I believe FXCM offers a spread of 20 points on the Italian index. As a % of daily ATR that equates to around 3% - in comparison the DAX comes in at around 0.5% on that measure. This is something I also try to watch really closely. I want to know how much my transaction costs are and keep this as low as possible.
I often find it useful to draw a casino analogy. Fun/excitement factors aside, I would you rather play blackjack (0.5% house edge) than single-zero roulette (2.7% house edge) because the "transaction costs" are a lot lower.
Hey but if it works for you great! Good luck with it 🙂
