thank you that was a big help I think I am one step closer but still, I can’t find the link between the CFD orders type that we use and the liquidity that banks provide i think i should read a lot more then ask my question to neither can better provide my structure of questions and nor understand your answers
I would like to clarify that it is not in anyone’s hands to move the forex prices, be it banks or the market makers. It is just that if you are using an unregulated broker, it can widen the spreads but that too in the rarest cases.
Also regulated brokers can and do adjust spreads, it is not a question of regulation. The issue is their motivation for adjusting spreads. Any broker will widen speeds during thin markets or in anticipation of greater volatility during certain events and will often warn their clients of this possibility. But unscrupulous brokers may do so excessively just to hit nearby stops.
In general conditions no single institution can move the forex market but there are rare occasions where sudden and excessive moves can be ignited, triggering automated systems etc which end up as self-fulfilling plunges commonly called black swan moves. Smaller ripples can also be caused in very thin trading sessions.
