On the whole the deal4free prices follow the US very closely, but they will appear wildly out if the underlying size in the market is thin (this happens a lot with ICOS). If you look at a Level2 screen next to deal4free you can usually see why their prices are the way they are. That doesn't make it any easier when they requote you though, or just fill you at a stupid price without even bothering to requote!
However, a bigger issue using deal4free to trade US, is the very small range of stocks available through them.
I can easily see why there may be a big difference in Spread on a stock that also has a large spread. It would be interesting to see how the D4F spread varies against a level II spreadon the same stock.
Nice graph, but I'm afraid you've made it look a lot better than it really is!
The MT graph has a range from 43.1 to 44.25 , the D4F one goes from 41.95 to 44.25! You've overlayed them withou taking that into account, I'm afraid, if you adjusted the scales the MT data wouldn't even come halfway down the D4F graph!
I had a short on Ariva once with D4Free. The charts were all over the place. I think they have problems with their charting software. It looked like I should have been stopped out several times but I wasn't so they obviously don't go by their own charts.
If you try buying on those big dips, they won't let you. It is a pain if you are trying to close a trade.
please can someone compare the d4f prices with IB , probably we need to leave the charts aside, im not sure abou American stocks but as far as im concerned d4f cfd prices for ftse100 are the in the line with the market spread.
