Protect clients ?
Why you don't have this "protection" when I trade 5 million in futures or stocks ?
Plenty of liquidity ?
Forex is the biggest market in terms of liquidity and EXACTLY in that market you have limits , sounds logical..
We both know the real reason, no ? :)
good example you bring up !
I think, like in most areas of trading, it depends from the traders specific trades,one should go over his past trades to adjust stop settings
