The broker is quite safe, you know. The trading conditions are rather good. The variable spreads are not high though the commission fees increase them materially. But when I was trading with currency pair EUR/USD, the spread was equal to 2 pips and they did not impose any commissions and mark-ups. So, there is a max.level.
Trading with Colmex is unexpectedly easy and stable as for a relatively unknown broker. There are different plans with different trading conditions with various amounts to deposit and trading platforms to use. Here you can count on relatively low spreads but at the same time you have to pay quite high commission fees. Oops! This is not good, but really the spreads are pleasant here, so, it is simpler to make successful deals and gain profits. I have been thinking a lot whether I should choose commission-free accounts but with high spreads or Colmex and decided in favor of this broker.
I'm trading with colmex since 2013 and I'm not planning to replace them soon. It can be a little slow going, especially with market changes, but I'm happy with the overall service at Colmex and I'm going to keep an eye on the real time quotes displayed as they have been helping a lot.
Trading with colmex for over 6 months. I find that the withdrawal commissions higher than I'm used to, but from the other hand I'm willing to pay it because I'm not worried with this company. I trust them.
