The day before yesterday, I had $2500 in my account, couldn't withdraw. So I decided to set up a buy order of 2000 BTC at 5.17, and put a stop order at 4.99, and then went to sleep.
After waking up the next day, I saw it was sold not at 4.99, but 4.44, my balance was less than $1000, a lose of nearly $2000!
Yesterday, I still could't withdraw much, so I set up a buy order of 1000 BTC before going to sleep, but it was forced liquidated! And my balance was at $-950, and it says my balance was dangerous low and asks me to deposit, a lose of nearly $2000 more!
Today, after waking up, I can't access my account of $-950, access denied!
I lost around $3500 in two days!
BAD!
It sounds like the sale of 20K BTC at once in a lightning sale caused your stop order to fail to function right
because the system could not sell it in time. It sold when it could.. which was after the 20K sale nailed things
down to 4.44. Pretty predictable actually and bound to happen. We discussed it briefly in the spec forum.
The other part I am not sure about. As for no access that is also worrisome.
