Since MultiCharts 8.7 beta 1 it is possible to cache historical data downloaded from LMAX to speed up data backfilling. To enable caching downloaded data: # Open QuoteManager,# Click * '''ToolsCache downloaded quote files''' in main menu- 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.# Select * '''Data SourcesUse heartbeats for connection loss detection''',# Highlight LMAX,- heartbeats are utilized for detecting connection loss and reconnecting. If heartbeats are not being received from the server - reconnect is done.# Click * '''SettingsBuild trade ticks from ask ticks and bid ticks'''- when this option is enabled,# Check ''Cache downloaded quote files'',# Click OK 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 apply change either price or volume. When the settingsoption is disabled - Quote Field "Trade" plots "Bid" data.
