I have had a look at the index DAX and FTSE which I am usually trading, the spread is 0.90 point, so that is actually ok. I will have a look at the US index when they open in the US. But the platform, I don't know, it will for sure take some time to get used to.
I have found the execution time to be rather slow using the demo account, hard to tell about the slippage. If one always get the price you have clicked on, it doesn't matter that much, if it takes some time for the platform to update the trade.
Yes that is a good thing, but the he platform and execution time though is giving me doubts. The spread on the Nasdaq is ok, 0.58 points , 3 points on the the Dow, not great but acceptable.
