I started trading with FP Markets, and it has been four months trading with them. So far, I did not come across any issues during withdrawals or deposits. And the spreads have been consistently stable, particularly with the EURUSD pair, even when the market is highly volatile.
From my trading experience, I can say FP Markets is a legit broker. They are one of the oldest brokers, active since 2005, with regulations from ASIC and CYSEC.
FP Markets is an safer broker to use. I've been trading with it for six months and the trading conditions are robust with quick responding customer service team.
I have been trading with FP Markets for over 2 years and so far no major issues have occurred. The spreads are stable as promised with a commission cost of $6 per round lot, which is lower than most ECN brokers.
From my personal experience with them for over a year, I can say they are reliable because I did not come across any issues regarding spreads and during withdrawals or deposits.
