++
++These things are pretty much invariant; they don't depend on the
++data provider. They are basic facts about a futures contract, like
++trading hours, point values, option strike increments, minimum
++allowable movement, and so on. There is no reason to have to input
++all that manually. If I tell the software that the root ticker
++symbol is GC, the software should immediately configure itself for
++Comex Gold, using $100/basis point.
++
++I say again, this is a pretty basic requirement for futures traders.
I just remember, then why was i sitting for hours to key in basic facts in
TS2000i here in germany... hours and hours.... i swear.

++
++That's false. The names, and especially the ticker symbols, are
++pretty well standardized, with just a few minor exceptions like JO
++vs OJ for Orange Juice, or GO vs GC for gold.
++
++>This will be added once we have our own data. Also margin
++>is changing all the time, so is point value from time to time.
++
++Margin requirements do change, but there still should be a database
++of them for the user to change.
++
++Point values rarely EVER change. 100 ounces of gold will always
++have the same point value, forever. The only time it may change
++is if the contract size changes, for example when Lumber went from
++160,000 to 80,000 board-feet. That is a rare occurrence. Again,
++there's no reason not to maintain a database of these facts --
++ESPECIALLY for anybody wanting to analyze a portfolio of contracts.
++
++>Most people want to use there data provider, so we would like
++to allow them
++>to use any data vendor. Of course that means additional work.
++
++The only differences are data formats, like how dates are
++represented, whether the data are tab or comma delimited, etc. Not
++many differences. I wrote an import routine to support 5 different
++data sources once. It's not hard!
++
++>++ This is a critical feature, *especially* when testing
++>++ a portfolio of futures, all having different point values and margin
++>++ requirements.
++>
++>You can adjust that on your own... very easy.
++
++Does the software remember that ES is $50 and SP is $200 and O is $25
++(or whatever)? In other words: is there a database? Or is it something
++the user has to set manually for every situation?
++
++>I think most of your concerns are solved already. I see WLD2
++as a mixture of
++>Trading Recipies and Trade Station 2000i. I must admit WLD2 is
++very complex
++>and has so many feature that even out hardcore users dont know
++them all. But
++>surely not all requests are included yet.
++
++That's nice to know. Now if only you could fix the language to be more
++EL-like and less Pascal-like, without the need for bookkeeping....
++
++While I have your attention, here's one feature I would really
++like to see -- let me know if you've done it: I want to be able
++to optimize custom results. TS2000 lets you optimize net profit,
++win/loss ratio, and a bunch of other canned analysis results. But
++suppose I had my own version of the Sharpe Ratio, or my own idea
++of how to measure system performance, and I could express it in a
++function? THAT's what I'd want to optimize, not what the software
++already provides. I'd like have available an empty function whose
++result the optimizer checks, and that function I'd fill in with my
++own code, using inputs like equity, number of trades so far, length
++of time in trade, and so on.
