Quote from I$land:
I would like to be able to scan a watchlist of 300-400 stocks.

Your watchlist on daily charts can be as large as you want it to be, but you will need to cut that down each day to 700 based on some criteria in order to scan intraday timeframes.
For example, you might have 7000 symbols loaded in your database which are updated daily after market close. You will then scan that list with limiting criteria for your watch list the next day, which you can then track in real time with charts and quote pages. Regarding quote pages, think of an excel-type spreadsheet that you can program with indicators, and sort automatically in real time, with visual and sound alerts, etc.
Let's say you want to track all 700 stocks on a 2 minute timeframe, sorting them based on the close of the last bar in relation to its close 2 bars ago. Or, you want to sort based on a technical indicator, or pivot point, or relation to previous daily data, or relation to market averages, or whatever. Just program a quote page column, then sort the page and ask it to update every few seconds. Might also want to color code the column based on levels of the indicator, and ask for a sound alert when levels are reached. Also might want to have it automatically open a chart that is set with reference lines and buttons you can press to initiate a trade. Etc. etc.
As with any software, there is a learning curve, but the language is very easy and the effort is well worth it.
