I'm going to move the brokers related posts to Brokers and commissions.
Let me repeat what mentioned countless number of times: ticket fee will have devastating impact on your account, especially for small accounts.
Lets do a quick math. We do at least 10 trades per month in our model portfolio. Since many of them are double calendars, and some straddles with adjustments, we can assume 40 trades per month. That's $400, or $5,000 per year, thrown directly to garbage. For 10k portfolio, that's 4% per month or 48% per year.
If you switch to IB and save that money, you can spend a small portion of those savings and buy options software like ONE that leaves TOS far back.
