We all know cases when brokers trying to hit your SL by widening the spread like a big gate in order to get your money. This kind of manipulation is illegal BUT Forex is an “over the counter” business and hard to control by authorities. 

That is why the artificial intelligence of the neural network will hide the SL to prevent such manipulation and even trying to confuse your broker by using flexible SL and TP targets. Meaning SL and TP will move permanently.
