End Of Day Only

Key End Of Day Only in ExCfgLvFdMS refers to a boolean that controls whether the retrieved latest feeds refer to the latest End Of Day or the intraday quotes.
TRUE means that only the latest available End Of Day quotes are displayed.
FALSE means that the latest available intraday quotes are displayed.
The default is TRUE because Marketstack does not support intraday feeds on most international stocks.
Quite obviously, if the setting here is TRUE, there is no need to keep refreshing the displayed live feeds.
