In regards to trade zero I am a relatively new trader so I'm unsure if this is normal but the platform seems to refresh at random intervals which appear to happen every 5 10 mins leaving my charts, level 2 and time and sales blank for anything from 2 to 30 seconds. This alone would be annoying but my Level 2/ DOM reverts back to market orders which when in the middle of entering or exiting a trade adds a few more seconds to something that is already a serious inconvenience. Any replies that could clarify IF this is Normal and WHY this happens would be greatly appreciated
