problem clearing historical data

[Marxx]

I have cleared (Clear button in Data Center) all historical data for all pairs (each pair separately) and imported fresh data from an .hst file.

In History Mode the data shows correctly, however in Testing Mode the test starts at a period for which I don't actually have data imported and it doesn't show the period that should have data.

It seems that the historical data has not cleared correctly?

What should I do?

Thanks.

Please make sure that you generated ticks correctly (http://www.forextester.com/ticks.html).
Also make sure that you are starting new test from valid date.
