Hey Perannal,Which products/platforms were you using with FP Markets, I mainly trade currencies with their Raw spreads (ECN) MT4 account and haven't had any issues with their Trading conditions, it has been stable even when the markets have been volatile recently.
Regarding the payments, if you use methods like credit card, pay-pal, Neteller etc. It should reflect in real-time. Bank wire depending on the country you deposit from will take upto 2-3 working days I believe.
