I had many lags one day when my internet connection was very very low, so when i made any buy or sell order the button was clicked twice which made me many loss which i didn't wanted, the same was with the withdrawal, every operation was like i was clicking 2 times the button, so i think check your internet connection stability.
internet speed is 40 megs noob and pc is a beast dont assume the company is right you idiot. freezing of orderbooks and inability to execute trades is what we are talking about here.
You called me an idiot?? or i didn't read it right, I'm telling you from my experience that i had in the very near past and i assume that it was because of my unstable internet connection and the site was acting slow on my actions(clicks).
