This my friend is probably more true than not.:
The delay between bridge and liquidity could be high enough to induce slippage or neglected fills. So in terms it is.
To tell the truth, there arent many true ecns on the market. And the ones that are imitation, generally seem to be the most popular (because they offer the best conditions, which dont truely exist within an ECN). But the fact remains, if a trader is shedding, they will forever blame their broker.
ECN isn't for the faint hearted. I really don't suggest anyone go there till they truely understand ecn conditions and the outcomes of those conditions.
