E signal links to TWS, and others do also.
You can set up TWS to make it easier and faster. Just set up the columns you need. The help section tells you how.
In addition, you can set up keyboard to set enter brackets, buys, sells, cancells, transmits, etc. Makes for very fast entry.
In addition to using the sell function to short, if you wish to sell 100 shares, and short 100 at the same time to reverse your play,
just sell 200. In most cases you should then be out of your long
and into your short for the cost of 1 trade.
To cover your short, just use the buy function.
