After 3 month future trading, I found that future is not as predictable as stock price, because there are constant news update, where in stocks, there are sometimes no news between 10Q filings. And it is pretty easy to predict what management will do based on their past actions. However, there is no Interest Free Margin in stocks. I already borrow too much and paying too much interests. I get some info from CMC market, but it seems they also charge interest if I trade their CFD. Is there a interest free margin in stocks? Any stock future, not index future? If there is a detailed study/comparison on CFD, let me know. Thanks.
