Yesterday, I brought my chart up to date from IB for the symbol FDAX 200606. I closed the chart and immediately re-opened it and the chart appeared without any delay. The market did not trade yesterday. This morning, before the market opened, I reopened my workspace and its been over 30 minutes and no chart.

Data Cache Reload Problem
I would like to know this (differenece between Online and OnDemand) the descriptions sound quite similar.
I guess Online does data feed first and if it misses any data there it will look in the chache?
I guess Ondemand does cache first and if it can not find data there it gets it online?
I presume both remain connected to the feed and fill in the cache with new real time data?
Could you spell out exactly what happens with each mode for us slow guys
Thanks.

In On-Demand mode MultiCharts, when a chart is created, looks up the data already stored for the symbol, checks for any gaps in this data up to the current date/time, downloads data to fill gaps and then connects to realtime.
In Online mode the stored data is used as is, without checking for gaps so Multicharts can connect to realtime datafeed at once.
