I have been on a daily contact with WHC in getting their English version of the website. It should be up and running shortly.
They have market execution on their order entry similar to US based futures brokers. As has already mentioned, WHC has 0 spread on futures but commission is charged. Again, just like the way it is done by regular futures brokers. I have compared their price ticks and I must say that they are right on the penny. Their execution is fast and I have not experienced any requote yet (remember, it's at market price) nor a disconnection. They also maintain servers both in Russia and in California, USA. English speaking traders support team is now being put together to serve you.
They have full line of forex currency pairs with very tight spreads, i.e. GBPUSD 3, GBPJPY 6, etc..
Anyhow, here is the direct MT4 demo download link and you can give it try:

I now have my chartshare in our H2 trading room on WHC platform.
ENJOY!
