Quote from taboni:
Lon both ECNs I am familiar with (Hotspot and IB) won't execute a stop until the market goes bid or offered at the target price, so it really doesn't matter if the spread widens during the Asian market.
I use Hotspot, Lava and Currenex.
I don't quite undertsand your point. Say you are short of cable and leave a stop at 1.7600. I appreciate you saying that Hotspot only fill you if it goes 1.7600 bid. However if the spread is wide (as it quite often is when not in New York and London time)you could get a shocking fill.
For that reason I leave stops with a trusted non ECN type counterparty.
