::* Select type of connection: '''demo''' / '''real'''.<br>According to your type of connection URL is set up automatically.
::* Enter '''Login''' and '''Password'''.
* '''Cache downloaded quote files''' - this option enables storing the downloaded data on your hard drive. When this feature is enabled - upon reloading data on a chart it will be loaded from the cached files, instead of the data provider historical data servers.
* '''Use heartbeats for connection loss detection''' - heartbeats are utilized for detecting connection loss and reconnecting. If heartbeats are not being received from the server - reconnect is done.
* '''Build trade ticks from ask ticks and bid ticks''' - when this option is enabled, quote field "Trade" includes both Bid and Ask prices which makes the Volume Profile feature usable for Forex symbols. Trade field records a new tick even if only the Ask price/volume has changed and does not wait for the Bid to change either price or volume. When the option is disabled - Quote Field "Trade" plots "Bid" data.
