I'm currently trading with FP Markets. I've been trading with them for three months so far; the experience has been good, and no issues like spreads widening or servers freezing.
It's very important to have a good broker on board with you for more profit in the forex market. up till now, I have excellent services offered by LMFX broker.
What trading platform are you using? I have seen many traders complain of MT4 freezing these days, I have personally not faced such issue though.
Now I have been trading with FXOpen, I have registered on this broker already more than ten years ago, but in few years I am vacuum in forex and then come back again, still trade with this broker because it's regulated in ASIC, FCA, and CySec. I think it good for the future.
