Hi Gianfrancotanzi,
The best advice we can give is to check your EA for the conditions that make the trailing stop to move. Check also the ‘Journal’ tab which may be giving you errors when the order details are being changed. In this case, it is often the specified price that could be causing the problem (i.e. it isn’t being “normalised” correctly). If you are getting errors, it will specify an error number which you can Google to find out more.
Hope this helps.
