Is trailing option working?

I am playing around with trailing stop loss

The 1st image is where I set it up and by my understanding with will stay 0.8 behind. When the market is not in my favour the stop should remain static?

But as you can see on this image the stop is actually decreasing?

Something I am missing?

Thanks in advance

What platform is this?

As long as you are looking at the screen to adjust the setting, the trailing function is not yet active.
Simply try out these kinds of tests in the demo environment.

Trailing is only available in CFD.
