I trade 1 to 5 lots. It all depends on how strong my signal is.
I am scalper and I trade the Asian and part of the European session.
Since, we did not erupt in a troll thread. Based on what you have said (so far),I would like to recommend Tradovate for these reasons:
1) A better platform. Do a demo! The company was founded by the same guy who built OEC with the highly successful and long lived OEC Trader. That was a well built platform. He definitely knows what short term futures traders need. Make sure you can run your tools/methods.
Incidentally, Tradovate has provided add-on functionality for the most popular tools like Jigsaw, Bookmap and OFA for additional costs. I am not saying you can make money with these tools. But again, the most modern tools with the most modern technology...
2) Costs. Based on your average lot size, I highly recommend you make a spreadsheet out of your average daily volume. People have no business scalping if they can't make these calculations. The $100 a month is an easy hurdle for 3 round turn lots a day in broker commissions. And, that is not including free data for 1 CME exchange. See if they can provide your favorite exchange for free.
3) Margins. Let's not even discuss this. You can google this info.
4) Mobility and ease of access.
Best of Luck. Don't ask this question on ET again as you can start a war.
