no uk acho que ha um seguro para o caso do broker fugir com o dinheiro (creio que sao 80k). nesse aspecto eh melhor. mas nao encontrei la nenhum broker com bons precos e transparencia. se encontrarem um partilhem, nesse caso eu consideraria mudar.
o ic markets nao eh DMA, usa o modelo "agency broker", apesar de tudo muito melhor do que o modelo de "market maker"
The Agency Broker model closely resembles the DMA model in that orders are hedged directly via the underlying physical market. Under this model, however, participants will not see their limit orders on the exchange as such orders are held by the provider and passed through only when they become marketable.
