Hi, you have told about problems with mistakes of fills with 3 or more % from the last price. I have had some other problems with island(routing via IB): If i want to buy e.g. the ask, sometimes i can`t get a fill, if there`s a bigger deviation from the last price e.g. of 5 %. It`s seem`s to be blogged? Is it possible? Is there any rule , i don`t know?
