I completely agree with the user Itsmylife and want to give some more proof of thagoe time delay problem. Let"s see how it was before they did this upgrade:

Time difference here is just 1 second which is absolutely normal.

Here the time difference is 3 seconds which is also normal.
And here you can see my lost trade with the time interval of 3 seconds:

So as far as you can see evrything was absolutely normal about a week ago, and after their upgrade everything suddenly changed. And blockchain.info wallet has nothing to be blamed about this, because all transactions are processed as they were a week ago. The only big problem is time when secondstrade.com acceptes your trade. Intervals more than 3 seconds between receiving bitcoins and accepting one"s bet is inadmissible. lSo I really hope, that secondstrade.com admin will fix this problem as soon as possible. Otherwise, such "trading" has no sense, because almost every trade you make is gonna be lost by you. Learn on my example, yesterday I lost about 0.08 BTC and half of that size was lost due the time difference in receiving my BTC and accepting the trade by secondstrade.com.
AND THE REFUND IS STILL NOT RECEIVED!!! MAKE YOUR OWN CONCLUSIONS!
NEED A REFUND FOR YESTERDAY"S TRADES!!!
