Hello,

When backtesting using the SDK, the program does not go past the following messages:

We use the following Java libraries:

    // dukascopy API for trading
    compile(group: 'com.dukascopy.dds2', name: 'DDS2-jClient-JForex', version: '3.0.16') {
        exclude(module: 'slf4j-jdk14')
    }
    compile group: 'com.dukascopy.api', name: 'JForex-API', version: '2.13.26', classifier: 'sources'

We are on this problem.

TesterClient actually does return from "Getting prices before start time" after significant amount of time.
During that time it creates a huge but empty directory structure in your JForex cache.
Then it runs your strategy but feeds no data into it.

Please, let us know as soon as this problem has been fixed.

Please update to version 3.1.0 (JForex 3) or 2.45.67 (JForex).
