The problem with FX and Indices is that most traders are trading on a tiny movements all day long "percentage wise" , a 4 points move in the ES is just around 0.22% and a 20 points move in the Euro = 0.15% , lets face it thats a really small move , its like trading MSFT with 5-8 cents SL ! Thats noise , even if it isnt random thats "unpredictable" , can you imagine how many traders and price engines and algos are competing in this area ?
Not to mention the leverage offered on these markets , plus the hype ... etc its a formula for disaster for most traders , not to forget that the spread and costs effect here is huge cuz its a big portion of the targeted move , ie: If you trade the ES with a 4 points SL your costs is around 0.3/4 = 7.5% , and if you trade the Euro with a 20 pip SL your costs are around = 2/20 = 10% , now if the ES moved 4 points in your favor you are up 3.7 and if it moved 4 points against you you are down 4.3 , lol , and if the Euro moved 20 points in your favor you are up 18 pips and if it moved 20 pips against you you are down 22 pips , i don't see how you are going to make money that way .
Excellent post, sounds like someone who has done his homework. Mike Harris in his blog shows how 2 pips of commission and slippage in EOD trading makes forex a 100% negative sum game unless one possesses an extraordinary edge. He also shows that when only1 pip is added for commission and slippage in intraday trading it becomes a 100% negative sum game, unless one possesses some structural edge that is unique.
