Code for tick chart is not compiling, do we need to import some libraries?

ITickBarFeed cannot be resolved to a type

TickBarSize cannot be resolved to a type

A sample trading code would help.

Please make sure that the following imports are used

import com.dukascopy.api.bar.ITickBar;
import com.dukascopy.api.listener.ITickBarFeedListener;

If it does not help, please provide strategy example that is not compiling.

I'm using Jforex Live account, Dukascopy ver 2.12.22 which has JForex API ver 2.6.33. So trying to import new version of API from external location. Here is the code:

package jforex.strategies;
import java.util.*;
import com.dukascopy.api.*;
import com.dukascopy.api.Library;
@RequiresFullAccess
@Library("C:\JForex-API-2.6.50.jar;C:\JForex-API-2.6.50-sources.jar");

and the errors while compiling:

The import com.dukascopy.api.listener cannot be resolved
The import com.dukascopy.api.bar cannot be resolved
Invalid escape sequence (valid ones are  \b  \t  \n  \f  \r  \"  \'  \\ )

JForex client does not support running strategies that use newer API versions.
In order to call run strategies with new API, standalone JForex API should be used: https://www.dukascopy.com/wiki/#Standalone_JForex_API
