ENDED MY LOSING TRADES

Hello I'm Samuel, a newbie to the forex market. my first broker is octaFx, but I noticed something conny about the broker today. I had 4 ongoing trades and when I clicked on my trades, I saw only one, at first I thought it was bad network, so I didn't really bother much not until I clicked on the next icon and saw that my trades have been ended? my newly funded $5k account is currently $3k because of the trades losses. I'm pretty sure this was done by the broker I'm gonna quit octaFx.
