Hi,

I have been trading on CEX.IO for about two months without any major issues, till the last couple of weeks.

In the last couple of weeks, it became too laggy and buggy. It gives frequent "network call" errors when you try to place an order or cancel it, which results in losing opportunities or even money since you can't place or cancel orders on a timely manner. Even worse than that, their system became too laggy that sometimes, even after you cancel an order, (after 10-15 minutes), the system automatically places one of your previously canceled orders, without you even knowing it.

Yesterday, which was also a laggy day, I closed my last trade and logged off from CEX.IO. Today, when I logged in, I noticed that a buy order had been placed and executed after closing my last trade, which caused me a considerable loss. The same thing happened 3 or 4 times in the last two weeks, but luckily, I was online to cancel the unintended buy orders timely. This time, I was not online and I lost money, due to the lag on CEX.IO server.

If you don't want to lose money, stay away from CEX.IO.
