Thanks Hunter for the suggestion, I have already looked at BigMikeTrading

Hi Bertrand,

The method MIN(TEMA, 252)[0] is very probably that I am looking for instead of Math.Min(..) but I cannot compile the code

double TEMA=((((Close[0]-EMA(13)[0])*0.6)+((Close[0]-EMA(23)[0])*0.3)+((Close[0]-EMA(55)[0])*0.1)));
double CEMA=(((100-0)/(MAX(TEMA,252)[0]-(MIN(TEMA,252)[0])))*(TEMA-MIN(TEMA,252)[0]));

Do you have any suggestion where the mistake is ? The program error indicate that I cannot convert from Double to DataSeries

Loukas, you have set TEMA as a double variable and then try to use it in the MAX and MIN functions, which require a data series. Please see this reference sample for a demonstration of how to use data series to store an intermediate calculation to use in methods that expect a data series.

Thanks Austin, Could you give me any suggestion where is the mistake at the second dataseries

TEMA.Set(((Close[0]-EMA(13)[0])*0.6)+((Close[0]-EMA(23)[0])*0.3)+((Close[0]-EMA(55)[0])*0.1));
CEMA.Set(((100-0)/((MAX(TEMA,252)[0])-(MIN(TEMA,252)[0])))*(TEMA-(MIN(TEMA,252)[0])));

Plot0.Set(CEMA[0]);

The erro explanation is that I cannot apply "-" to dataseries and double.
Shall I make other 2 dataseries for MAX and MIN ?

Loukas, the error is here: *(TEMA-(MIN.

The TEMA you're referencing there is still a data series, and you're trying to multiply the data series by a value, which won't work.

You can do this though:

CEMA.Set(((100-0)/((MAX(TEMA,252)[0])-(MIN(TEMA,252)[0])))*(TEMA[0]-(MIN(TEMA,252)[0])));

Note the [0] after the TEMA, which pulls the most recent value from TEMA, which is also a double value.

Great, Thanks Austin
