Actually, the legal meaning of the clause is the same, it has not been changed. This will be a problem for you after contacting CYSEC because the terms have been accepted by them. Moreover, you have agreed to the terms! I believe that CYSEC cannot help very much in this case but make sure you use their middleman services.
In addition to that, most brokers offering fixed spreads have similar clauses in their terms as it is harder to manage the risk while using ECN-structured platform with fixed spreads.
As per claims for using additional MT4 bridges, yes, it is possible, many of the brokers have used some additional plugins during their startup period.
Back to the case...Did they correct the result of the trade that was considered to be executed during a news or a gap?
