I am using Metastock using QuoteCenter live data, trading both SIMSCI and DAX, with Phillip securities. I start to dislike Metastock and Phillip. Metastock was great 10 years ago but not anymore. It didn't improve with new technology. Still stuck with very old technology, user interface. Same for Phillip. It was great 10 years ago then they first started phone trading, internet trading. Not again didn't improve with new technology.
TMI is about $100 per month, though you need to pay 1 year upfront. Rate is low compare without TMI. If you are going to trade with Phillip, Ongfirst, it is better to sign up TMI. $100 per month is worth about 4 round turns.
I like IG markets the best. Good reports for me to anlyse/review my trading. Very details about every move I made : how I adjust my limit, my stop loss, open position, close position. Charting software very intuitive to use, trade on chart, easy to create alert, even auto-trade base on alert (if you want). But it is not a open exchange. They are the market maker.
I just open tradestation. The rate for DAX, S&P is as good as TMI rate. No Asia market though, just US and Europe. Will provide some feedback on tradestation after i spend some times on it. One thing I know is it is expensive to transfer fund in and transfer fund out.
Will definitely explore IB for other shortcoming of tradestation, such as Asia market, cheap to transfer fund in/out.
I am currently focus on futures, but will explore forex later.
