Quote from Jason Rogers:
The micro spread is lower because our expenses on micro are tightly controlled.
First, there's no phone or chat support. All of the support is online through the interactive support forum and by email. Second, there are no customization options for accounts. All accounts are individual accounts. All accounts are funded by credit card or debit card. All accounts are self-traded, no referring brokers. This helps us keep everything as automated as possible, and thereby keep costs lower in return. It's a good option if you want to start with a very small balance to test and can manage with the self-help options.
The standard 10k account spread is about a pip wider on average because you're paying for full support and more account options.
This is our goal with the active trader platform. The commission we charge is based on the amount of volume you are doing each month. The more volume you trade, the lower the commission we can offer, and scalpers are certainly welcome.
Active trader spreads are very competitive right now on eur/usd, usd/jpy, usd/chf and aud/usd. GBP spreads are not as sticky as we would like, but we are working on customized deals with the banks. What you can do is try the active trader demo to see the spreads, and give me feedback on what you think about the platform.
