Anyone using all data everywhere ADE for tradestation

Does user have to put up a chart and apply the storing ADE indicator in order to store the data?

Is there a function directly retrieve the data from the existing tradestation or multicharts data base and use the data directly on other charts rather have to put up a chart to store the data first?

Using fetch ibm or msft symbol

ibm close = fetch(sym, "ibm", close)

Does ADE allow the above?

I've used ADE in the past and it does allow you to use data from other timeframes as well as for symbols. From the user guide:

Another powerful use for ADE is to look at data for other symbols. You can use ADE to store data (OHLC, volume, indicators, etc) for an entire portfolio of symbols, and then you can access the data for any symbol from any other symbol. This makes it possible to perform analyses that depend on the relationships between different symbols in your portfolio.

You can find all you need to know with the TS ADE Guide found here (Word Document - publicly available).
