I was watching one of Jim's presentation about how he was using kevlar in his IRA account and I thought ... hmmm, why not? However, when I checked, my IRA has pretty tight restrictions, I can take it to only 1 broker and that is Charles Schwab and they charge 9 + 0.75. I can probably negotiate with them, but lets assume that's what it is. Now I know different strategies have different risk rewards and they take higher precedence in decision making as compared to commissions. However, if I wanted to evaluate a strategy only from the perspective of commissions, then it would imply that a strategy with a lot of trades and a strategy with lot of small trades will fare worse. For example, I buy a butterfly as a single trade vs 2 leg-trade, cost is different. Then I add a teenie, its 10 bucks gone just to add it, and 10 bucks to sell it eventually. However, in a nested condor for example, I take a full leg (5-10 contracts) and either exit it full or roll it fully (not always) and I never have to wonder if my cost would have been just 1.25 vs 9.75. I wonder if someone has analyzed the commission impact on our strategies and analyzed this new greek that I am calling "Fomma" = Fees for running 1 cycle of strategy with typical number of orders for let us say a 5K portfolio, 25K portfolio and a 100K portfolio.
