Can anyone recommend a good platform for order entry, having some kind of popup window (probably a DOM is what most of them would have) that lets met enter a trade and watch the P/L

requirements
- some kind of floating entry window (e.g. DOM)... not interested in a big application terminal window for order entry

- ability to prevent connection problems or hitting "flatten/close" buttons multiple times from causing you to open a position in the other direction

also nice:

- ability to change P/L to ticks or points, depending what I want to look at. A lot of them seem to lack this fundamental capability.

- ability to create the dom or order entry window without needing a chart open

- good historical reporting including filtering of results and charts that display profit each day
