I been trading DMA CFDs on fpmarkets. Have stuck to blue chips mainly due to liquidity as you mention. Agree CFDs are better short term, playing with small capital at moment, for example 2% trade loss is $40!!!!, so makes having wide enough stops for 3-5 day trades quite difficult.
Finding most successes on scalping on blue chip swings, trouble is its a bit too labour intensive on intra to 2 day trades.
