Convertinb Double to DataSeries

I'm trying to use some indicators used for price, such as the CurrentOHL, on an indicator. Unfortunately OHL will not do indicators because it's designed for a dataseries.

I'm wondering if it's possible to convert a normal double indicator into a dataseries, and feed it into OHL? I looked at the source for the CurrentOHL, and it clearly is designed for a dataseries only, and not a double value.

Not sure I am clearly understanding what you asking, but all indicators are called the same, you can do either,

Output[0] = InputIndicator(parameters)[0];
or
double Output = InputIndicator(parameters)[0];

the only difference is if you want to evaluate prior bars on Output then you have to create a dataseries, for example you can do,

Output[0] = InputIndicator(parameters)[0];
Offset2Bars[0] = Output[2];

but you can't do,

double Output = InputIndicator(parameters)[0];
Offset2Bars[0] = Output[2];

If you aren't sure how to call another indicator then you can open the strategy wizard and use the indicator in a formula then view the code to see which parameters are included and the order they are used.

So InputIndicator(parameters) is where the indicator would go? I'll give this a shot, it looks promising.

What I'm trying to do is convert an indicator to a dataseries, so the CurrentDayOHL will tell me the Open and the Close of an indicator.

I understand better, I don't have NT installed anymore so I couldn't try it, but I don't think you have to create a new dataseries, simply replace Open[0], High[0] and Low[0] with your indicator call and that should work.
