How can Agimat EA use a SL and a hedge at the same time?

The neural network takes care of this by using non-static SL. The SL is not fixed at all when hedging but will become static to have the trade cut out if necessary. This is a very complicated process since the neural network works artificially & independently...

Does Agimat EA work without neural network?

No. The Agimat EA needs the neural network synch in order to function. Keep in mind the EA is just a client software on your site and requires our server technology to work properly.
