There are 3 types of CFD's on offer:
- Market Market CFD's
- Direct Market Access CFD's
- Exchange CFD's
Providers like CMC markets and GFT are market makers, whilst IG Markets, Marketech, City Index, First Prudential and MF Global offer DMA and exchange CFD's.
The main difference between market maker and DMA is the latter is placed on the market, which means it enters at market price; closes out at market price, and you can access the open and closing auctions on the ASX. The difference between DMA and Exchange CFD's is the latter have a cheaper open interest charge of 1.5% above the RBA cash rate as the provider does not have to take a direct position in the market for the client (DMA) or themselves (market maker). The average open interest charge premium for MM and DMA is around 2.5-3%. The other difference is that Exchange CFD's need to be closed out at the end of each trading day.
Apart from equities, CFD's can also cover FX, sectors and indices.
Nearly all providers will charge a platform fee and/or market data fees per month, but some will take on the cost for overseas markets (CMC markets) or provide delayed market data for free (IG Markets). These costs may be negated if the broker allows phone trades like FP markets and MF Global.
The variation margin that is incurred when a stock falls is broken into 2 parts:
- Percentage based margin: percentage * price * no of cfd's
- The loss margin: drop in price * no of cfd's
If you purchased $10000 worth of BHP @ 5% margin @ $30, than it drops by 5% to $28.50........your variation margin would be $500 - (5% * $28.50 * 333 CFD's) - ($1.5 * 333 CFD's) = $473.
