Investment missing?

I invested £370 into a certain share. It went crazy and my return was £886, total value £1256. I decided to sell the £886 worth leaving me with my initial investment. The price dropped a good bit leaving me with £805 total value (£886 still pending to sell) The order never got executed until the following day when the price went up another 80% but my account never reflected this then all of a sudden the sell order executed and I was only awarded my £426 return amount from the previous day? Where is my initial investment of £370 gone?

@Drewmac92 Hi. Your order was actually executed before the end of the session when there were new quotes but that was not reflected in your account until the following day. I’ll provide more details in a direct message.
