If a try docompile EA, Jforex send message - Type mismatch: cannot convert from double to OfferSide

How are fixed this problem?

Thanks for help!

At line 12 you assign a double value to an OfferSide variable. Consider using some IDE (e.g. Eclipse) to assist you on such errors:

I now there error in my code.

How convert double to OfferSide, or why realize price_typical function?

You don't need to calculate the typical price, the indicator does it for you. That is just make the indicator call in the following way:

iCCI_Signal = indicators.cci(instrument, Period.FIFTEEN_MINS,  IIndicators.AppliedPrice.TYPICAL_PRICE, period, 1);

In https://www.dukascopy.com/client/javadoc ... ,%20int%29 It is impossible to use AppliedPrice.* for CCI

double cci(Instrument instrument, Period period, OfferSide side, int timePeriod, int shift)

AppliedPrice.* use for indicator ma - https://www.dukascopy.com/client/javadoc ... ,%20int%29 , not for CCI

If i try decompile iCCI_Signal = indicators.cci(instrument, Period.FIFTEEN_MINS, IIndicators.AppliedPrice.TYPICAL_PRICE, period, 1);

send message

16:11:38 The method cci(Instrument, Period, OfferSide, int, int) in the type IIndicators is not applicable for the arguments (Instrument, Period, IIndicators.AppliedPrice, int, int)

Pardon, the right function call is:

iCCI_Signal = indicators.cci(instrument, Period.FIFTEEN_MINS,  OfferSide.BID, period, 1);

We reiterate that the typical price calculation gets carried out in the indicator itself so you don't need to pass this value to it.
