Missing 200 euro from my account after Server Crash yesterday

No worries, just adding to the above this isn’t crash related too. At any point if you place a market order say pre-market and it gaps up significantly on open and you don’t have the funds it will place a second sell order to sell just enough to cover the funds you did have. Unfortunately if this happens you’ll always lose out on the spread. Depending on the spread the wider it is the more would be lost. So in this case $2 on those 130 sold. The only way to protect against this is either foll…

I think it may be the same problem but this wasn’t a premarket order. I set the market order at a value of £5, in the past when I’ve done this and the price has changed it has either cancelled my order or just changed the amount of shares when it was filled. The sell order they put on hasn’t executed yet either. Looking at the Facebook groups it’s happened to quite a few people today and noone has a solid explanation of why. This is a few pence so I’m not that fussed but it wouldn’t be good if it happened with a substantial amount of money.

When you place a value order, it calculates the approximate number of shares and sends the order to the intermediary/exchange. The order gets filled as a number of shares rather than a value. If the price is changing rapidly the order gets filled with the number of shares before realising the difference in value, so you end paying more than you wanted.
