[1]);
openSeries.Set(Open[1]);
...
volumeSeries.Set(VOL()[0]);

but how can I pass this OHLCV series to an indicator? Does the ForceIndex indicator take a data series that has close & volume? or does it take two data series one for close & one for volume?

You need to pass two dataseries then, one for your volume and for the close prices. The ForceIndex version I have does not offer to pass in dataseries inputs directly so you would need to modify the code to open this up.

If you want to pass one dataseries to another indicator, you would need to expose them first to make them accessible. For this please see this reference sample - http://www.ninjatrader-support2.com/...ead.php?t=4991

Thank you for the precision. I couldn't figure out how to use force index with my custom dataseries. Now I know it's just because the indicator hasn't been programmed to accept them.

Thanks
